Ayurveda the divine science of life






Pharmacology and pharmacy  
A
sava and Aris.t.
a: galenicals and
fermented liquids
A
sava and aris.t.
a are two types of fermented medicinal
preparation, the difference being the use of cold
and boiled water, respectively. A typical asava or
aris.t.
a may consist of one part (by weight) of the dried
herb mixed with 5 parts (by weight) of honey, 10 parts
(by weight) of jaggery and 25 parts (by volume) of
water. In the case of asava the above ingredients are
mixed together without heat, poured into an earthenware
vessel, sealed well, wrapped in cloth, and buried
in the ground for a period of about 1 month. Aris.t.
a
are prepared in a similar manner, except that the
dravya is boiled in the water first, and when cool,
honey and jaggery are added later. Both asava or
aris.t.
a are typically dosed between one and two
karsas (12–24 mL), twice daily. Stored in a dark
coloured vessel, in a cool location, the shelf life of an
asava or aris.t.
a can be decades, in which it will
increase in potency over time.
Vartti, netrabindu and aana:
collyriums and eye drops
Vartti are generally prepared by grinding the powders
of the various dravyas in the formula with fluids such
as water, milk, cow urine, and herbal decoctions
to make a paste, which is later rolled into thin
sticks about 2 cm in length, and then shade dried. For
administration these are applied to the lower eyelid.
Netrabindu is a filtered aqueous preparation of various
dravyas that is instilled directly into the eye.
Aana is a powder or paste of various dravyas
applied to the lower eyelid. Prepared as needed.
Ks.aras: alkalis
Ks.aras are alkaline remedies that are taken both
internally and externally. The dravyas are burnt,
reduced to an ash and allowed to cool. The ash is then
mixed with six times the volume of water and then
strained through a cloth, repeating the process until a
clear liquid is obtained. The liquid is then heated until
it has evaporated, leaving behind a solid white substance.
This is then packed into air-tight bottles and
administered with some kind of liquid, in doses ranging
from one to two guas (125–250 mg), or from
one to two mas.as (1–2 g), twice daily. Stored in a
dark-coloured vessel, in a cool location, the shelf life of
a ks.ara is indefinite.
Bhasmas: purified calcinations
Bhasmas are a kind of alchemical preparation, representing
the purified, fully calcified ash of various
substances including minerals, plants and animal
products. Depending on the dravyas used, the first
stage in preparing bhasmas is sodhana (‘purification’).
For example, a certain mineral is repeatedly
heated and then immersed into various substances
including taila, buttermilk, cow urine, decoctions
and fresh plant juices. When this process is deemed
complete the dravya is powdered and formed into
small cakes that are dried in the sun. In some cases
the result of sodhana is sufficient to be used as a remedy,
whereas other substances must continue on to
the second stage of preparation of marana, or
‘killing’, which more properly describes a bhasma.
According to traditional practices a pit of a specified
diameter and depth is dug and half filled with dried
cow dung, which is a combustible fuel. The purified,
powdered dravyas are placed into a well-sealed crucible
and put on top of the cow dung, and then covered
with more cow dung until the pit is full. The pit is
then set on fire and allowed to burn completely. After
the crucible is allowed to cool, the seal is broken and
the calcified dravyas are taken out, triturated with
various substances, and then formed into cakes that
are once again allowed to dry in the sun. These cakes
are then subjected to this process again and again,
sometimes 10, 100 or even 1000 times. The net result
is a highly purified and complex preparation that is
different from the ingredients that went into it, which
results in a significantly different biological activity.
Thus even potentially toxic minerals such as arsenic
or mercury are used.14 The preparation of bhasma is
a highly technical process that can take several
months or even years to complete, and requires special
training. Bhasmas are considered to be the most
potent of A¯ yurvedic remedies, used in small doses,
typically between a half and four gua (62.5–500
mg), mixed with various substances including honey,
ghr. ta and svarasas. Stored in a dark-coloured vessel,
in a cool location, the shelf life of a bhasma is
indefinite.

6.12 Anupana: VEHICLE
A special category of A¯ yurvedic pharmacy called
anupana relates to the usage of certain dravyas to
assist in the metabolism of the medication, or to
enhance its medicinal activity. Anupana literally
refers to drinking ‘water’ (pana) ‘after’ (anu) the
medicament has been consumed, but in a broader context
has come to mean any substance taken with or
after the medicament. Commonly used anupana
include water, milk, honey, ghr. ta, sesame oil, jaggery,
treacle, rice, saindhava, meat broth and fresh plant
juices. If a fat is used as an anupana it is usually followed
with a little warm water. Even the same dravya
has different effects when it is combined with a different
anupana. For example, the daily usage of
Harıtakı fruit (Terminalia chebula) as a malasodhana
(‘alterative’) and rasayana (‘rejuvenative’) remedy
and the choice of anupana is affected by the season in
which it is consumed. Thus Harıtakı is traditionally
taken every morning with salt during the monsoon
(vars.a), with jaggery in autumn (sarat), with Sun.t.
rhizome (Zingiber officinalis) in the first half of winter
(Hemañta) and Pippalı fruit (Piper longum) in the second
half (Sirıs.a), with honey in the spring (vasanta),
and with treacle during the summer (gris.
ma). In this
way, the various anupana modify the biological activities
of Harıtakı and make its usage more appropriate
to the given season.
6.13 Bhais. ajya kala: DOSING
STRATEGY
Compared to other medical systems A¯yurvedic medicine
maintains a relatively sophisticated dosing strategy,
dependent upon a number of factors, including
the disease being treated and the specific dos.as underlying
the pathology. The following is a list of the methods
used:
1. Abhakta: prescribed dose is taken on an empty
stomach; abhakta is the most potent of dosing
strategies, generally reserved for kaphaja conditions
or otherwise strong patients.
2. Pragbhakta: prescribed dose is taken before meals
to correct apana vayu and to reduce medas (fat).
3. Madhyabakta: prescribed dose is taken with
meals, indicated in digestive disorders to correct
samana vayu and paittika conditions.
4. Adhobakta: prescribed dose is taken after meals,
to exert a br.m.
han. a effect, in diseases of the upper
body, and in disorders of vyana and udana vayu.
