Ayurveda the divine science of life







  EXAMINATION
OF FAECES
The state of the faeces is universally regarded by
many systems of traditional healing including
yurveda as the most useful sign in determining
digestive function, and as a result, the health of the
patient. Ideally, the faecal material should be examined
soon after expulsion, in its entirety, and for a
period of several days. This represents some practical
obstacles in a clinical environment, and thus patients
should be instructed as to the method of collecting
data regarding their bowel movements. For certain
diagnostic procedures a small amount of the faecal
material can be collected in a vessel. In a state of
health, a bowel movement will display the following
characteristics:
1. Light brown in colour
2. Solid, well-formed, voided in its entirety without
breaking
3. Have a continuous size and shape, 2.5–4 cm in
diameter
4. Smooth, without a twisted or nodular appearance
5. Without a large degree of undigested food.
There are several criteria when examining the stool:
1. Shape and consistency: When the stool is small,
voided as many pieces, irregularly shaped and has
a marbled appearance, it is an indication of vaa,
dehydration and a lack of both exercise and fibre
in the diet. When the stool is snake-like, having a
small diameter, it is an indication of smooth muscle
spasm, most often a combined vaa-pitta condition.
When the stools are loose to liquid, this is
an increase in pitta, indicating gastrointestinal
irritation or excessive bile excretion. When the
stools are large, dense and mucoid, this is an indication
of kapha.
2. Colour: Blackish stools indicate bleeding in the
upper gastrointestinal tract, or can be from the
excessive consumption of iron. Dark brown stools
can either indicate blood or the presence of aa.
Brown stools are normal. Greenish stools indicate
pitta, from an increase in stomach acidity, gastric
irritation and excess bile. With the use of cholagogues,
however, greenish stools can also indicate
the removal of pitta from the digestive tract
through an increase in liver metabolism and bile.
Whitish stools indicate kapha disorders such as
agnimadya, hepatic torpor, or obstructive
jaundice. Stools are very often coloured by naturally
occurring pigments in the diet, such as the
pink anthocyanins in beets and the orange
carotenes in carrots and yams. As in mura
parıs
˙
a¯, anthraquinone-containing botanicals
(e.g. Rhamnus purshiana) can also colour the faeces
orange or red, and long-term usage may even
temporarily stain the bowel wall, observed on
colonoscopy.
3. Odour: Foul-smelling faeces are related to protein
putrefaction, which is a paittika disturbance, manifesting
as a septic condition of the bowel. This may
also be an indication of jaundice. Milky-smelling
bowel movements indicate the excessive consumption
of refined carbohydrates and dairy, and are
often symptomatic of candidiasis, which is usually
considered to be reflective of a kapha condition.
4. Volume and frequency: A large volume of faecal
material voided more than twice daily is indicative
of paittika tendency. A small volume of faecal
material voided less than once daily is an indication
of vaa. One or two large bowel movements a
day that take much time to void is an indication of
kapha.
5. Symptoms: Rectal bleeding is either an indication
of hepatic portal congestion or from the passing
of excessively dry faecal material. When
concomitant with otherwise normal or liquid
bowel movements it is an indication of pitta,
whereas rectal bleeding concomitant with dry
and rough stool is an indication of vaa. A sense
of rectal fullness and pelvic heaviness without
bleeding, but with rectal itching is an indication of
aa or kapha. A sense of burning or irritation is
always an indication of pitta, although vaa is
very often involved, as in fistula-in-ano. Stool that
has been passed with an explosive force and much
flatulence is a combined vaa-pitta disorder.
Liquid or semi-liquid bowel movements with
blood and a semen-like odour is an indication of
amoebic dysentery, and blood with pus and a fetid
odour is an indication of bacillary dysentery, both
of which are pittaja disorders.

