EXAMINATION
OF FAECES
The state of the faeces is universally
regarded by
many systems of traditional healing including
A¯
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 va칣a,
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 va칣a-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 a칖a.
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
agnima칗dya, 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 mu칣ra
parı칔s
˙
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 va칣a. 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 va칣a. A sense
of rectal fullness and pelvic heaviness
without
bleeding, but with rectal itching is an
indication of
a칖a or kapha. A sense of burning or irritation is
always an indication of pitta, although va칣a is
very often involved, as in fistula-in-ano.
Stool that
has been passed with an explosive force and
much
flatulence is a combined va칣a-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.

of diagnosis, but few modern college-trained
A¯
yurvedic physicians practice it with any
skill, and
as a result its preservation within the
framework of
A¯
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
A¯
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
Na칍
˙
ı칥ij˜na칗am 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 Vai큦es
˙
ika
Su?tra, one of the six
dar큦anas of the Vedas.22 The Na칍
˙
ı칥ijn˜a칗am 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 Na칍
˙
ı칛raka큦am 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
˙
a칗˜ga Guhyaupade큦a
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 anuma칗a, 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 (a칛topade큦a) 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 na칍
˙
ı¯
parı칔s
˙
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 na칍
˙
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 Na칍
˙
ı칥ijn~a칗am, 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) na칍
˙
ı?runs up the right side of
the body, and the ida?(feminine) na칍
˙
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 pra칗.a through the pingala?na칍
˙
ı¯
may be deficient, resulting in a decline in agni. If the
left pulse is weaker, then the flow of pra칗.a through
the ida?na칍
˙
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 va칣a, so an
abnormal pulse rate at either end of the
spectrum, i.e.
fast or slow, can indicate a dysfunction of va칣a.
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 va칣a, such as fear, anxiety
or nervousness. The difference between pitta
or va칣a
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 va칣a, and
a substantial diminishment of the life force
(jı칥a¯). 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).
Ta칕a (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 pra칗
˙
a as it flows through the arteries to
enliven the body. When va칣a is normal the rhythm of
the pulse is regular. When va칣a is in an increased state
the pulse becomes irregular, due to its ‘dry’
(ru칔s
˙
a) and
‘light’ (laghu) properties, making the pulse erratic and
unstable. When the pulse is regularly
irregular both
va칣a and kapha are likely involved, kapha
providing
an element of ‘stability’ (sthira) to the pulse. When the
pulse is irregularly irregular both pitta
and va칣a are
likely to be involved, as the ‘light’ (laghu) properties of
pitta
compound this same quality in va칣a. 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
pra칗
˙
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 va칣a). 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 va칣a).
Gati
(archetype)
The movement of the pulse in na칍
˙
ı?parı칔s
˙
a?is traditionally
ascribed to certain animal archetypes, or
gati. These animal archetypes allow the
practitioner
to visualise factors such as rate (vega), rhythm (ta칕a)
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

124 PART 1: Theory and Practice of A¯ yurveda
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 va칣a 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 Na칍
˙
ı칥ijn~a칗am, 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
va칣a-kapha condition, a frog-snake pulse, indicating a
combined pitta-va칣a condition, a frog-swan pulse
indicating a combined pitta-kapha
condition, or even
all three archetypes, indicating a sannipa칣a condition.
Stha칗a (location)
Each finger that is used to palpate the
artery can be
correlated to a specific dos
˙
a, or more specifically, a particular
stha칗a or region of the body that is ruled by a
specific dos
˙
a (see section 2.4 Stha칗a: residence of the
dos.as). According to the fourth stanza of the
Na칍
˙
ı칥ijn~a칗am, when the practitioner places the
index finger below the thumb (granthi) on the radial
artery, followed by the middle and ring
fingers, ‘first
flows va칣a, 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 Na칍
˙
ı칥ij˜na칗am
the ring finger indicates va칣a, 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 stha칗as ruled by each of the dos
˙
as. Thus:
● The ring finger is an assessment of va칣a stha칗a,
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
stha칗a,
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
stha칗a,
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 va칣a (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 va칣a
(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 stha칗a 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 (da큦avidha parı칔s
˙
a¯) and other examination
techniques (as
˙
t
˙
a칢tha칗a parı칔s
˙
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 stha칗as with
all three fingers you note a particularly
powerful pulsation,
this may indicate a higher metabolic rate
(i.e.

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 stha칗a
is that of a snake (weak, thin and subtle),
this may indicate
a va칣tika 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 na칍
˙
ı¯
parı칔s
˙
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),
ta칕a (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
stha칗a (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?parı칔s
˙
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 va칣a, respectively, so
too can the tongue be divided into three
portions: the
anterior representing kapha
stha칗a, the middle representing
pitta
stha칗a, and the posterior (or root),
representing va칣a stha칗a. As the entire function of
the tongue is controlled by uda칗a va칪u, 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?parı칔s
˙
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 vya칗a va칪u. 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 va칣a, pitta or
kapha. Va칣a 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 va칣a 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, va칣tika
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
pra칗
˙
a in the subtle body, along the same axis as
the
spinal column. Pra칗
˙
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 pra칗
˙
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 pra칗
˙
ic deficiency in the
region of the body that corresponds with the
same
region, or stha칗a 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 dha칣us.
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 va칣a, pitta or
kapha.
Coating
The coating refers to the tongue covering,
also called
the ‘fur’, and relates specifically to the
function of agni
(pa칌aka 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 va칣a any dysfunctional movement is
va칣tika 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
Na칍
˙
ı칥ijn~a칗am is one and the same as the author of the
Vai큦es
˙
ika
Su칣ra. 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 Na칍
˙
ı칥ijn~a칗am 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 Na칍
˙
ı칥ijn~a칗am 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 na칍
˙
ı?parı칔s
˙
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 stha칗as represented by va칣a (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
manda칐ni), 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 va칣a and decreased ojas.
