Ayurgenomics – much ado about nothing !

Recently there has been several write ups in both conventional and social media about a new area of health science research called Ayurgenomics. Ayurgenomics is supposed to help in smoothly integrating tridosha concept of Ayurveda with modern science. There are even claims that tridosha concept has been validated by modern science using genetic studies. Being a science enthusiast and a practicing medical doctor I was deeply interested and decided to have a close look.

What is Ayurgenomics?

The website of India’s Central Government run CSIR-Institute of Genomics & Integrative Biology has a section titled Ayurgenomics. It says :

In Ayurveda texts, though the principles of phenotypes in health and disease states are extremely well described, they are not readily decipherable and hence its potential has not been appreciated by modern genomic researchers. According to Ayurveda individual’s basic constitution (Prakriti) describes its predisposition and prognosis to disease status and also the treatment for disease and lifestyle regime.

In Genomics, individual’s basic constitution is decided by its genetic makeup which indirectly reflects the levels of various biochemical parameters in individual which states its Health status. We aimed at establishment of high correlation of Prakriti with genomic signatures by isolating DNA, RNA and Plasma from the blood sample. It is anticipated that this approach of Ayurgenomics would allow development of surrogate methods for cost effective screening of predisposed individuals in the population. This would result in development of an integrative approach to systems biology for disease and health state.1

The above concept is explained further by Ayurgenomics researchers like this:

The three Doshas, i.e., Vata, Pitta, and Kapha, work in harmony to create a state of good health in an individual while also regulating each other. An individual’s basic constitution, Prakriti, is described to be a consequence of the relative proportion of Vata, Pitta, and Kapha”.

The phenotypic diversity in a population, according to Ayurveda, is a consequence of a continuum of relative proportions of Doshas. Although no two individuals can be identical, ancient texts have categorized the baseline phenotypic variability into seven possible constitutional types, namely, Vataja (V), Pittaja (P), Kaphaja (K), Vata-Pittaja (VP), Pitta-Kaphaja (PK), Vata- Kaphaja (VK), and Vata-Pitta-Kaphaja (VPK). Among these, the first three, which have predominance of one of the three doshas, are considered as extremes, exhibiting readily recognizable phenotypes, and are more predisposed to specific diseases.2

In a more simple language this concept of Ayurgenomics can be explained like this. Ayurveda is supposed to divide normal healthy people according to predominance of doshas. It is supposed to determine three things in an individual:

  1. predisposition to diseases
  2. Prognosis if having a disease and
  3. treatment response

Genetics has determined that a person’s body constitution is decided by the genetic makeup. Ayurgenomics aim to show high correlation between genetic factors and Prakriti system of classification of people and thus they claim it will validate the Ayurvedic concept. This they hope will help in finding markers for cost effective screening of individuals predisposed to certain diseases. They also hope to find easy methods to know which type of patients will respond to different types of therapies.

Before we go deep into these claims, let us see what is this Prakriti system of classification.

Tridosha and Prakriti

The central concept of Ayurvedic medicine is the theory that health exists when there is a balance between three fundamental bodily humours or doshas called Vata, Pitta and Kapha. Together these three doshas determine the physiological balance and constitution of the individual which is called as Prakriti in Ayurveda.

But can a person with a loss of balance between doshas be called normal individual?

According to Charaka Samhita if a person is having predominance of one dosha it is unnatural and hence the word prakriti cannot be used. At the same time the Samhita is also mentioning some other physicians who think it can be used:

Some say “there are no persons having all the 3 doshas in equilibrium because of the use of unbalanced food, thus some are having Vata constitution, some Pitta constitution and others Kapha constitution.”

This statement not correct. Why? Because the physicians take the person having balanced V, P and K as healthy, health is normalcy and for the same object therapeutic measures are applied. Hence there are (person having prakrti as) balanced V, P and K but there are no prakrtis (constitution) like V, P or K. Because of predominance of certain dosha in person the respective dosha prakrti of the same is said, but as there can’t be normalcy in imbalanced doshas they can’t be taken as prakrti. The concerned person can only be said as Vattala, Pittala or Kaphaja because they are in the state of abnormalcy.”3

Thus it seems Ayurgenomics researchers are in a way going against the principles expounded by Charaka Samhita .