5. Samabhakta: prescribed dose is taken mixed with
food, indicated in paediatric and geriatric complaints,
in patients suffering from poor appetite or
weakness, in cases where there is an aversion to
taking the medication, or where the disease has
spread throughout the body.
6. Antarabhakta: prescribed dose is taken after the
midday meal, indicated in disorders of vyana
vayu and in patients with otherwise good digestion.
7. Samudga: prescribed dose is taken before and
after a small meal, indicated in disorders of vata,
such as tremor, spasm and convulsions.
8. Muhuh. muhuh. : prescribed medication is taken frequently
throughout the day, irrespective of meal
time, in dyspnoea, vomiting, thirst and poisoning.
9. Sagrasa: prescribed dose is taken with the first
morsel of a meal, used to enhance digestion
with pana dravyas and when prescribing
vajııkaran. a dravyas.
10. Grasantara: prescribed medication is taken in
divided doses between each morsel of food, during
the evening meal, indicated in disorders of pran. a
vayu and in diseases of the heart.
11. Nis.a: prescribed dose is taken just before bedtime,
in the treatment of EENT diseases, to exert a
br.m.
han. a effect, and to promote a restful sleep
(Sharma 1976).
ENDNOTES
12 The other limbs of A
-
yurveda include anatomy (sarira), physiology
(prakr. ti vijna) and pathology (vikr.ti vijna).
13 Some texts classify lavan.
a as being laghu but this does not conform
to my experience. Excessive salt (NaCl) intake causes oedema
and promotes hypertension, both of which are kapha disorders
and occur as the result of the guru properties of lavan.
a. When
applied topically, however, lavan.
a has us.n.
a and laghu properties
and promotes the removal of kapha.
14 A recent study published by Saper et al (JAMA 292(23):
2868–2873) found that some A¯ yurvedic products contain
potentially toxic minerals such as lead, mercury and arsenic.
Unfortunately this study does not discriminate between those
products that intentionally contain these metals in significant
Pharmacology and pharmacy 77
amounts, and those that appear to be adulterated and contain
relatively small amounts. The vast majority of manufacturers in
India follow good manufacturing practices (GMPs) and can
ensure the safety and purity of their products – a very few companies,
however, and especially those that produce very inexpensive
products (i.e. ‘knock-offs’) that can be found in Indian
grocery stores, may not follow the proper GMPs, and should be
avoided. The fact that some A¯ yurvedic products intentionally
contain heavy metals is a separate issue. Such products undergo
extensive processing according to traditional methods, and the
few published studies indicate that they are safe (see: Pattanaik
et al 2003 Toxicology and free radicals scavenging property of
Tamra Bhasma. Indian Journal of Clinical Biochemistry 18(2):
181–189; Chandra & Mandal 2000 Toxicological and pharmacological
study of Navbal Rasayan – a metal based formulation.
Indian Journal of Pharmacology 32:369-371). Nonetheless,
it is understandable that practitioners in the West would be
concerned about the ingestion of heavy metals, given a similar
concern over these same metals in the food supply, vaccines
and dental amalgams. I take the opinion that A¯ yurvedic protocols
should rely on the safe, effective and natural therapies discussed
in the most ancient of A¯ yurvedic practices. While
potentially toxic purified mineral preparations may be effective,
Western practitioners will require significantly more scientific
evidence of their safety before they could ever be used in
practice.

FOOD AND DRINK
Many of the recommendations of dina-carya - and
r.
tucarya - would be incomplete without the inclusion
of a system of knowledge that guides the myriad
choices available to us in our diet. A
-
yurveda divides the
classification of diet in two basic categories,
dravadravya vijñanı-ya (‘knowledge of liquids’) and
annasvaru-pa vijñanı-ya (‘knowledge of food’).
Despite the fact that more recent texts on A
-
yurveda
suggest that there are certain dietary regimens that are
best suited to the individual dos.as, this is not a concept
found in any traditional text on A
-
yurveda. Traditional
A -
yurvedic physicians recognise that there are certain
foods that influence the individual dos.as, and that
a true understanding of diet comes from appreciating
each individual dietary article, rather than memorising
a list of dietary ‘dos and don’ts’. Most of the foods mentioned
in these ancient texts, however, are outside of
India, and thus we are left to consider non-Indian foods
from an A
-
yurvedic perspective. Beyond any regimen, all
diets for all people should be healthy, diverse and wholesome,
and attempt to reflect the season and the local
ecology.
7.1 WATER
Of the liquids, water is considered to be the most
important in A
-
yurveda. The biological activity of
water is said to be different if it is hot, tepid or cold, and
its qualities are dependent upon the location from
which it is collected. It is fairly clear from the ancient
texts that the utmost importance was attached to making
sure the source of water was pure and uncontaminated.
In ancient India freshly collected rainwater was
highly valued for health. It is said to be rejuvenating

(rasa¯yana), strength promoting (balya), life giving
(jı¯vanı¯ya), promotes contentment (sukha), enhances
the intellect (medhya), and alleviates all three dos.as.
In this industrial age, however, rain often contains the
residue of airborne pollutants. These industrial pollutants
are now dispersed widely across the entire surface
of the earth, and although one may live in a pristine
environment this does not mean that the rainwater is
not contaminated.
According to A
-
yurveda the water from fast-flowing
glacial rivers is considered to be the best substitute for
rainwater; it is rasa-yana (‘rejuvenative’), and alleviates
all three dos.as. The water from slower flowing
rivers and streams, which is murky and brown, contains
algae and other plant material said to promote
congestion, parasitic infection, circulatory disturbances,
and aggravate all three dos.as. The water from
underground springs alleviates kapha, promotes
digestive function, and is hr.daya (‘cardiotonic’). The
water collected from artesian wells stimulates digestion
function, alleviates kapha, and aggravates
pitta. Lake water can relieve the symptoms of excessive
pitta, whereas water taken from ponds and small
pools aggravates va-ta. Water that has been collected
and allowed to sit in a crystal vessel and exposed to
the rays of the sun all day, and then exposed to the
rays of the moon all night, is said to be rasa-yana
(‘rejuvenative’), balya (‘strength-promoting’), medhya
(‘intellect-promoting’), and alleviates all three
dos.as.