a¯: PULSE DIAGNOSIS
Na
˙
ı?parıs
˙
a?is described as one of the eight methods
of diagnosis, but few modern college-trained
yurvedic physicians practice it with any skill, and
as a result its preservation within the framework of
yurvedic diagnostics can almost be seen as an
anomaly. Traditionally trained A¯ yurvedic physicians
such as those of the as
˙
t
˙
a?vaidya families of Kerala
yurveda, however, claim to posses this knowledge,
but because these techniques are closely guarded
family secrets they remain inaccessible. As a result of
this situation there are a number of different and
widely varying A¯yurvedic pulse techniques promulgated
by various teachers and practitioners, and it is
difficult to determine which are valid and effective.
Many A¯yurvedic physicians consider the
Na
˙
ıij˜naam to be the most authentic text on pulse
diagnosis, written by Mahar
˙
s
˙
i Kanada in about the
3rd century BCE, apparently the same person who
developed the Vaies
˙
ika Su?tra, one of the six
daranas of the Vedas.22 The Na
˙
ıijn˜aam is a
highly detailed text that provides an in-depth knowledge
of the pulses, their qualities and features.
Another important text on pulse diagnosis from the
medieval period is theS큑칞an . gadhara sam
˙
hita¯, which
contains a short treatise on the pulse. More recent is
the Na
˙
ırakaam written by Sankara Sen around
the turn of the last century. These three works form the
primary textual link we have with what is generally
supposed to be an ancient and venerable practice in
India. Beyond these, there are several excellent texts on
pulse diagnosis, such as the Chinese Bin Hu Ma Xue by
Li Shi Zhen (c. 1518 CE; Huynh & Seifert 1981) and
the methods of pulse assessment discussed in the
fourth tantra of Tibetan rGyud bzi (c. 8th century CE;
Finckh 1988), which is stated by some sources to be
a translation of an earlier, now lost, Sanskrit text entitled
the Amr
˙
ta Hr
˙
daya As
˙
t
˙
a˜ga Guhyaupadea
Tantra (Dash 1994). Pulse diagnosis in Chinese and
Tibetan medicine appears to have a longer, continuous
history of use than in India, and as a result they can be
used to confirm and support the practice of pulse diagnosis
in A¯yurveda. Regardless of the methodology,
however, it is always an important thing to realise that
pulse diagnosis is anumaa, an inferential method of
assessment, and in and of itself cannot provide the
practitioner with the exact nature of the patient’s condition:
it always needs to be assessed in conjunction
with the case history (atopadea) and direct observation
(pratyaks
˙
a). This is the skill of the master
clinician – knowing what is relevant and what is
extraneous.
What is the pulse?
Before we begin to delve into the specifics of na
˙
ı¯
parıs
˙
a¯, we need to understand the nature of the
pulse. Place your index finger (not your thumb, which
has its own pulse) over any artery in your body, such as
the carotid or radial pulse. As you feel the pulse it may
occur to you that you are feeling the movement of
blood through the arteries, but in actual fact you are
feeling a peristaltic muscular contraction of the artery
that is initiated by the ventricular contraction of the
heart. The pulse wave is like a long piece of rope
stretched on the ground and flicked: the pulse wave is
the ‘flick’ that can be seen to move down the length of
the rope.
The pulse wave that is initiated in the heart functions
to move the blood to the various regions of the
body, and is thus reflective of the heart, the seat of consciousness.
By pressing down and feeling the pulse
waves you are feeling the nature of your own transient
consciousness. These impulses define who and what
you are at any given moment, and while they change
according to factors such as emotions, activity and
time of day, they also display a pattern that translates
to a more generalised state of consciousness: that
which is manifest as your mind and body. Thus when
we examine the pulse we are examining the nature of
this transient consciousness, and the patterns that are
manifest within it.
Place and time
All the texts on na
˙
ı?suggest that it is best examined
first thing in the morning, sometime after awakening,
and after the elimination of urine and faeces, when the
lethargy of sleep has been cast off. A reading taken
at this time will usually be the most accurate.