Prakriti classification in Ayurvedic texts

Ayurveda texts classify vata, pitta and kapha predominant body constitution using a lot of parameters. (See figure below)4

Table 1: Distinguishing features of individuals of three contrasting Prakriti types Vata, Pitta and Kapha and their disease predisposition as described in the original text.

We can see that almost all the features mentioned for classification of humans into vata, pitta and kapha Prakriti are vague and subjective .

Prakriti in Ayurgenomics studies

Since ancient text books were very vague and subjective I was very much interested in finding out how Ayurgenomics researchers determined Prakriti in an objective manner suitable for modern day research. All the papers on the subject has mentioned that Prakriti was determined by Ayusoft software and/or examination by experienced senior Ayurvedic doctors. Both the software and clinicians relied on a set of questions. Following is an example of such a set of questions used for all studies in Ayurgenomics.5

A. Anatomical FeaturesA. Anatomical Features (cont) and B. Physiological Functions

When we look closely at the set of questions used to classify people to different prakritis, we realise that most of them are very subjective and the answers may depend on the whims and fancies of the interviewer or interviewee.

As no values are given that can define terms, how can one objectively say whether the person examined is proportionate/disproportionate, has symmetry/asymmetry, has skin thick/thin etc? How are terms like healing power, memorising, recalling, digestive power etc defined? How to differentiate between deep and sound sleep, regular and irregular thirst etc are anybody’s guess. This method of Prakriti classification by such set of questions used in a series of widely publicised Ayurgenomics studies can only be called highly subjective with very low chance of repeatability.

Low chance of repeatability

This low chance of repeatability was proved by their own studies. In the paper titled Genome-wide analysis correlates Ayurveda Prakriti6 they tried to get healthy adult males between 20-30 years with 60% predominance of one dosha and concordance through 3 stages of analysis by 3 different analysts. Out of 3416 males studied they could get such a concordance only in 971 persons (28%).

Omission of females

The GWAS paper mentioned above did not include females. The authors explain why women were not included like this:

we have excluded female subjects from this study to minimize the confounding variations. …….. hormonal fluctuations result in numerous physical and psychological disturbances, which occur in the premenstrual and menstrual phases. These elicitable and visible features can confound or obscure the Prakriti assessment process.

Then why women who are not in premenstrual or menstrual phase were not included? Authors give a silly and very conservative explanation, not at all apt for scientific research:

Although the Ayurvedic physicians routinely enquire about the menstrual habits of patients while assessing the Prakriti, it would have been difficult for us to make similar enquiries to young, healthy women who volunteered to join this study

Actually the omission of females was deliberate because it was still difficult to get concordance and significant results because of their experience in an earlier study7. Thus when females are excluded only about 14% of general population had a predominance of one Prakriti and concordance with all investigators.

Can a study which represents just 14% of general population determine surrogate methods for cost effective screening of predisposed individuals in the population?

Prakriti disease predisposition and prognosis

The notion that Prakriti system of classification can determine predisposition and prognosis to disease status and also the treatment for disease and lifestyle regime is just a hypothesis. Nobody has proved that hypothesis yet though it is easily testable.

When I looked through the Ayurgenomics studies, I saw that one of the study actually tested that hypothesis.

In the paper titled Potential of Ayurgenomics Approach in Complex Trait Research: Leads from a Pilot Study on Rheumatoid Arthritis8 they had compared the incidence of Rheumatoid arthritis in people with different Prakritis determined by the above set of questions. They found that 86% of those with Rheumatoid Arthritis had either pitta or kapha Prakriti. People with vata prakrthi seems to have the least predilection for Ama vata (Rheumatoid Arthritis). This is in stark contrast to the claim in classic Ayurvedic texts that Ama vata is more common is vata Prakriti group.

Thus it seems at least this study as a part of Ayurgenomics disproves the claims of tridosha hypothesis.

Does Ayurgenomics validate tridosha hypothesis?

So does Ayurgenomics integrate tridosha concept of Ayurveda with that of modern science?

The answer has to be no as the hypothesis of relationship between tri doshas and diseases is yet to be proven to be true.

What are these doshas? In which part of the body and in what form it exists? How it can be quantified? No answers has come out. The tragedy is nobody is doing any study to prove or disprove it.

Pitta and metabolism – grasping at straws?

