Yoga, Ayurveda and the AYUSH Systems: Texts and Facts
Exam notes on the AYUSH systems: Ayurveda, Yoga, Naturopathy, Unani, Siddha, Homoeopathy and Sowa-Rigpa, with founders, classical texts, principles and institutes.
By GK24 Editorial Team· Published · 5 min read

AYUSH is the official name for India's traditional and non-allopathic systems of medicine. The letters stand for Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homoeopathy, and Sowa-Rigpa was recognised as the seventh system in 2010. Examiners return to this chapter every year because almost every fact in it is a pairing that fits in one line: a system with its founder, a text with its author, a system with the language or the region in which it grew. The AYUSH economy is in the news again as fresh studies size India's traditional medicine services in tens of billions of dollars, but the paper asks the lasting facts, and those are what follow.
From a department to a full ministry
A separate Department of Indian Systems of Medicine and Homoeopathy was created in March 1995 to look after these systems, which until then were handled by a cell inside the Ministry of Health and Family Welfare. The department was renamed the Department of AYUSH in November 2003, and on 9 November 2014 it was upgraded into a full Ministry of AYUSH with a minister of its own. The National AYUSH Mission, a centrally sponsored scheme run with the states, dates from the same year. Regulation was recast in 2020, when the National Commission for Indian System of Medicine and the National Commission for Homoeopathy replaced the older Central Council of Indian Medicine and Central Council of Homoeopathy as the statutory regulators of education and practice.
Ayurveda, the science of life
Ayurveda joins ayur, meaning life, with veda, meaning knowledge, and is treated as an upaveda of the Atharvaveda. Its mythic founder is Dhanvantari, the physician of the gods who rose from the churning of the ocean holding the pot of amrita, and Ayurveda Day is kept on his day, Dhanwantari Jayanti, which falls on Dhanteras; it was observed for the first time in 2016. The system rests on the three doshas, Vata, Pitta and Kapha, whose balance is health and whose disturbance is disease, on the seven dhatus or tissues and on the three malas or wastes. Treatment runs from diet and daily regimen to the five cleansing procedures of Panchakarma: Vamana, Virechana, Nasya, Basti and Raktamokshana. Classical Ayurveda has eight branches, which is why it is also called Ashtanga Ayurveda.
Its literature is asked as two sets. The Brihat Trayi, the great triad, is made of the Charaka Samhita, the Sushruta Samhita and Vagbhata's Ashtanga Hridaya. Charaka wrote on internal medicine, Kayachikitsa, and is called the father of Indian medicine; Sushruta wrote on surgery, Shalya Tantra, described the repair of a severed nose and listed scores of surgical instruments, and is called the father of surgery. The Laghu Trayi, the lesser triad, is the Madhava Nidana on diagnosis, the Sharngadhara Samhita on preparations and the Bhavaprakasha of Bhavamishra.
| System | Founder or key figure | Principal text |
|---|---|---|
| Ayurveda | Dhanvantari in tradition; Charaka and Sushruta in practice | Charaka Samhita, Sushruta Samhita |
| Yoga | Patanjali | Yoga Sutras |
| Naturopathy | No single founder; Mahatma Gandhi its best known Indian advocate | Writings on nature cure |
| Unani | Hippocrates, called Buqrat; systematised by Galen, called Jalinoos | Al-Qanun fi al-Tibb of Ibn Sina |
| Siddha | The eighteen Siddhars, Agasthyar held foremost | Siddha treatises in Tamil |
| Homoeopathy | Samuel Hahnemann | Organon of Medicine |
| Sowa-Rigpa | Yuthok Yonten Gonpo in tradition | Gyud-Zhi, the Four Tantras |
Yoga and its eight limbs
Yoga is at once one of the six orthodox schools of Indian philosophy and a practical discipline. Patanjali, called the father of yoga, compiled the Yoga Sutras and set out Ashtanga Yoga, the eight limbs: Yama, Niyama, Asana, Pranayama, Pratyahara, Dharana, Dhyana and Samadhi. The Bhagavad Gita describes yoga as samatvam, evenness of mind, and names the paths of Jnana, Bhakti and Karma yoga, to which Raja yoga is added as a fourth. The later Hatha texts, the Hatha Yoga Pradipika of Swatmarama, the Gheranda Samhita and the Shiva Samhita, give the asanas and the pranayamas, among them Ujjayi, whose sound resembles the sea. The United Nations General Assembly declared 21 June the International Day of Yoga on 11 December 2014 and it was first observed in 2015; UNESCO inscribed yoga on its Representative List of the Intangible Cultural Heritage of Humanity in 2016.