Water in excessive amounts is considered detrimental
for persons suffering from agnima-ndya (weak
digestive function), and is thus consumed in lesser
quantities in such situations. Clearly the modern practice
of consuming eight glasses of water a day is not
appropriate for every person. Small amounts of water
on a frequent basis are better for hydration, whereas
large amounts of water consumed all at once is
mu¯travirecana (‘diuretic’) and virecana (‘purgative’).
With regard to the seasons, water should be consumed
in greater quantities in the summer, and less so in the
other seasons, but as it is essential to life it is never prohibited
completely. The best guide to water consumption
is to rely on one’s desire for it (e.g. thirst), and to
watch for symptoms associated with dehydration such
as dryness of the oral cavity, constipation, headache or
low blood pressure. The consumption of water before
eating inhibits digestive function, promotes weight loss
and aggravates va-ta. Consuming water after meals
promotes congestion, weight gain and aggravates
kapha. Drinking small amounts of water after every
few mouthfuls with meals enhances digestive function
and promotes the normalcy of the dos.as.
Cold water relieves the effects of aggravated pitta
and poison, inhibits digestion, and is useful for intoxication,
exhaustion, fainting, fatigue, vertigo, thirst,
heat and sunstroke. Cold water is contraindicated in
constipation, flatulence, throat diseases, nascent
fevers, rhinitis, upper respiratory tract infections,
coughs, hiccoughs, chest pain, urinary tract disorders,
cataracts, anorexia, anaemia, poor circulation and
tumours. Cold water is not taken after snehapa-na,
a therapy in which a large amount of oil is ingested
orally (see 11.3 Pu-rva karmas: snehana).
Warm water stimulates digestive function, soothes
throat irritations, cleanses the urinary tract, relieves
hiccoughs and dispels intestinal fermentation. It is particularly
suitable for both va-ttika and kaphaja conditions,
and finds its best use in the nascent symptoms of
an upper respiratory tract infection. Water that has
been boiled to three quarters of its original volume is
stated to alleviate va-ta; that which has been boiled to
one half its original volume alleviates pitta; and water
that has been boiled to one quarter of its original volume
is constipative and alleviates kapha. This ability
to modify the effect of boiled water is a useful factor to
take into account when preparing decoctions (kva - tha)
for individuals. Hot water is contraindicated in physical
and mental exhaustion, convulsions, bronchial
asthma, hunger and haemorrhage. Boiled water that
has been cooled is best for both kaphaja and paittika
conditions, but if left overnight will aggravate all three
dos.as.
Water is an extremely important substance, and in
many respects is the ultimate anupa-na, acting as
a solvent and carrier for the medicinal substances it is
mixed with. Depending upon its quality and source,
water can energise and potentise a medication, or it
can impinge or inhibit a medicinal effect. Water also
appears to have the ability to record influences upon
itself, and can be energised by succusion, meditation
and prayer. To some extent these ideas are supported
by scientific research, most notably in the work of
physicist Louis Rey of Lausanne, Switzerland, who
suggests that water has a kind of ‘memory’ of molecules
that have been diluted away, demonstrated by
a technique that measures thermoluminescence (Rey
2003).
Food and drink 81
7.2 DAIRY PRODUCTS
Milk is given much importance in A
-
yurveda, and the
milk of different animals has distinct dietary and therapeutic
applications. As in the West, cow’s milk is by
far the most commonly consumed milk in India,
although for many people (especially in non-urban
areas) milk is obtained fresh, unpasteurised and
unprocessed. In constrast, the industrial product called
milk in the Western world that is heavily promoted by
government agencies, marketing boards and the dairy
industry, is in many respects an entirely different substance
to the health-giving food that cow’s milk was
considered to be in the ancient A
-
yurvedic texts.
Herbicide and pesticide residues that act as carcinogens
and endocrine disrupters, pathogenic bacteria,
the presence of growth hormones, antibiotic residues
and heavy metal contaminants like cadmium have all
contributed to make industrial cow’s milk an unfit
product for regular consumption. At the least I recommend
that cow’s milk be as fresh as possible, preferably
from a local supplier or one’s own animals, unpasteurised
and free from herbicides, pesticides, hormones
and antibiotics.
Besides those factors mentioned above, there are
two more factors to consider before consuming any
kind of milk:
1. Sa-tmya: the consideration of whether milk is an
appropriate food for a particular person, based on
cultural and racial differences. Most East Asian
people, for example, do not produce the enzyme
lactase needed to break down the milk sugars, and
can experience severe intestinal cramping and
bloating after dairy consumption. Other people
regardless of race also exhibit allergies and sensitivities
to cow’s milk, in all likelihood because of
its premature introduction into the diet as young
children or infants.
2. Agni and a - ma: the digestive capacity of one who
wishes to consume milk must be taken into
account. When digestion is weak, there is usually
a -
ma. If milk is consumed in such a scenario, agni
will continue to be impaired and the undigested
milk will feed a - ma.
Go dugdha (‘cow’s milk’) is considered to be guru
(‘heavy’) and snigdha (‘greasy’) in nature, s´ita (‘cold’)
in action, rasa-yana (‘rejuvenative’), br.mhan. a
(‘nourishing’), stanyajanana (‘galactagogue’), and
bhedhana (mildly ‘laxative’), alleviating va-ta and
pitta. Go dugdha increases kapha and promotes srotorodha
(srota ‘congestion’) in a - ma conditions. The
milk of a black cow is considered to be the most wholesome,
whereas the milk of a white cow is stated to
aggravate kapha. Although all milk is best consumed
fresh, if cow’s milk must be pasteurised it is best
decocted with kat.u dravyas such as S´ u-n.
t.hı- rhizome
(Zingiber officinalis), Ela- seed (Elettaria cardamomum)
and Tvak bark (Cinnamomum zeylanicum) and drunk
warm.
Takra (‘buttermilk’) is the somewhat acidic liquid
separated from butter during churning, considered to
be s´ita in nature, dı-panapa-cana (enhances agni
and ‘cooks’ a - ma), and stambhana (‘constipating’). It
is useful in the treatment of throat irritation and
inflammation, but like cow’s milk is avoided in srotorodha.