The authors of the study Genome-wide analysis correlates Ayurveda Prakriti, claim that:

We found PGM1 gene associated with the Pitta phenotype. In Ayurveda, characteristics of Pitta include digestion, metabolism and energy production. Interestingly, we found PGM1 gene is in the center of many metabolic pathways i.e. glycolysis or gluconeogenesis (hsa00010); pentose phosphate pathway (hsa00030); galactose metabolism (hsa00052); purine metabolism (hsa00230) and; starch and sucrose metabolism (hsa00500) (Figure S7). Our finding suggests that the function of the gene directly correlates with the role of Pitta in metabolism as described in Ayurvedic literature.6

They conclude in the abstract of the paper like this:

Subsequently, we found that PGM1 correlates with phenotype of Pitta as described in the ancient text of Caraka Samhita, suggesting that the phenotypic classification of India’s traditional medicine has a genetic basis; and its Prakriti-based practice in vogue for many centuries resonates with personalized medicine.

This is a grossly false statement. Author of the ancient text Caraka Samhita do not know what is PGM1. So how can that text say PGM1 correlates with Pitta?

As per Charaka Samhita the function of Pitta are:

“vision, digestion, heat, hunger, thirst, softness in body, complexion, lustre, cheerfulness and intellect prowess, exhilaration, clarity9

As per that ancient text the diseases of alimentary canal correlating with excess of pitta are:

hyper- acidity, burning in the stomach and esophagus, internal burning, burning in scapular region, foul smell in body,, jaundice, bitterness in mouth, bloody smell from mouth, foetid smell from mouth, excessive thirst, loss of contentment, stomatitis, inflammation in throat etc10

There is no mention that Pitta is associated with metabolism. Pitta was supposed to be associated with digestion but that is an entirely different process . To say that the vague mention of heat correlates with metabolism is an over-reading. Also among the organs where Pitta is supposed to be located liver, the prime organ of metabolism is never mentioned.

So how can the authors claim that “Our finding suggests that the function of the gene directly correlates with the role of Pitta in metabolism as described in Ayurvedic literature“?

Does Ayurgenomics prove anything?

So what did all those studies on Ayurgenomics did prove?

They have shown that there is an association between presence of certain single nucleotide polymorphisms (minor changes in genes ) and a person ‘s phenotype. A phenotype is the composite of an organism’s observable characteristics or traits. A phenotype results from the expression of an organism’s genes as well as the influence of environmental factors and the interactions between the two. So the fact they have shown, the changes in genes (SNPs ) influence a person’s phenotype, is well known to science.

Will it help in finding markers for cost effective screening of individuals predisposed to certain diseases? For that it has to be proved that people of certain prakrthi (body constitution ) is predisposed to certain diseases. Say for example excess of pitta is supposed to produced hyper acidity . So we can compare people who are supposed to have pitta predominance and those who do not have pitta predominance and find out the level of Hydrochloric acid in stomach and the incidence of peptic ulcer . If a correlation was found it has to be repeated a few times in different settings to really prove the correlation. Without proving it there is no point in thinking about cost effective screening for markers.

A bigger problem in such a research is the difficulty to find out objectively those people with pitta predominance. The repeatability of dividing people into three prakrthi types using the subjective questionnaire used in Ayurgenomics study is questionable . The authors could get a consensus on prakrthi predominance only in about 14% of population they studied.


The Indian government funded Ayurgenomics studies are based on weak science. No attempt is being made to know about the structure, site of occurrence, properties of doshas that are supposed to determine health and diseases. No attempt is being made to prove the primary hypothesis of Prakriti concept that excess of certain doshas produces certain diseases. They are not trying to come out with an objective tool for measuring the prakriti.The fact that genotype influences phenotype is not a new discovery and do not add anything to science. The whole exercise can be considered as a part of a hyper nationalist revivalist agenda to confuse people so as to make it appear that ancient Indian Ayurvedic concepts are based on Science.

About the author

Arun N.M.

I am a skeptic , humanist and feminist. I am an MD in Internal Medicine practicing in Kerala.


  • Thank you Sir, Your article is highly informative.

    When I begin to saw the related news published in different print medias simply stating that Ayurvedic concepts are proven by scientific community, I was little bit confused. Now your article has shed some light on the problem.