Practitioners are advised to avoid reading the pulse
when the patient has just exercised, eaten, been outside
in the cold or warm weather, or just taken a bath
or shower. Pulse diagnosis takes a great deal of concentration
and as a practitioner you should not be hurClinical
examination 121
ried, so take your time when examining the pulse – in
some traditions it would not be uncommon for a practitioner
to patiently observe the pulse for several minutes.
Before taking the pulse ensure that you are not
too tired or hungry, and if you are having some difficulty
concentrating make sure you are breathing
properly. In his insightful book, Secrets of the Pulse,
Vasant Lad recommends silently chanting the syllables
SO upon inhalation, and HAM upon exhalation.
The SO-HAM mantra represents the unity of consciousness
and provides for enhanced concentrative
powers.
Position and pressure
The pulse is generally examined by the index, middle
and ring fingers of the practitioner, with the index finger
positioned just below the styloid process of the
radius, the projection of bone just below the root of
the thumb. Care must be taken not to place the index
finger on the styloid process. In Chinese pulsology the
index and middle fingers are placed above and below
the styloid process, respectively, and this appears to be
another valid way of assessing the pulse – for the purposes
of this text, however, all three fingers must be
placed below the styloid process. In most people the
radial artery is on the same side of the wrist as the
thumb, and it is over this that the three fingers are
placed.
According to the Na
˙
ıijn~aam, the practitioner
uses his or her right hand to assess the pulse of the
right arm of the patient, holding the patient’s hand
with his or her left hand.23 The patient’s palm faces up
and the arm is slightly bent at the elbow. To this end
the patient may rest his or her arm comfortably on
a table (Fig. 10.2A), or the practitioner may support
the weight of the patient’s arm by resting it across
their own arm (Fig. 10.2B). In the rGyud bzi it is said
that the pulse of the right artery is most accurate for
a man, whereas the left artery is more accurate for
a woman. This conforms to the yogic concept that the
pingala?(masculine) na
˙
ı?runs up the right side of
the body, and the ida?(feminine) na
˙
ı?runs up the left
side of the body. Generally speaking, one can use the
left and right pulses to assess the relative balance
between these masculine and feminine qualities in a
given individual. If the right pulse is weaker than the
left, then the flow of pra.a through the pingala?na
˙
ı¯
may be deficient, resulting in a decline in agni. If the
left pulse is weaker, then the flow of pra.a through
the ida?na
˙
ı?may be deficient, resulting in a decline in
ojas.
The palpating fingers should be spaced slightly
apart, and a gentle and uniform pressure should be
applied through the tips of the fingers until pulsation
is felt. When palpating arteries that are covered by
much fat and muscle tissue the third finger may need
to be pressed with greater effort, the second with some
force but less than the third, and the first finger
pressed with the least amount of pressure. The effort
should be made to ensure that the pressure of all three
palpating fingers extends to the same level upon the
radial artery (Fig. 10.2C).
Vega (rate)
Vega is the rate at which the pulse exerts its upward
pressure on the palpating finger, and can be broadly
classified according to each dos
˙
a. This process, like all
movements in the body, is regulated by vaa, so an
abnormal pulse rate at either end of the spectrum, i.e.
fast or slow, can indicate a dysfunction of vaa.
Generally speaking, four pulsations per breath cycle is
considered normal, but this may be faster for children,
a little slower for the elderly. While palpating the
patient’s artery the clinician should simultaneously
observe the patient’s breathing pattern for a few minutes.
If, on average, there are more than four pulsations
per breath cycle, this indicates pitta, suggesting heat,
fever or inflammation. An increase in the pulse rate,
however, may also indicate vaa, such as fear, anxiety
or nervousness. The difference between pitta or vaa
can be understood by noting the gati, or the archetype
of the pulse, described later. Less than four pulsations
may indicate kapha, suggesting heaviness, coldness
and congestion. It may, however, represent vaa, and
a substantial diminishment of the life force (a¯). Once
again, the determination between them is made by
assessing the gati. Sometimes it is difficult to observe
the patient’s breathing pattern, and in such cases the
practitioner measures the rate of pulsation against his
or her own breathing cycle (and hence another requirement
that pulse diagnosis be a meditative exercise).