Naturopathy, Unani and Siddha
Naturopathy is a drugless system that treats with the five elements, earth, water, fire, air and space, through diet, fasting, mud packs, hydrotherapy, massage and sunlight, and it had no greater Indian advocate than Mahatma Gandhi. Unani reached India with Arab and Persian scholars about the eleventh century and was patronised by the Delhi Sultanate and the Mughals; its name comes from Yunan, that is Ionia or Greece. Hippocrates, known in Unani as Buqrat, is its founder and Galen, Jalinoos, its systematiser, while Ibn Sina, called Avicenna in Europe, wrote Al-Qanun fi al-Tibb, the Canon of Medicine, and Al-Razi the Kitab al-Mansuri. Unani works with four humours, blood, phlegm, yellow bile and black bile, and with the temperament or mizaj of a patient. Siddha is the oldest of the systems and grew in the Tamil country; it is credited to the eighteen Siddhars, of whom Agasthyar is held the foremost, and it is marked out by its use of metals and minerals in medicine.
Homoeopathy, Sowa-Rigpa and the apex institutes
Homoeopathy was founded by the German physician Samuel Hahnemann, who wrote the Organon of Medicine and laid down the maxim similia similibus curentur, let like be cured by like, along with the law of the minimum dose and the method of potentisation. It reached India in the eighteenth century and took deepest root in Bengal, and World Homoeopathy Day is kept on 10 April, Hahnemann's birthday. Sowa-Rigpa, the science of healing, is the Amchi system of the Himalaya, practised in Ladakh, Lahaul and Spiti, Sikkim, Arunachal Pradesh and the Darjeeling hills; its foundational text is the Gyud-Zhi, the Four Tantras, and Parliament recognised it by law in 2010. The National Institute of Sowa-Rigpa was set up at Leh. The other apex institutes worth memorising are the All India Institute of Ayurveda in New Delhi, the Institute of Teaching and Research in Ayurveda at Jamnagar, the National Institute of Ayurveda at Jaipur, the National Institute of Unani Medicine at Bengaluru, the National Institute of Siddha at Chennai, the National Institute of Homoeopathy at Kolkata, the National Institute of Naturopathy at Pune and the Morarji Desai National Institute of Yoga in New Delhi.
Exam Point of View
Questions come in four shapes. First, the acronym itself: which system is not part of AYUSH, and which was added in 2010, where Sowa-Rigpa is the answer and naturopathy the usual distractor. Second, person with text: Charaka with internal medicine against Sushruta with surgery, Patanjali with the Yoga Sutras against Swatmarama with the Hatha Yoga Pradipika, Hahnemann with the Organon, Ibn Sina with the Canon of Medicine. The Brihat Trayi set against the Laghu Trayi is the hardest of these. Third, dates: 1995, 2003 and 2014 are all offered together for the AYUSH ministry, and 21 June, 10 April and 7 April for the yoga, homoeopathy and health days. Fourth, terms: the three doshas, the five Panchakarma procedures, the eight limbs in order, the four humours of Unani, and the meaning of samatvam. Teaching papers add questions on pranayamas, where Ujjayi is paired with the sound of the sea.

Practice MCQs on this topic
Yoga means?
- A.Just an exercise
- B.a way to distract oneself
- C.an escape from reality
- D.a process for elevating oneself
Show answer
Correct answer: D. a process for elevating oneself
Explanation
The correct answer is D, a process for elevating oneself. The word yoga comes from the Sanskrit root yuj, to join or to yoke, and the classical tradition treats it as a discipline that unites the individual self with the higher self. Patanjali defines it in the Yoga Sutras as the stilling of the modifications of the mind, and the Bhagavad Gita calls it samatvam, evenness of mind; both are descriptions of a person being raised, not entertained. Option A is wrong because physical exercise is only the third of the eight limbs, asana, and yoga also covers ethical conduct, breath control and meditation. Option B is wrong because yoga asks for concentration and inward attention, which is the opposite of distraction. Option C is wrong because yoga trains a practitioner to face life steadily and act without agitation; escape from reality is no part of it.