Takra is especially useful in the treatment of
and recovery from dysentery, often boiled with
herbs such as Haridra - rhizome (Curcuma longa),
u¯n. t.hı- rhizome (Zingiber officinalis), and fresh curry
leaves (Bergera koenigii).
Aja- dugdha (‘goat’s milk’) is similar to cow’s milk in
many respects, but is laghu (‘light’) in nature, dı-pana
(enhances agni), stambhana (‘constipating’), and is
particularly useful for cachexia, haemorrhoids, diarrhoea,
menorrhagia and fever. In many areas of India
aja- dugdha is the first choice when weaning children
off breast milk. Like cow’s milk, goat’s milk should be
consumed warm, and can be similarly decocted with
kat.u dravyas. Due to their instinsic nature, goats cannot
be intensively farmed like cows, require large pastures
to browse in, and thus typically eat a broader range
of foods than cows. Thus goat’s milk is in every way
superior to industrial cow’s milk, and often contains a
broader range of nutrients.
Avi dugdha (‘sheep’s milk’) can also be thought of as
an alternative to cow’s milk. It is guru (‘heavy’) and
snigdha (‘greasy’) in nature, and is considered to be
almost identical to cow’s milk, useful in paittika and
va¯ ttika conditions, dry hacking coughs, and alopecia.
Mahisi dugdha (‘water buffalo milk’) is excessively
guru (‘heavy’), snigdha (‘greasy’) and s´ita (‘cold’) in
nature. It is most often used by the poorer classes in India
instead of cow’s milk, and imparts a similar flavour to
goat’s milk. Given its heavy and greasy properties
mahisi dugdha is used therapeutically for a condition
called bhasmika, in which dietary articles pass through
PART 1: Theory and practice of A
-
82 yurveda
the patient very quickly and the hunger is insatiable.
Water buffalo milk is also said to be stambhana (‘constipating’),
balya (‘enhances strength’), and nidra - -
janana (‘promotes sleep’).
Navanı-ta is fresh butter churned from cow’s milk,
and is vajı-karan. a (‘aphrodisiac’) and specific to
va-ttika and paittika complaints. Ghr. ta or ghee is
made by heating fresh unsalted butter over a low heat
and rendering the pure butter oil from the milk solids,
the latter of which are discarded. The rasa of ghr. ta is
madhura (‘sweet’), its vı-rya is s´ita (‘cold’), and its
primary gun.as are guru (‘heavy’) and snigdha
(‘greasy’). When applied topically ghr. ta is antiinflammatory
and finds special utility in skin conditions
such as eczema, rashes, ulcers, and herpetic
lesions, especially when medicated with raktaprasadana
(‘blood-cleansing’) dravyas, e.g. Maha-tikta
ghr. ta. Medicated ghr. ta preparations are also used in
oleation therapies (abhyan . ga) for their ability to treat
psychological disturbances (e.g. insanity, bipolar disorders)
and other nervous system disorders (e.g. epilepsy,
paralysis). Ghr. ta is an important medicament used in
the treatment of many ophthalmological disorders,
and is often decocted with the formula Triphala for
this purpose. Internally, ghr. ta is used with other herbs
as an anupa-na and is yogava - hı-, meaning that it contains
the ability to augment the effects of any medicinal
agent combined with it. Ghr. ta is especially suited
to paediatrics and geriatrics, and is a rasa-yana in
paittika conditions. Ghr. ta is considered a highly auspicious
food within Hindu culture, and is used in many
forms of pu-ja (‘worship’) ceremonies as an agent of
purification. Ghr. ta is often combined with honey for
its nutritive effects, but never in equal quantities.
Although it is a rasa-yana and can help to improve
digestive function, ghr. ta can block the channels of
the body (srotorodha) and promote the accumulation
of a - ma if agni is weak. Ghr. ta that has been aged in
excess of 10 years is thought to be much stronger in its
overall action than fresh ghr. ta, and has a kat.u (‘pungent’)
vipa-ka, is prama-thi (decongests the srota--
m.
si), medhya (‘intellect promoting’) and alleviates all
three dos.as. It is a tradition among some Indians to
bury well-sealed vessels that contain ghr. ta that are to
be dug up several years later and used by succeeding
generations.
When cow’s milk is allowed to ferment the resultant
preparation is dadhi or curd (yoghurt). Although high
in beneficial commensal bacteria (e.g. Lactobacillus,
Bifidus), it is generally not recommended for daily consumption
in A
-
yurveda. Generally speaking, dadhi promotes
digestion, is constipative and strengthening. It is
specific for diarrhoea and dysentery, anorexia, dysuria
and in chronic fever where a - ma has been removed
(nira¯ma jvara). Dadhi is thought to promote congestion
(kleda) and burning sensations (daha), which can
lead to fever, diseases of the blood, cold sores and other
skin diseases. There are different varieties of dadhi,
however, each classified on the basis of the fermentation
period. Dadhi that has been fermented for a short period
of time is stated to have a madhura (‘sweet’) rasa, and
can be helpful to relieve va-ta and pitta, whereas dadhi
that has been fermented for longer has a kat.u (‘pungent’)
rasa, better used in kaphaja conditions.
A -
yurveda recommends that dadhi should be consumed
by itself, or with honey or jaggery, and never in the
evening. The watery portion of dadhi, called mastu,
has all of the benefits of dadhi but none of its disadvantages
and is an excellent food, containing the highest
amounts of beneficial bacteria.
Panir is a cultured dairy product that very much
resembles what in the West is called cottage cheese or
kefir. Panir is guru (‘heavy’), snigdha (‘greasy’)
and mildly s´ita (‘cold’) in nature and is a good food in
va-ttika and paittika conditions only as long as agni
is strong enough to digest it. Panir tends to promote
kleda (‘congestion’), and hence is an especially poor
choice in kaphaja conditions. Most other kinds of
cheese that are available in the West such as cheddar,
montery jack and mozzarella are excessively guru
(‘heavy’) and snigdha (‘greasy’) in quality, and are
intolerable in anything except small amounts or in
those people with a tiks.n.
a agni. Aged and hard
cheeses such as parmensan, romano and feta have
a kat.u (‘pungent’) rasa and can be used in va-taja and
kaphaja conditions in small amounts.