Taa (rhythm)
The rhythm of the pulse, or the regularity by which
the pulse is felt under the palpating fingers, is an
122 PART 1: Theory and Practice of A¯ yurveda
assessment of pra
˙
a as it flows through the arteries to
enliven the body. When vaa is normal the rhythm of
the pulse is regular. When vaa is in an increased state
the pulse becomes irregular, due to its ‘dry’ (rus
˙
a) and
‘light’ (laghu) properties, making the pulse erratic and
unstable. When the pulse is regularly irregular both
vaa and kapha are likely involved, kapha providing
an element of ‘stability’ (sthira) to the pulse. When the
pulse is irregularly irregular both pitta and vaa are
likely to be involved, as the ‘light’ (laghu) properties of
pitta compound this same quality in vaa. In many
people there may be a transient increase in the heart
rate with inspiration, especially with a deep breath, and
a concomitant transient decrease in the heart rate with
exhalation. This is called sinus arrhythmia, and is found
in healthy adults and is not a sign of a dysfunction.

Clinical examination 123
Bala?(strength)
Bala?is the‘strength’ of the pulse, a measure of the
upward-moving force of the pulse wave under the
three palpating fingers when they compress the artery.
There are three basic levels to the pulse: deep, medial
and superficial. The deep pulse provides indication of
the status of soma, or ojas, the anabolic force of the
body, whereas the superficial pulse corresponds to
tejas or agni, the catabolic force of the body. The
medial pulse exists between these two levels, representing
the communication and relationship between
agni and ojas. The actual pulse wave itself is initiated
pra
˙
a.
One way to conceptualise the difference between
ojas and agni in the pulse is to understand their activities
in the body. Thus, while agni functions to combust
ingested food for bodily usage, its overall activity
is essentially catabolic and eliminative. In contrast,
ojas functions to utilise these nutrients to sustain and
nourish the tissues, and therefore ojas is essentially
anabolic and nutritive.
If the pulse wave is felt strongly when the artery is
palpated superficially, with a light pressure of all three
fingers, and a deep pressure must be exerted to stop
the pulse wave, then the pulse is considered to be
strong, and agni and ojas are more or less equal. In
this case the medial pulse will be similar to both the
superficial and deep pulses.
If the pulse is non-existent or barely palpable in the
superficial position but strong in the deep position,
then agni may be in a weakened state, and the patient
may be suffering from cold and congestion (i.e.
kapha). If the pulse is weak in the superficial position,
and similarly weak in the deep position, both agni and
ojas may be deficient, indicating cold and congestion
with deficiency (kapha and vaa). When the pulse is
strong in the superficial position but disappears when
more pressure is exerted the patient may be suffering
from excess agni (pitta). When the pulse is both
superficial and weak the patient may be suffering from
heat with deficiency (pitta and vaa).
Gati (archetype)
The movement of the pulse in na
˙
ı?parıs
˙
a?is traditionally
ascribed to certain animal archetypes, or
gati. These animal archetypes allow the practitioner
to visualise factors such as rate (vega), rhythm (taa)
and strength (bala¯), along with more specific characteristics
such as the width and volume of the pulse.
Using these animal archetypes it becomes easier to
visualise what dos

primary method to assess the gati is performed by
palpating the artery with all three fingers simultaneously,
pressing down with a medium pressure:
The pulse of vaa is typically described as being that
of a snake sliding along the ground: thin, subtle and
empty. The pulse volume is low and difficult to
detect, slipping and sliding beneath the palpating
fingers.
The pulse of pitta is described as a hopping frog:
wiry, strong and abrupt. The pulse volume is high
and tense, and feels hard and wiry.
The pulse of kapha is described as a swan swimming
through the water: wide, deep, and slippery.
The pulse volume is full, wide and soft, gently rolling
under the palpating fingers.