    Sir,let me to ask you few small doubts. Is there any scale of reference to classify the different “Prakriti” ? If not what will bd the ultimate result of this research?

    Is there any official criteria for accepting / endorsing a research paper by scientific community? Sorry for asking I have only very little knowledge in this areas.

    • As far as I know , no one has formulated an objective way to classify people into those with dominance of different Prakritis.
      Each journal will have their own criteria for accepting and rejecting papers. This paper though published , is highly unlikely to be accepted by scientific community.

      • Fine, Thank you for the response. In short what I understood is , the classification of different Prakritis is absolutely based of the observers discretion.

  • In the section titled ‘Prakriti disease predisposition and prognosis’, you claim the following:

    //This is in stark contrast to the claim in classic Ayurvedic texts that Ama vata is more common is vata Prakriti group.//

    Could you provide a citation to some of these classic ayurvedic texts? I was unable to find it anywhere 🙁 I wish to clarify this part myself.

    I know this is not a full-blown journal paper where detailed citations are expected, however, this particular statement stands meaningless without them. Hope you understand.

  • Hi I believe there is some confusion in asserting vaata prakriti in predisposing factor in coursing aamavatha . aamavata does not come under vaata vyadhi . so nothing to do with vaata prakrithi and vaatavriddi .aamavaata simply is disease caused by aama .were any metabolic abnormalities or call as indigestion and that conditions and products are taken to diff parts of body by vaata dosha .vaata by quality is mobility and it moves a am a to joints .then produce pain and inflammation . hence the first line of treatment will be a am a pachana or correct digestion both in g I as well as metabolic .then for vaataja symptoms.

    • After describing how ama is produced , the classic text on Amavata goes on to say like this:
      Then it (ama) is absorbed in the system and is taken up by aggravated and vitiated Vayu, especially to Kaphasathanas mainly amasaya , sandhi, uras, Kantha etc and enters the Dhamani by circulation with the help of Vata.
      …….So both Ama and Vata aggravates simultaneously and enters Kostha , Trika and Sandhi and ultimately leads to stabdhata in the body. This is called Amavata.
      (From Madava Nidana 24/2-5 )

      See this journal article written by faculty from BHU , Varanasi :

      “According to Ayurveda each person is born with a unique “Prakriti” or body-mind type. This is based upon unique combination of three bio-principles called Doshas viz. Vata, Pitta, and Kapha. People with predominant Vata or Kapha Prakriti and/or their disequilibrium are more likely to suffer from Aamavata/RA.

      Basisht GK, Singh RH, Chandola H. Management of rheumatoid arthritis (Aamavata) using symbiohealth healthcare system. Ayu. 2012;33(4):466-474. doi:10.4103/0974-8520.110513.

      But in the Ayurgenomics study quoted in my article around majority of RA patients were of Pitta prakrthi.

  • I’ve read your article, research papers referenced on your article and available ayurveda texts

    first of all the papers cited by you was published by various groups of scientists, only one commonality is they worked on prakriti or constitution

    Different group of scientist arrived to common conclusion i.e. possibility of classifying people based on subjective questionnaire, whats wrong in this

    Subjective not objective
    I see same problem in modern medical science for ex;- pain is not quantified, dream is not quantified, moreover psychological concepts like mind, consciousness etc are not yet studied objectively or if you know any objective method to study the parameters mentioned in the papers cited by you, kindly post it.

    Caraka, galen, aristotle etc statements are to be considered as anecdotal evidences, i don’t know why you are bothering it now, concept of prakriti says people born with different proportion of Vata, pitta and kapha, so on the basis of proportion of doshas prakriti is further diveded into 7 types and caraka argues that only pure prakriti should be called as vatala, pittala and kaphala, balanced means having inborn proportion of dosha level and any deviation is considered as disease.

    we can’t judge repeatability by concordance only, in all studies you referenced predominant prakriti is more or less 20% only, it is a scientific fact.

    can u elaborate your understanding of tridosa hypothesis?

    “So the fact they have shown, the changes in genes (SNPs ) influence a person’s phenotype, is well known to science”

    after human genome project, why scientists are finding difficulties in classifying people on the basis of SNPs, also relation of SNPs and phenotype is not straight, may be you have much exposure in this could you please provide the known SNP variation for Hypertension phenotype or simply blood pressure for healthy individuals.