Even though many people within the last few generations
in the West missed out on it, it is now clearly
established that human milk should be the first food of
any newborn. Therapeutically, the milk of lactating
women alleviates va-ta and pitta without aggravating
kapha, nourishes the dha-tus, and stimulates digestive
function. Breast milk finds special therapeutic utility in
diseases of the eye, such as conjunctivitis, and can be
mixed with other herbal preparations for more serious
ophthalmological conditions. Breast milk is also used
in nasya for diseases of the head and in neurological
disorders.

7.3 FRUIT
Most fruits generally aggravate kapha and relieve
pitta because of their s´ita (‘cold’) and guru (‘heavy’)
qualities, and depending upon the kind of fruit, may
aggravate or pacify va-ta. Of all the fruits A
-
yurveda
considers dra - ks.a - (‘grapes’) to be among the best, but
these of course must be organically produced or otherwise
naturally grown, and I believe, also refers to eating
the seeds along with them, which contain potent
anti-oxidant compounds. The following list describes
the actions of fruits upon the dos.as:
Aggravates va-ta
Dried fruit, cranberries, sour and acid-tasting
fruits, unripe fruit.
Pacifies va-ta
Most local and seasonal fruits, consumed individually
and in small amounts, e.g. raspberry, strawberry,
pear, blueberry, peach, grape, and apple.
Cooked fruits such as baked apples, baked pears,
and stewed fruit (e.g. prunes, raisins, etc.), prepared
with ghr. ta and dravyas such as Tvak bark
(Cinnamomum zeylanicum) and Ela- seed (Elettaria
cardamomum).
Any tropical fruit, e.g. mango, pomegranate,
papaya, guava, litchi (lychee), melon, banana, etc.
Aggravates pitta
Sour and acid-tasting fruits, including lemons, sour
oranges; papaya or strawberry consumed to excess.
Pacifies pitta
Most local and seasonal fruits can be eaten freely,
such as raspberry, plum, pear, cranberry, grape,
and apple; sweet citrus fruits can also be consumed
in moderation.
Most tropical fruits, e.g. mango, pomegranate,
papaya, guava, litchi, melon, banana, etc.
Aggravates kapha
Most fruits are generally avoided because of their
excessive water content (snigdha) and cold (s´ita)
nature.
Pacifies kapha
Small amounts of dried fruit, cranberry, grapefruit,
lemon, lime, and sour-tasting fruits.
7.4 VEGETABLES
Among all the different foods, vegetables stand out for
their health-giving properties and their generally beneficial
effects upon all three dos.as. In this respect vegetables
are closely allied with medicinal plants, some
such as S´u-n.
t.hı- (Zingiber officinalis) and Las´una
(Allium sativum) straddling the definition of food and
medicine. Although all vegetables are generally beneficial
each dos.a may require that these vegetables be
prepared by a specific method.
The consumption of raw vegetables is generally not
advised in A
-
yurvedic medicine due to their excessively
s´ita (‘cold’) vı-rya, and are specifically contraindicated
in va-ttika and kaphaja conditions. To some extent
the issue also relates to potentially pathogenic microorganisms
that can be found on raw vegetables, especially
in developing countries that often lack sufficient
sanitation. In most cases raw vegetables should be
avoided, and at the least should be lightly steamed or
juiced, preferably with dravyas that have an us.n.
a
(‘hot’) vı-rya such as fresh ginger root, garlic and shallots.
In contrast, paittika conditions may benefit from
limited amounts of raw vegetables such as celery and
carrot sticks to cool the body and reduce excess heat.
Fried vegetables are only really indicated in va-ttika
conditions, and aggravate both pitta and kapha, and
can promote a - ma. Most deep-fried foods are similarly
congesting and even toxic considering their transfatty
acid content – at the least, deep-frying should use heatresistant
oils such as ghr. ta and coconut oil. The following
lists the interaction between vegetables and the
dos.as:
Aggravates va¯ta
Raw vegetables generally, mushrooms,15 potatoes.
Pacifies va¯ta
All cooked vegetables generally, but especially root
vegetables and winter squashes, steamed, boiled,
baked or stir-fried.
PART 1: Theory and practice of A
-
84 yurveda
Well-cooked onions and garlic.
Cruciferous vegetables (broccoli, cabbage, etc.) are
s´ita (‘cold’) and laghu (‘light’) in nature, and
should be cooked with ginger or other herbs such as
cumin, rosemary, and garlic, and consumed with
fats such as butter, olive oil or ghr.ta.
Seaweed, in soups and broths.
Fermented vegetables, e.g. sauerkraut, pickles,
umeboshi plum.
Aggravates pitta
Onions, chilies, tomatoes, eggplant (aubergine),
garlic, turnip, radish, avocado, watercress, seaweed,
pickles.
Pacifies pitta
Most vegetables, preferable steamed, juiced or raw,
especially cooling vegetables such as leafy greens,
cucumber, lettuce, dandelion, cilantro, sprouts and
celery.
Aggravates kapha
Raw vegetables, mushrooms.
Fried vegetables.
Pacifies kapha
All vegetables, steamed or baked.
Bitter or pungent tasting leafy greens.
Raw vegetables only with us.n.
a (‘hot’) dravyas
such as cayenne and black pepper.
Sprouted beans and seeds in moderation.
Small amounts of fermented vegetables and
unsweetened pickles.
7.5 GRAINS AND CEREALS
Most grains and cereals have a madhura (‘sweet’) rasa,
a guru (‘heavy’) and us.n.
a (‘hot’) vı-rya, and are mostly
br.mhan.a (‘nourishing’) in action. Grains and cereals
are thus generally considered to be most appropriate in
va-ttika conditions, although certain grains, such as
rice, barley, quinoa or amaranth appear to be suitable to
all three dos.as.16 Refined cereals such as white flour that
have been stripped of their original nutrient content
aggravate all three dos.as, promote a - ma and should be
avoided. Whole grain flour, although largely considered
to be better than white flour, can still impair gastric
motility and aggravate kapha, weaken agni, and facilitate
the production of a - ma due its guru and picchila
nature. Whole grain flours are also particularly susceptible
to rancidity, due to the polyunsaturated fat content,
and should be freshly ground and used as soon as possible.