Yoga means maintaining the evenness of mind which is known as ________ for the efficient performance of work.
- A.karmasukausalam
- B.samatvam
- C.purushav
- D.dukhasamyoga viyoga
Show answer
Correct answer: B. samatvam
Explanation
The correct answer is B, samatvam. Samatvam means equanimity or evenness, the steadiness of mind that is not shaken by success or failure, and the Bhagavad Gita uses the expression samatvam yoga uchyate, evenness of mind is called yoga. A mind in that state works without anxiety, which is why the term is linked with efficient performance of work. Option A is wrong because karmasu kaushalam means skill in action, a result of equanimity rather than the name of the state itself. Option C is wrong because purusha in Samkhya and Yoga philosophy is the conscious self or spirit, not a mental state. Option D is wrong because dukha samyoga viyoga refers to the separation from contact with suffering, a definition of yoga given elsewhere in the Gita but not the word asked for here.
Three model paths to appreciate the spirit are:
- A.karma yoga, chit yoga, bhakti yoga
- B.sat yoga, chit yoga, Ananda yoga
- C.jnana yoga, bhakti yoga and karma yoga
- D.jnana yoga, sat yoga, chit yoga
Show answer
Correct answer: C. jnana yoga, bhakti yoga and karma yoga
Explanation
The correct answer is C, jnana yoga, bhakti yoga and karma yoga. Indian tradition, and the Bhagavad Gita in particular, sets out three classical paths by which a seeker may reach the spirit: jnana yoga, the path of knowledge and discrimination; bhakti yoga, the path of devotion and surrender; and karma yoga, the path of selfless action performed without attachment to its fruit. Raja yoga, the path of meditation taught by Patanjali, is often added as a fourth. Options A, B and D are wrong because sat, chit and ananda are not paths at all; they are the three attributes of the absolute in Vedanta, being, consciousness and bliss, joined in the compound Sachchidananda. The question tests whether a candidate can tell a path of practice from a description of the absolute.
Which pranayama is all about imitating the sound of the sea or waves?
- A.Kapalbhati Pranayama
- B.Shitali Pranayama
- C.Ujjayi Pranayama
- D.Dirgaya pranayama
Show answer
Correct answer: C. Ujjayi Pranayama
Explanation
The correct answer is C, Ujjayi pranayama. In Ujjayi the throat is slightly narrowed while breathing through the nose, so the air makes a soft continuous hiss that is commonly compared with the sound of the sea or of waves; for that reason it is called the ocean breath, and the name itself means victorious. Option A is wrong because Kapalbhati is a rapid cleansing practice in which the exhalation is forced out by drawing in the abdomen, and its sound is a series of sharp puffs, not a steady murmur. Option B is wrong because Shitali is a cooling practice in which the breath is drawn in through a rolled tongue, and its characteristic feature is coolness rather than sound. Option D is wrong because dirgha simply means long or deep breathing and carries no such sound.
Which system of medicine was recognised as the seventh system under AYUSH in 2010?
- A.Naturopathy
- B.Sowa-Rigpa
- C.Homoeopathy
- D.Siddha
Show answer
Correct answer: B. Sowa-Rigpa
Explanation
The correct answer is B, Sowa-Rigpa. Sowa-Rigpa, the science of healing, is the Amchi system of medicine practised in the Himalayan belt of Ladakh, Lahaul and Spiti, Sikkim, Arunachal Pradesh and the Darjeeling hills, and its foundational text is the Gyud-Zhi or Four Tantras. Parliament gave it statutory recognition in 2010 by amending the law governing the central council for Indian medicine, which made it the seventh system in the AYUSH family. Options A, C and D are wrong because naturopathy, homoeopathy and Siddha were all part of the group from the beginning: the acronym AYUSH itself is built from Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homoeopathy. A National Institute of Sowa-Rigpa was later set up at Leh in Ladakh, and the system is also practised across the Himalayan belt of Nepal, Bhutan and Mongolia, which is why it is sometimes described as the Himalayan or Tibetan system of medicine.
Who is regarded as the father of surgery in ancient India?