While there are many more animals archetypes discussed
in the Na
˙
ıijn~aam, such as a leech and elephant
(some of which may even be extinct), the snake,
frog and swan serve as a basic distinction between the
influence of the different dos
˙
as upon the pulse.
Furthermore, it is important to note that these archetypes
may occur in tandem, such that a patient might
display a snake-swan pulse, indicating a combined
vaa-kapha condition, a frog-snake pulse, indicating a
combined pitta-vaa condition, a frog-swan pulse
indicating a combined pitta-kapha condition, or even
all three archetypes, indicating a sannipaa condition.
Sthaa (location)
Each finger that is used to palpate the artery can be
correlated to a specific dos
˙
a, or more specifically, a particular
sthaa or region of the body that is ruled by a
specific dos
˙
a (see section 2.4 Sthaa: residence of the
dos.as). According to the fourth stanza of the
Na
˙
ıijn~aam, when the practitioner places the
index finger below the thumb (granthi) on the radial
artery, followed by the middle and ring fingers, ‘first
flows vaa, the middle is pitta, and last is kapha’.
While some commentators have interpreted it differently,
these explicit instructions appear to indicate that
it is the ring finger that ‘first’ receives the peristaltic
wave of the pulse. Thus, according to the Na
˙
ıij˜naam
the ring finger indicates vaa, the middle finger is
pitta, and the index finger is kapha.24 In my experience
the specific finger does not relate to the quality of
the pulse inasmuch as it relates to the different regions
or sthaas ruled by each of the dos
˙
as. Thus:
The ring finger is an assessment of vaa sthaa,
corresponding to the area located from the umbilicus
downwards (i.e. the colon, adrenals, kidneys,
bladder and reproductive organs).
The middle finger is an assessment of pitta sthaa,
corresponding to the area of the body located
between the umbilicus and the diaphragm (i.e. the
liver, gall-bladder, spleen, pancreas and stomach).
The index finger is an assessment of kapha sthaa,
corresponding to the area located from the
diaphragm upwards (i.e. the lungs, heart and head).
When the right radial pulse is assessed, it may
provide an indication of the health of those tissues and
organs on the right side of the body. Similarly, the left
radial pulse will give an indication of the health of
those tissues and organs on the left side of the body.
Thus the pulse on both wrists divides the body into six
basic regions:
The vaa (ring) pulse felt under the right radial
artery indicates the health of tissues and organs on
the lower right side of the body. Similarly, the vaa
(ring) pulse under the left radial artery indicates the
Vata
Pitta
Kapha
Figure 10.4 Gati: Pulse archetypes
Clinical examination 125
health of tissues and organs on the left side of the
body.
The pitta (middle) pulse under the right radial
artery indicates the health of tissues and organs on
the middle right side of the body. Similarly, the
pitta (middle) pulse under the left radial artery
indicates the health of tissues and organs on the
middle left side of the body
The kapha (index) pulse under the right radial
artery indicates the health of tissues and organs on
the upper right side of the body. Similarly, the
kapha (index) pulse under the left radial artery
indicates the health of tissues and organs on the
upper left side of the body.
Using a moderate pressure, between palpating for
the superficial (agni) and deep (ojas) pulses, palpate
the radial artery simultaneously with all three fingers
and note if the pulsation can be felt under all three. If
the pulsation cannot be felt under any one of the fingers,
the sthaa that corresponds with that finger
may be in a weakened state. Thus, if the right artery is
palpated equally with all three fingers and the pulsation
is weak under the index finger, this may indicate a
dysfunction in the upper part of the body, such as the
right lung or pleura. If the pulse is weak in the middle,
this may relate to a dysfunction of the liver or gallbladder.
If the ring finger pulse is weak, the dysfunction
may lie with the right adrenal, right kidney or
ascending colon. These same inferences can be made
with the left pulse as well. In each case, however, the
practitioner will have to discern what specific tissues
or organs are affected, based on an analysis of the case
history (daavidha parıs
˙
a¯) and other examination
techniques (as
˙
t
˙
athaa parıs
˙
a¯).