    “The answer has to be no as the hypothesis of relationship between tri doshas and diseases is yet to be proven to be true”

    “What are these doshas? In which part of the body and in what form it exists? How it can be quantified? No answers has come out. The tragedy is nobody is doing any study to prove or disprove it”

    “Will it help in finding markers for cost effective screening of individuals predisposed to certain diseases? For that it has to be proved that people of certain prakrthi (body constitution ) is predisposed to certain diseases”

    for your above three comments i like to answer here

    tridoshas and diseases – all the papers cited by you are finding relation of prakrithi with molecular biology in healthy and one disease, they are not tried to see tridoshas and diseases, you may expect many but authors research was this only

    None of the papers looked into tridoshas, all papers are finding correlation of prakriti and molecular biology not tridoshas and molecular biology, if you clarify your understanding of tridoshas and prakriti would be better

    Dosa predominance and disease- i agree to your point, all cant be done in same time period, scientists work on pre-set goals in timely manner, wait for future publications and also you cant expect everything in a single research paper – you are expecting cell biology, molecular biology, disease in a large number of population sets, show a single paper of this kind.

    Don’t expect cell biology in particle physics

    CONCLUSION – this article is written without understanding basic theories of ayurveda, though author claims. I see more skepticism and criticism rather rationalism, modern science doctors more skeptical towards AYUSH and research in but not on their unproductive, plagiaristic, academic promotional research. So overall this is a biased view not a rationalist view.

  • First you understand what is Tridosha sidhantha and Tridosha prakruthi. Please understand, Vata Pitta and Kapha have no physical existance. They are collective term used to describe a group of physical qualities. Like using the term ‘Vehicle’ collectively to describe bus, car, bike etc. U are beleiving the british method is always scientific. Who said it? They said it and you people are repeating blindly. Dr. C.K Ramachandran, Dr. M.S. Valyathan , Dr. B.M.Hegde etc are telling Ayurveda is scientific. Are they mad? They do understand the basic theory. That is the difference

  • @Dr. Ameer Ayurlokam
    Please tell me which Ayurvedic text speaks of Tridosha as only a theory? Cite actual text, not your interpretations. Where is it written in Ayurveda that “Vata Pitta and Kapha have no physical existence”?

    We are talking about texts which say that they are divine dictations, that gods help curing diseases, demons caused medical events, that mantras are powerful medicines and about how to address heavenly serpents which poison you by just looking at you. Is this what you call a science? Have you ever opened a single Ayurvedic text? Cite some material that demonstrates that anything resembling science was done.

    Please read about Humoral medicine. Humoral theory (the dosha stuff) is not at all unique to Ayurveda. The West also had their own “Ayurveda” – please refer to Galenic and Hippocratic corpora. They all had their vaata, pitta and kapha. Ayurveda is simply the Indian variation of the widely used, pre-scientific system that was followed nearly everywhere.

    As the scientific method began to develop, the West realized that the old texts were horribly flawed and moved on. We in India, have not reached that stage yet. Even people with doctorates don’t always have foundational understanding of sciences.

    Science is not “British”. In the modern world – Science is science, just as physics is physics. There is no Indian physics or British physics. Same with medicine. There is however the contrast between bronze age medicine vs. modern medicine. That is the tension here, not India vs. West. Don’t turn science into a culture war.

    Yes, B.M Hegde is in fact famously unscientific. There are several articles on this website on his pseudoscience. I don’t think I ever heard B.M Hegde say that ANY system of medicine is not scientific. Every pseudoscience is scientific for him, even Homeopathy (German pseudoscience which we now follow more than Germans – do your West battles here) and Reiki (Japanese pseudoscience). He is happily pandering to the uninformed crowd and is a poor example of what a public intellectual should be doing. AFAIK, India does not have any genuine medical intellectuals of global standing. The local stars say a lot of silly stuff, the minute they step outside their area of training and specialization.

  • I am very happy to read something like this. I must congratulate the writer for their courage! In these days, anything which does not fit ayurvedic concepts is considered as against ayurveda and those people are ready to fight and they start lot of mud throwing. Ayurvedic people are most hostile people and they can get angry at almost any logical thing. They only want money and their dukandari to continue. They have nothing to do with patients. They are happy playing their lame arguments. May god bless them.