Generally speaking, it is best to consume boiled or
naturally fermented grains, such as oatmeal and
steamed rice, or homemade idli (fermented rice/urad
bean cakes) and sourdough bread. It has become
increasingly clear that a long-term diet rich in grains and
cereals poses several potential health problems. Foods
with a high glycaemic index can promote alterations in
blood sugar, leading to hypoglycaemia, as well as induce
a state of hyperinsulin secretion and insulin resistance,
leading to diabetes and cardiovascular disease. Grains
and cereals also contain a chemical called phytic acid
that binds to certain minerals such as calcium and iron,
and minimises their absorption in the digestive tract to
promote nutrient deficiencies. Further, a diet rich in
grains may also be abundant in compounds called
lectins, which irritate and inflame the gut wall. Thus, in
many cases, a grain-based diet is contraindicated in
inflammatory bowel disorders, and in autoimmune conditions
like a - mava-ta (rheumatoid arthritis) that are
thought to have an enteropathogenic origin. Despite the
fact that the modern Indian diet obviously relies upon
grains and legumes to feed an enormous population,
there is no indication in the extant A¯yurvedic literature
that a primarily grain-based or vegetarian diet should
take preference over a more balanced diet: indeed, the A
-
yurvedic texts recommended a wide assortment of
foods, including meat, to maintain health.
The following list details the effects of grains and
cereals upon the dos.as:
Aggravates va¯ta
Insufficiently cooked grains; grain foods with light
(laghu) and dry (ru-ks.a) properties such as granola,
muesli, corn, millet, yeasted bread, popcorn,
rice cakes, puffed grains, tortilla chips.
Pacifies va¯ta
Boiled and fermented grains, including oats, rice,
rice noodles, quinoa, amaranth, buckwheat, khusFood
and drink 85
khus (couscous), whole wheat pasta, whole wheat
chapatti, corn flour tortilla, sourdough bread
(lightly toasted).
Aggravates pitta
None, except light or toasted grains consumed to
excess (e.g. granola, muesli, corn, millet, bread,
popcorn, rice cakes).
Pacifies pitta
Boiled and toasted grains, including oats, rice, rice
noodles, quinoa, amaranth, buckwheat, khuskhus,
whole wheat pasta, whole wheat chapatti, corn flour
tortilla, sourdough bread (lightly toasted).
Aggravates kapha
Most grains, especially white rice, yeasted bread,
pasta, wheat, rye and oats.
Pacifies kapha
Boiled and fermented rice, quinoa, amaranth, millet,
barley, corn; grain foods with light (laghu) and dry
(ru-ks.a) properties such as granola, muesli, corn,
millet, popcorn, rice cakes, puffed grains, etc.
7.6 LEGUMES
Although legumes are an important non-animal source
of protein, they typically display a ru-ks.a (‘dry’), laghu
(‘light’) and s´ita (‘cold’) vı-rya, and hence most are contraindicated
in va-ttika conditions. Similar to grains and
cereals, legumes have been shown to contain potentially
toxic or health-damaging constituents, such as lectins,
phytates and protease inhibitors. Thus legumes may
promote nutrient deficiencies, which is in keeping with
the A
-
yurvedic perspective, as well as inflame the intestinal
wall, and thus are contraindicated in inflammatory
bowel disease and autoimmune disorders. Like grains
and cereals, most legumes are rich in carbohydrates,
and should be avoided in hypoglycaemia and diabetes, or
at least be consumed with fats and oils to lower the glycaemic
index. Some legumes such as soy are now very
common in our modern diet, often as a hidden ingredient
in prepackaged foods and meat, and many people are
allergic or have sensitivities to soy. As legumes will typically
provoke va-ta in most people, they should be soaked
overnight, cooked with ginger and other us.n.
a (‘hot’)
dravyas, and eaten with fat such as ghr. ta. In countries
like Japan, beans such as soy are rarely consumed without
first being fermented, as in natto, miso and tempeh,
which helps to deactivate some of the health-damaging
constituents. Another frequent error that is made when
preparing bean dishes such as dahl is using too great a
volume of beans. According to traditional Indian cookery,
dahl is a thin, watery broth made with beans and
spices. In a given meal, the actual volume of beans consumed
is actually fairly small. Many Westerners that
emulate an Indian diet prepare far too large an amount
needed for one meal, and mistakenly rely upon this as
their primary source of protein, eschewing the benefits
of egg or dairy in an otherwise vegetarian diet. The primary
reason why most people in India exlusively rely
upon legumes as their primary source of protein is
because of extreme poverty, although some believe
a vegetarian diet more beneficial to cultivate a sattvic
state of mind.17
The following lists the effects of legumes upon the
dos.as:
Aggravates va¯ta
All legumes, including soy, lentils, split peas, kidney,
garbanzo, lima, pinto, navy, peanut.
Pacifies va¯ta
There are no beans that truly pacify va-ta, but
some legumes and legume products such as urad
dhal (black gram), adzuki, mung, soft tofu, natto,
and tempeh can be consumed in moderation if
prepared with warming herbs and spices such as
ginger, cumin, garlic, basil and oregano.
Aggravates pitta
Peanut.
Pacifies pitta
Most legumes are acceptable for pitta, but because
they have a laghu (‘light’) vı-rya they should not
be consumed to excess.
PART 1: Theory and practice of A
-
86 yurveda
Aggravates kapha
Peanut, urad dhal.
Pacifies kapha
Most legumes are useful for relieving kapha, used
in moderation.
7.7 NUTS AND SEEDS
Nuts and seeds are the most br.mhan. a (‘nourishing’)
foods of the vegetable kingdom, and are an excellent
source of dietary fat. Nuts and seeds are the fruit of the
plant, the final dha-tu produced, and are closest in
quality to s´ukra/an.d.
a-n.
u (semen/ovum) in humans.