If a weakness is noted in any of these three areas
(six locations on two wrists), or even if we want to
obtain more specific information about these areas, we
can use a single finger to palpate each location. Thus if
we want to assess the upper right side of the body, lift
off the middle and ring fingers palpating the right
artery, and simply feel the right pulse with the index
finger. Press down to a deep position with this finger
and note the strength of the pulsation. Now release
this pulse to the superficial position and note the
strength of the pulse. If the pulse is strong in both the
superficial and deep position, the health of the associated
organs and tissues is likely good. If the pulse is
weak in the superficial position then the problem may
rest with the transformative and elimination aspects
(i.e. agni) of the tissues or organ associated with that
area. Thus there may be coldness and congestion in
that part of the body, but the intrinsic health (i.e. ojas)
of the associated organs and tissues may be fine, and
simply needs to be stimulated. If the pulse is weaker in
the deep position, the problem may rest with the
actual health and nutrition of that organ (i.e. ojas),
and there may be a deficiency in that area that
requires treatment. If both the superficial and deep
pulses are weak in that particular location, then both
agni and ojas within that tissue or organ may be in a
debilitated state. If when assessing the sthaas with
all three fingers you note a particularly powerful pulsation,
this may indicate a higher metabolic rate (i.e.

126 PART 1: Theory and Practice of A¯ yurveda
agni) in the associated tissues or organ, at worst, be
suggestive of inflammation.
We can deepen our understanding of these individual
pulse locations by applying our knowledge of gati,
the animal archetypes, to determine the origin or quality
of this dysfunction. Thus, if the pulse in that sthaa
is that of a snake (weak, thin and subtle), this may indicate
a vatika dysfunction in that area. If the pulse is
a frog (wiry, tense and sharp), this may indicates a paittika
dysfunction. If the pulse is a swan (slippery, wide
and soft), this may indicate a kaphaja dysfunction.
Even with this relatively simplified rendering of the
technique there remain many features to na
˙
ı¯
parıs
˙
a¯, and the practitioner must access all of these
features and use them as a collective to accurately
determine the nature of the pulse. To attempt to synthesise
all of these aspects while learning, however,
can be overwhelming. I recommend that practitioners
first become proficient in determing the vega (rate),
taa (rhythm) and bala?(strength) of the pulse. Later
on, add the component of gati (archetype), feeling for
the snake, frog and swan. Once these skills are developed,
begin to incorporate them into the concept of
sthaa (location), determing weaknesses and
strengths in each part of the body, and the specific
characteristics of the pulse wave in each pulse location
that indicates the dos
˙
as and their activities.
10.9 Jivha?parıs
˙
a¯: TONGUE
DIAGNOSIS
The tongue (jivha¯) is perhaps the most useful of the
diagnostic techniques because it is relatively easy to
read, providing detailed information of the state of not
only the gastrointestinal organs, but also the assimilative,
metabolic and circulatory processes of the body.
Full daylight is the best condition in which to examine
the tongue, but otherwise adequate lighting is acceptable.
To examine the tongue properly it should be fully
extended by the patient, but remain relatively relaxed,
without using excessive force which will hide the true
shape of the tongue and make it redder. Ideally, the
tongue should be observed first thing in the morning
before eating, or on an otherwise empty stomach.
Certain foods, including artificially coloured foods,
spices and sweets will change the colour of the coating
on the tongue. Coffee and tobacco smoke will often
leave a yellowish stain on the tongue, whereas pungent
and salty foods like chilies and pickles, and even mouthwash,
will temporarily make the tongue redder.
Further, certain medications will also affect the appearance
of the tongue, such as antibiotics, and may cause
a peeling of the tongue coat or make it thicker.