- A.Charaka
- B.Sushruta
- C.Vagbhata
- D.Bhavamishra
Show answer
Correct answer: B. Sushruta
Explanation
The correct answer is B, Sushruta. The Sushruta Samhita is the classical Indian treatise on Shalya Tantra, surgery, and it describes operations for cataract and for bladder stone, the repair of a severed nose that later writers called rhinoplasty, the eight kinds of surgical procedure and a long list of surgical instruments, which is why Sushruta is titled the father of surgery. Option A is wrong because Charaka wrote the Charaka Samhita on Kayachikitsa, internal medicine, and is called the father of Indian medicine instead. Option C is wrong because Vagbhata wrote the Ashtanga Hridaya and the Ashtanga Sangraha, compendia that summarise both earlier works. Option D is wrong because Bhavamishra wrote the much later Bhavaprakasha, one of the three texts of the Laghu Trayi.
The Yoga Sutras, which set out the eight limbs of yoga, were compiled by
- A.Swatmarama
- B.Gheranda
- C.Patanjali
- D.Kapila
Show answer
Correct answer: C. Patanjali
Explanation
The correct answer is C, Patanjali. Patanjali compiled the Yoga Sutras, the foundational text of the yoga school of Indian philosophy, and in it he lays out Ashtanga Yoga, the eight limbs: Yama, Niyama, Asana, Pranayama, Pratyahara, Dharana, Dhyana and Samadhi. He is for that reason called the father of yoga. Option A is wrong because Swatmarama wrote the Hatha Yoga Pradifika, a much later Hatha text on asanas, pranayamas and mudras. Option B is wrong because Gheranda is the teacher of the Gheranda Samhita, another Hatha manual, which arranges the practice in seven limbs rather than eight. Option D is wrong because Kapila is held to be the founder of the Samkhya school, the philosophical companion of Yoga among the six orthodox systems, and not the author of the Sutras.
The International Day of Yoga is observed every year on
- A.21 March
- B.21 June
- C.10 April
- D.7 April
Show answer
Correct answer: B. 21 June
Explanation
The correct answer is B, 21 June. The United Nations General Assembly adopted a resolution on 11 December 2014 declaring 21 June the International Day of Yoga, and the day was observed for the first time in 2015. The date was chosen because 21 June is the summer solstice, the longest day of the year in the northern hemisphere, a day of special significance in Indian tradition. Option A is wrong because 21 March is the spring equinox and is observed as International Day of Forests and World Poetry Day. Option C is wrong because 10 April is World Homoeopathy Day, kept on the birthday of Samuel Hahnemann. Option D is wrong because 7 April is World Health Day, which marks the founding of the World Health Organization.
Who founded the homoeopathic system of medicine?
- A.Samuel Hahnemann
- B.Ibn Sina
- C.Hippocrates
- D.Edward Jenner
Show answer
Correct answer: A. Samuel Hahnemann
Explanation
The correct answer is A, Samuel Hahnemann. Hahnemann was a German physician who set out the principles of homoeopathy in the Organon of Medicine, chief among them the maxim similia similibus curentur, let like be cured by like, together with the law of the minimum dose and the method of potentisation. World Homoeopathy Day is kept on 10 April, his birthday. Option B is wrong because Ibn Sina, known in Europe as Avicenna, wrote the Unani classic Al-Qanun fi al-Tibb. Option C is wrong because Hippocrates is the founder of the Unani system and is called Buqrat in its literature. Option D is wrong because Edward Jenner developed vaccination against smallpox using cowpox material and is linked with immunology, not with homoeopathy. Homoeopathy reached India in the eighteenth century and took its deepest root in Bengal.
Al-Qanun fi al-Tibb, the Canon of Medicine and a foundational Unani text, was written by
- A.Al-Razi
- B.Ibn Sina
- C.Galen
- D.Hippocrates
Show answer
Correct answer: B. Ibn Sina
Explanation
The correct answer is B, Ibn Sina. Ibn Sina, called Avicenna in Europe, compiled Al-Qanun fi al-Tibb, the Canon of Medicine, which organised the medical knowledge of his age into a single system and was taught in Asian and European schools for centuries; it remains a basic text of Unani medicine. Option A is wrong because Al-Razi, known as Rhazes, wrote the Kitab al-Mansuri and the Kitab al-Hawi, important works but not the Canon. Option C is wrong because Galen, Jalinoos in Unani literature, systematised the theory of the four humours but wrote in Greek and long before the Canon. Option D is wrong because Hippocrates, Buqrat, is honoured as the founder of the system, and the humoral doctrine is traced to him, not this book.