  • Dr. Arun , I am also an agnostic and a lover of medicine and science.If we deny the efficacy of the questions that are used by the software and ayurvedic clinicians to make their pt classification into various class in this study that is published in a reputed journal like Nature which has an impact factor that is not so bad. I think we have to be very objective in our criticism.
    Following are the elements / questions used by the study software and clinicians involved , which I assume even the modern medicine clinicians also use in their day to day practice.Not to make any general classification or categorization of patients but to make specif diagnosis or to develop DDx.
    correct me if I am wrong.
    If similar set of questions asked to a large group of subjects as seen in this study and that finally led into a random classification of them into three class ( Kapha, vadha, Pitha) on the basis of statistically significant genetic phenotypig which correlates to said classification. what is the rationale for negatively criticizing this study. This study has limitations that is true. which is there for all research in all area. In modern medicine if we plunge into literature we can find many. Let Ayurveda also understand to what extend they are scientific and not. So that people may benefit.
    Here are the element/ questions of the study software and questionnaire used by clinicians in this study. Which are also used by modern medicine clinicians also in day to day practice to find diagnostic clues and even Dx. I put them below with a few examples. so why should we say these questions are subjective and junk when in reality their use ( subjectively) by clinicians in modern medicine also yielding useful results?
    Anatomical Features ( clinical suspicion could be made if other clinical signs and symptoms are present)
    Height- Marfan syndrome,metatropic dysplasia all though rare could be suspected in a pt with relevant family history and other associated clinical evidence.
    Body frame- Kallmann syndrome and idiopathic hypogonadotropic hypogonadism, Cushing syndrome all though rare could be suspected in a pt with relevant family history and other associated clinical evidence.
    Head, forehead , face, eyes and lips – Lots of clinical suspicions could be made for instance, Graves disease ( eyes), Wilson disease (eyes), Argyll Robertson pupil (eyes) to develop suspicion for diabetic neuropathy, Neurosyphilis etc. Bells palsy ( Face), Horner’s syndrome ( Face and eyes) to suspect MS, Brain tumors,Syringomyelia etc. Frontal boosing ( Forehead) – may raise many clinical suspicions ranging from congenital syphilis to Rickets. Oral and lip ecchymosis may lead to clinical suspicions of hemorrhagic diathesis and may be seen in pt under anticoagulants ( Burket’s oral medicine P- 123 Para-2).
    Jaws- acromegaly , mandibular hypoplasia or strawberry chin maybe seen in rare conditions like Catel–Manzke syndrome, Cri du chat syndrome etc.

    chest and shoulder- Polands syndrome can be diagnosed seeing an absence of a pectoralis major. pectus excavetum in the relevant clinical context could raise suspicion of Noonan syndrome, Loeys-Dietz syndrome, even seen in Marfan syndrome too. (Creswick HA1 et all in Journal of pediatric surgery Oct. 2006)

    Hand, Palm, Nails- lot of diagnosis suspicions and even diagnosis could be made for instance – Heberdens and Buchards nods on hand ( anatomical hand) could lead to diagnosis of RA, nails could raise lot of diagnostic suspicions example – Koilonychia could develop diagnostic suspicion for hypochromic anemia , Plumer – Wilson syndrome etc. onychomycosis is another.
    Palms – hyperhydrosis , Raynaud’s disease even soles can sometimes show it.
    legs, soles and joints- various joint edemas could lead to range of diagnostic suspicions ranging form cardiovascular conditions to renal conditions the shape of legs could and foot could lead to lot of clinical suspicions eg- inverted champagne bottle sign could develop clinical suspicion of CMT, pes cavus and pes planus also maybe seen in this condition.

    If I keep typing there can be a big list. appetite, thirst, quality of sleep, skin color , texture and the body odder etc. could lead to many other diagnostic suspicions also. anorexia nervosa( Lack of appetite – has lot of differentials ranging from colitis to cancer, PANDAS all though rare to even hypocalcinosis.

    Polydipsia, Hyperdipsia (thirst) etc.- could lead to lot of diagnostic suspicions such as diabetes insipidus, SIADH, Pseudohyponatremia etc. to even hyperglycemia.

    Quality of sleep- is a clinical diagnostic question in many neuro-psychiatric conditions.

    Skin – is an organ need not require any explanation that its abnormalities could shed light into many systemic and dermal conditions.