As with the pulse and the eye, the tongue contains
within itself a map of the whole organism. Just as the
upper, middle and lower portions of the body contain
the function of kapha, pitta and vaa, respectively, so
too can the tongue be divided into three portions: the
anterior representing kapha sthaa, the middle representing
pitta sthaa, and the posterior (or root),
representing vaa sthaa. As the entire function of
the tongue is controlled by udaa vau, specific problems
of the tongue, such as an inability to control
tongue movement, relate to this sub-dos
˙
a. In relation
to specific areas on the tongue, however, certain other
sub-dos
˙
as may be observed as well.
There are five aspects of tongue diagnosis: colour,
shape, location, coating and movement. The following
is an exposition of these five fundamental aspects of
jivha?parıs
˙
a¯:
Colour
This is the colour of the body of the tongue, rather
than its coating, which is discussed later. If the coating
on the tongue is too thick to see underneath it, then
the tongue may be curled up to examine its underside.
The clinical significance of the tongue colour relates to
the state of agni, ojas and vyaa vau. Ideally, the
tongue should have a pinkish vibrancy to it, and any
deviation from this is indicative of imbalance. Once
again, by referring to the tridos
˙
a laks
˙
an
˙
as we can
understand the manifestation of vaa, pitta or
kapha. Vaa will be noticed as a tongue that is dark
red to purplish, bluish, blackish, orange or grey. Pitta
will be seen as a tongue that is bright red or has
a greenish hue. Kapha will be observed as a tongue
that is pale or whitish in colour. Table 10.1 lists the specific
signs to look for in the assessment of the colour of
the tongue.
Readers will note that the tongue of extreme pitta
and extreme vaa are somewhat similar, although
with heat the tongue will be more reddish in colour,
and with cold the tongue will appear more bluish.
Failing the ability to make this distinction, rely upon
techniques such as the pulse, which will be bounding
and rapid with heat, and deep and slow with cold. The
Clinical examination 127
case history will also provide important indications
that can help the practitioner make this distinction.
Shape
This refers to the shape of the tongue, generally, but
including the sides and tip, as well as the surface.
Understanding the shape of the tongue is a differentiation
between thinness and thickness. Examination of
the surface of the tongue means looking for cracking,
furrowing, ulceration, raised papillae, deviation,
swelling, bulging or depressions. Generally, vatika
tongues are thin and short, and may have cracking,
furrowing, deviations, and depressions. Paittika
tongues are typically long and may have raised
papillae and some focal areas of ulceration. Kaphaja
tongues are smooth, thick, flabby and swollen. Table
10.2 differentiates the many shapes that a tongue
may take and the clinical significance of such
findings.
Shape: sides of the tongue
The sides of the tongue (Table 10.3) represent the
assimilative and transformative functions of digestion.
Assimilation is a measure of digestive efficiency, e.g.
the digestive secretions of the lower fundus of the
stomach, small intestine, liver, gall-bladder, and the
exocrine pancreas, all of which are guided by agni.
Transformation on the other hand is a measure of
how these nutrients are converted into the tissues of
the body by the liver. This process is guided by both
agni and ojas.
Shape: tip of the tongue
The very tip of the tongue (Table 10.4) relates to the
function of the heart, and the area just posterior
relates to the lungs. The heart (hr
˙
daya) was traditionally
thought of as the seat of the mind and emotions,
and thus this region refers not only to the
functional heart but also to the brain.

Shape: central axis of tongue
The central axis of the tongue represents the flow of
pra
˙
a in the subtle body, along the same axis as the
spinal column. Pra
˙
a is the animating force in the
body and underlies the function of the central nervous
system. Where a generalised furrow of the tongue can
be seen this may indicate a generalised pra
˙
ic deficiency.
Where the furrow is deviated along the midline
of the tongue, this may indicate a spinal misalignment
or stress in the area of the spine that corresponds with
the region on the tongue (e.g. a cranial, thoracic, lumbar
or sacral misalignment). Where there is a partial
furrow, this may indicate a pra
˙
ic deficiency in the
region of the body that corresponds with the same
region, or sthaa of the tongue.