Thus nuts and seeds directly nourish the reproductive
organs, if taken in appropriate amounts. The vı-rya
of most nuts and seeds is guru (‘heavy’), snigdha
(‘greasy’) and us.n.
a (‘hot’). Care should be taken to eat
nuts and seeds as fresh as possible, as many will
become rancid shortly after being hulled. Many nuts
such as pistachio also contain high levels of fungal
mycotoxins that result from improper storage and act
as liver carcinogens. If taken in excessive amounts,
nuts and seeds facilitate the production of a-ma and
will aggravate kapha. The following lists the effects of
nuts and seeds on the dos.as:
Aggravates va¯ta
None, except in large amounts (i.e. more than
a small handful), and improperly chewed.
Pacifies va¯ta
Flax, hemp, sesame, pumpkin, walnut, cashew, sunflower,
coconut, pecan, filbert, brazil, almond, etc.
Aggravates pitta
Most nuts and seeds are generally avoided in
paittika conditions because of their snigdha
(‘greasy’) and us.n.
a (‘hot’) vı-rya.
Pacifies pitta
Pumpkin seeds, coconut, almond, melon seeds.
Aggravates kapha
Most nuts and seeds are generally avoided in
kaphaja conditions because of their snigdha
(‘greasy’) and guru (‘heavy’) vı-rya.
Pacifies kapha
Pumpkin, melon seeds.
7.8 MEAT AND ANIMAL PRODUCTS
Of all the food groups, meat and animal products are
the most br.mhan. a (‘nourishing’), and are generally
considered to have a guru (‘heavy’), snigdha
(‘greasy’) and us.n.
a (‘hot’) vı-rya. Meat and animal
products generally pacify va-ta, but some can aggravate
both pitta and kapha.
Although India is renowned for its vegetarian culture,
A
-
yurveda does not prohibit meat as a dietary article,
and nor are the vast majority of people in India
vegetarian, at least by choice. It is clear that traditional
A -
yurvedic medicine considered meat to be an excellent
food to relieve deficiency (langhana) conditions. In the
West, however, gross nutritional deficiency is rarely an
issue, although many people feel much better when they
consume good quality meat on a daily basis, especially if
they live in cold, dry climates. In northern climes it is
clear that animal products have always been an important
staple to people that reside in these areas, and if living
in such a climate, it is as well to follow these
practices. It is important to remember, however, that
meat carries with it a greater investment in the economy
of cause and effect, when a sentient being is killed
and eaten to nourish another. Above all, meat is a
medicinal food, and should be consumed when needed,
with respect and honour for the animal which has sacrificed
its life to nourish your own. If such an approach
were taken in the West, much of the objectionable and
cruel practices of the meat industry would be replaced
by those that preserve and honour the dignity of the
animal. Further, industrially produced meat is typically
deficient in key trace minerals, low in omega-3 fatty
acids, high in saturated fat, and rife with antibiotic and
hormone residues. Such meat and animal products
should be avoided in all conditions in favour of those
that are organically grown, pasture-raised and freerange.
Food and drink 87
The consumption of the different kinds of meat can
be based upon the nature of the animal in relation to
the dos.as. Thus, timid animals such as rabbit and venison
might be avoided in va-ttika conditions but are used
in kaphaja conditions because of their comparatively
laghu (‘light’) and ru-ks.a (‘dry’) vı-rya. Passive and
sedentary animals such as beef and buffalo are contraindicated
in kaphaja conditions, but are useful in
va-ttika conditions because of their sthira (‘stable’),
sa-ñdra (‘solid’) and madha (‘slow’) qualities. Red meat
is generally avoided in paittika conditions, but is useful
in va-ttika conditions because of its comparatively
us.n.
a (‘hot’) vı-rya (indicated by the red colour of the
meat). The us.n.
a property of lean red meat can be
appropriate in kaphaja if the animals are not sedentary,
such as venison, moose or elk. Goat meat and mutton
are two of the few red meats that are tolerated in
paittika conditions, are similarly helpful in vattaika
conditions, and can even be used in kaphaja conditions
in small amounts. Most fish is good for all three
dos.as but tropical fish is said to have an us.n.
a (‘hot’)
vı-rya and is traditionally avoided in paittika conditions.
Cold water fish, however, is unlikely to have this
effect, although cold water fish with a high fat content
is contraindicated in kaphaja conditions.
The following details the effects of the different
kinds of meat upon the dos.as:
Aggravates va¯ta
No meat is contraindicated for va-ta, but some
meats such as pork and beef can be difficult to
digest, and should be consumed in small
amounts and with herbs and spices that enhance
digestion.
As va-ttika conditions speak of an extreme sensitivity
to psychic stimuli, the act of killing an animal
for food carries with it a downward moving, negative
energy that can act in opposition to the nourishing
qualities of the meat. In such conditions, the
kind of meats should be chosen carefully, selecting
only meat that has been cared for lovingly during
its life and sacrificed humanely.
Pacifies va¯ta
Almost all meats pacify va-ta, especially those
cooked in soups and stews with kat.u (‘pungent’)
dravyas such as onion, shallots, garlic, ginger, etc.
Acceptable animal products include eggs, poultry
(especially duck and goose), wild fish, shellfish, wild
game, beef, pork, goat, lamb, mutton, etc.
Aggravates pitta
Pork, beef, tropical fish, shellfish.
Pacifies pitta
Poultry (particularly the white meat), cold water
fish (salmon, halibut, herring, etc.), fish roe, rabbit,
goat, lamb, mutton.
Aggravates kapha
Pork, beef, lamb, fish, shellfish.
Pacifies kapha
Poultry, wild game, goat, rabbit.
7.9 FATS AND OILS
Fats and oils are an important food, medicament and
vehicle (anupa-na, see Ch. 6) in A
-
yurvedic medicine.
Generally speaking, oils and fats are a primary treatment
to va-ta due to their generally moistening and
warming nature. They are typically used to a lesser
extent in paittika and kaphaja conditions, although
some oils are an exception to this rule.