Which group of texts makes up the Brihat Trayi, the great triad of Ayurveda?
- A.Madhava Nidana, Sharngadhara Samhita and Bhavaprakasha
- B.Charaka Samhita, Sushruta Samhita and Ashtanga Hridaya
- C.Yoga Sutras, Gyud-Zhi and Organon of Medicine
- D.Charaka Samhita, Hatha Yoga Pradipika and Bhavaprakasha
Show answer
Correct answer: B. Charaka Samhita, Sushruta Samhita and Ashtanga Hridaya
Explanation
The correct answer is B, Charaka Samhita, Sushruta Samhita and Ashtanga Hridaya. These three are the Brihat Trayi, the great triad of Ayurvedic literature: Charaka on internal medicine, Sushruta on surgery and Vagbhata summarising both in the Ashtanga Hridaya. Option A is wrong because the Madhava Nidana, the Sharngadhara Samhita and the Bhavaprakasha form the Laghu Trayi, the lesser triad, written much later and dealing with diagnosis, pharmaceutical preparations and materia medica. Option C is wrong because those three books belong to three different systems altogether, yoga, Sowa-Rigpa and homoeopathy. Option D is wrong because it mixes one text of the great triad with a Hatha yoga manual and a text of the lesser triad, which is the usual trap in this question. Remember the triads by their authors: Charaka, Sushruta and Vagbhata for the great, Madhavakara, Sharngadhara and Bhavamishra for the lesser.
In which year was AYUSH made a separate ministry of the Government of India?
- A.1995
- B.2003
- C.2014
- D.2020
Show answer
Correct answer: C. 2014
Explanation
The correct answer is C, 2014. The Ministry of AYUSH was created on 9 November 2014 by upgrading the existing department, so that the traditional systems of medicine would have a ministry and a minister of their own. Option A is wrong because 1995 is the year the Department of Indian Systems of Medicine and Homoeopathy was set up in March, the first separate administrative home for these systems. Option B is wrong because 2003 is the year that department was renamed the Department of AYUSH, in November, which created the acronym but not the ministry. Option D is wrong because 2020 is the year the National Commission for Indian System of Medicine and the National Commission for Homoeopathy replaced the older central councils as regulators.
Frequently Asked Questions
What is the full form of AYUSH?
AYUSH stands for Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homoeopathy. Sowa-Rigpa, the Amchi system of the Himalaya, was given statutory recognition in 2010 and is counted as the seventh system, although the acronym was not changed. The Ministry of AYUSH, created on 9 November 2014, looks after all of them.
Who is called the father of Ayurveda?
Tradition names Dhanvantari, the physician of the gods, as the founder of Ayurveda, and Ayurveda Day is observed on Dhanwantari Jayanti, which falls on Dhanteras. Among historical writers, Charaka is called the father of Indian medicine for the Charaka Samhita on internal medicine, while Sushruta is called the father of surgery for the Sushruta Samhita.
Why is 21 June chosen as the International Day of Yoga?
21 June is the summer solstice, the longest day of the year in the northern hemisphere and a date of special significance in Indian tradition. The United Nations General Assembly adopted the resolution on 11 December 2014 and the first International Day of Yoga was observed in 2015.
What is the difference between the Brihat Trayi and the Laghu Trayi?
The Brihat Trayi, or great triad, is the three earliest and most authoritative Ayurvedic works: the Charaka Samhita, the Sushruta Samhita and Vagbhata’s Ashtanga Hridaya. The Laghu Trayi, or lesser triad, is three later works: the Madhava Nidana on diagnosis, the Sharngadhara Samhita on preparations and the Bhavaprakasha of Bhavamishra.
On what principle does homoeopathy work?
Homoeopathy rests on the maxim similia similibus curentur, let like be cured by like, which means that a substance able to produce a set of symptoms in a healthy person can be used in a very small dose to treat similar symptoms in a patient. Samuel Hahnemann set out this principle, with the law of the minimum dose and potentisation, in the Organon of Medicine.