Shape: surface of the tongue
The tongue is a skeletal muscle covered by a mucous
membrane. The projections on the tongue surface are
called papillae. The majority of the papillae on the
observable tongue are tightly knit filiform papillae,
periodically interspersed with larger fungiform papillae
that contain the taste buds. On the posterior tongue
there is a v-shaped arrangement of circumvallate
papillae that promote the gag-reflex when bitter,
potentially poisonous substances are consumed.
Generally speaking the surface of the tongue represents
the bodily tissues or dhaus.
Location
Location refers to specific areas on the body of the
tongue that can be correlated with certain organ systems.

Clinical examination 129
Signs such as colour, shape, moisture and coating
observed within these locations provide clues as to
how an organ system may be affected by vaa, pitta or
kapha.
Coating
The coating refers to the tongue covering, also called
the ‘fur’, and relates specifically to the function of agni
(paaka pitta). In association with location, however,
the tongue coating will indicate the metabolic function
of that organ system. Tongue coatings are identified by
their color (white, whitish-yellow, yellow, dark yellow,
orange, grey, brown, black), their quality (thin or
thick), and their texture (dry, moist or greasy).
Generally it is better to have a moist tongue than a dry
tongue, and a tongue which changes from moist to dry
indicates a worsening of the condition, while a coating
which changes from dry to moist indicates improvement.
A tongue that changes from a white to yellow
coating indicates that the condition is being driven
from a superficial condition deeper, from congestion
(kapha) to inflammation (pitta), while the reverse
indicates an improving condition, from deeper tissues
to superficial areas for elimination. A coating that

130 PART 1: Theory and Practice of A¯ yurveda
becomes thicker over time indicates a worsening of the
condition, while the reverse indicates improvement.
Table 10.6 provides the clinical significance of each
kind of tongue coating.
Movement
Movement refers to the movement of the tongue when
extended for examination. As the impetus for movement
is primarily vaa any dysfunctional movement is
vatika in origin. Problems with movement include
a shaking or vibrating tongue, a wagging tongue that
moves back and forth, and the inability to extend the
tongue for examination. In this latter case, sometimes
the issue relates to the patient’s discomfort with allowing
their tongue to be examined, and gentle encouragement
may be required. In some cases where the
tongue seems to protrude, this is an indication of
extreme heat (pitta kopa).

ENDNOTES
21 Beverages such as tea, coffee and alcohol, however, can promote
frequency, as will prescription diuretics.
22 There is some scholarly scepticism that the author of the
Na
˙
ıijn~aam is one and the same as the author of the
Vaies
˙
ika Sura. It was not uncommon for medieval writers to
use the name of the great sages to add weight and significance
to their own work, and as a result the Na
˙
ıijn~aam may be
a comparatively more recent text.
23 The rGyud bzi states that the practitioner’s left hand is used to
assess the patient’s right radial artery, in contradiction to what
the Na
˙
ıijn~aam states. Further, some practitioners strongly
suggest that the hand not taking the pulse should not touch the
patient at all, because it will create an electrical circuit which
will lead to an incorrect assessment.
24 This model places the scheme of na
˙
ı?parıs
˙
a?more or less in
line with both Tibetan and Chinese pulsology. Using this model,
it is now possible to understand the correspondences between
the Chinese concept of the san jiao or ‘triple burner’, and the
three sthaas represented by vaa (lower jiao), pitta (middle
jiao) and kapha (upper jiao).
25 It is obvious that the scalloped tongue occurs because the
tongue is either swollen (which indicates kapha, and therefore
mandani), or because the patient unconsciously pushes his or
her tongue against the teeth, causing indentation. This latter
event I believe is an adaptive response to chronic stressors, and
is reflective of vattika conditions. Interestingly, the palate is
considered to be intimately linked to the function of the pancreas
according to A¯yurveda. I have come to suspect that this
thrusting of the tongue upwards against the palate and the
teeth occurs with hypoglycaemic patterns, associated with fight
or flight mechanisms, increased vaa and decreased ojas.