The most commonly used oil in A
-
yurvedic medicine
is sesame oil (taila). Taila is the cold-pressed oil from
raw tila (‘sesame seed’) and is the primary medium
for the many medicated oils used in A
-
yurveda. Taila
has a madhura (‘sweet’) rasa, an us.n.
a (‘hot’) and
guru (‘heavy’) vı-rya, and is bhedana (‘aperient’),
vajı-karan. a (‘aphrodisiac’), balya (‘strength promoting’),
varnya (‘enhances complexion’), and pacifies
va-ta. Taken internally in large amounts taila is
vida-hi (‘promotes burning sensations’), and can
be used in the treatment of intestinal parasites
(kr. mighna). Used topically taila is medhya (‘intellect
promoting’), romsañjanana (‘promotes hair
growth’), dı-pana (‘enhances agni’), and balya
(‘counters fatigue’).
Besides taila, ghr. ta is the next most commonly
used oil, used in both cooking and as a medicine.
PART 1: Theory and practice of A
-
88 yurveda
A number of other oils are also used, however, and
the following is a list of common food oils used in
both A
-
yurveda and in the West, and their effects
upon the dos.as. Needless to say, perhaps, but this list
refers only to high-quality, fresh, cold-pressed ‘extravirgin’
oils, and generally not to those that have been
refined or rendered with the use of chemical solvents
or heat:
1. Olive: decreases va-ta, increases pitta and
kapha
2. Coconut: decreases va-ta and pitta, increases
kapha
3. Sunflower: decreases va-ta and pitta, increases
kapha
4. Safflower: decreases va-ta and pitta, increases
kapha
5. Walnut: decreases va-ta, increases pitta and
kapha
6. Flax: decreases va-ta and pitta, increases
kapha
7. Hemp: decreases va-ta and pitta, increases
kapha
8. Castor: decreases va-ta and kapha, increases
pitta
9. Mustard: decreases va-ta and kapha, aggravates
pitta
10. Almond: decreases va-ta and pitta, aggravates
kapha
11. Canola: decreases va-ta and pitta, aggravates
kapha
12. Peanut: aggravates all three dos.as
13. Fish: decreases va-ta and pitta, increases
kapha.
Although there is no mention of them in the
A -
yurvedic literature it is clearly wise to avoid both
hydrogenated oils and trans-fatty acids, as the consumption
of these fats has been shown to promote a
wide range of diseases, including cancer and cardiovascular
disease. This includes margarine, most oils
added to packaged foods, blackened meat from high
heat broiling, and any vegetable, fruit or seed oil sold in
a clear container without refrigeration (monounsaturated
fats such as olive oil are to some extent an exception
to this rule). In a similar fashion, the fat of meat
from animals raised in large industrial operations and
fed only grain-based fodder is exceptionally unhealthy,
much higher in saturated fat and concomitantly lower
in essential omega-3 fatty acids than that found in pasture-
raised, grass-fed animals.
7.10 SWEETENERS
There are many kinds of sweetener used in A
-
yurvedic
medicine, mostly as anupa-na. Sweets are also very
popular as a food and condiment in India, but this is
not reflective of the perspectives found in ancient texts
like the Caraka sam. hita- or As. t.a - ñga Hr.
dayam.
Intensely sweet foods such as cane sugar and honey
are considered to be a kind of medicine in A
-
yurvedic
medicine, with powerful healing properties. Used to
excess, however, or simply to feed the impulses of the
tongue, sweet foods are a kind of poison that aggravates
all three dos.as.
Madhu (‘honey’) is a highly valued sweetener in
A -
yurveda, and is considered to be ru-ks.a (‘dry’), us.n.
a
(‘hot’) and somewhat guru (‘heavy’) in nature. Madhu
is dı-panapa-cana (‘enhances agni’ and ‘cooks’ a - ma),
gra - hı- (‘checks excessive secretion’), s´on. itastha-pana
(‘antihaemorrhagic’), varnya (‘enhances complexion’),
medhya (‘promotes intellect’), vajı-karan.a (‘aphrodisiac’),
and alleviates kapha. Taken internally madhu
is used in the treatment of peptic and duodenal ulcer,
bronchitis, asthma, hiccoughs, vomiting and diarrhoea.
Externally, honey is used to heal bruises, soothe inflamed
skin, resolve ulcers, unite broken bones and enhance the
complexion. Like ghr. ta, madhu is yogava - hı-, enhancing
the activity of the medicaments taken with it.
Madhu may be used safely with ghr. ta (but only in
disproportionate quantities) for va-ttika disorders,
and as an anupa-na for rasa-yana (‘rejuvenative’) and
vajı-karan.a (‘aphrodisiac’) therapies. Madhu is a mild
irritant to pitta, which is offset if at least twice the
amount of ghr. ta is used in combination. Aged
madhu has less of the nourishing, br.mhan. a qualities
of fresh honey, but has a greater ability to alleviate
kapha.
A -
yurveda prohibits the internal use of heated honey.
This is because wild bees gather nectar indiscriminately
from any kind of plant, regardless of whether the plant is
toxic or not. Thus all honey contains a certain amount of
toxins,18 and because the nature of poison is us.n.
a, when
honey is heated the latent toxins become active. This is
also why the internal consumption of madhu is avoided
in hot weather.19
Food and drink 89
Gud.a, or jaggery (solidified cane sugar juice), is
snigdha (‘greasy’), s´ita (‘cold’) and guru (‘heavy’) in
nature, and is by far the best sweetener and anupa-na to
use in paittika conditions. It may be used in va-ttika
conditions as well, as long as the dravya accompanying
it has an us.n.
a (‘hot’) property, but should be
avoided in kaphaja disorders, and can promote kr.mi
(‘intestinal parasites’). Gud.a is said to be bhedana
(‘aperient’) and balya (‘strength promoting’), and is
used therapeutically in the treatment of dahi (‘burning
sensation’) and tr.s.
n.
a -
(‘thirst’). Aged gud.a, however, is
said to have a laghu nature, and is considered to be
hr. daya (cardiotonic) and nourishing. Refined gud.a,
which includes both white and ‘brown’ (caramelised)
sugar, aggravates all three dos.as, promotes kr.mi (‘parasites’),
and should be avoided. Molasses is guru
(‘heavy’) and snigdha (‘greasy’) in nature, and is well
suited to va-ttika conditions. Maple syrup and other
syrups derived from tree sap are similar in many
respects to gud.a, and may represent a better choice for
people living in temperate climates when consumed in
small amounts, as an anupa-na.
