BharatNotes Key Concepts
- Ayurveda ("science of life" in Sanskrit) is India's classical system of medicine, documented in the three foundational texts: Charaka Samhita, Sushruta Samhita, and Ashtanga Hridayam
- Sushruta is called the "Father of Surgery" — his text describes rhinoplasty, cataract surgery, and over 300 surgical procedures
- The Ministry of AYUSH was established in November 2014 to promote traditional Indian medicine systems
- Relevant for UPSC GS-1 (cultural heritage), GS-2 (health policy, AYUSH), and occasionally GS-4 (ethics of traditional vs. evidence-based medicine)
Core Theory — Tridosha
Ayurveda holds that the human body and all of nature are composed of the Panchamahabhuta (five great elements: earth, water, fire, air, space) and that health depends on the balance of three doshas (bio-energies):
| Dosha | Elements | Governs |
|---|---|---|
| Vata | Air + Space | Movement, nervous system, breathing |
| Pitta | Fire + Water | Digestion, metabolism, intelligence |
| Kapha | Water + Earth | Structure, immunity, lubrication |
Disease arises from imbalance (vikriti) in the doshas relative to one's natural constitution (prakriti).
Charaka Samhita — Internal Medicine
The Charaka Samhita is the foundational text of Ayurvedic internal medicine (kayachikitsa).
| Feature | Detail |
|---|---|
| Original composition | Compiled from the teachings of Punarvasu Atreya by his disciple Agnivesha; then redacted by Charaka |
| Dating | Scholars place it between 100 BCE and 200 CE; the current text was further revised by Dridhabala in the 6th century CE |
| Structure | 8 books (Sthanas), 120 chapters; covers diagnosis, pathology, therapeutics, pharmacology, and medical ethics |
| Focus | Kayachikitsa — internal medicine; also covers diet, rejuvenation therapy (Rasayana), and reproductive health |
| Key contributions | Early understanding of metabolism, digestion, and the concept of agni (digestive fire); detailed pharmacopoeia of medicinal plants |
Sushruta Samhita — Surgery
Sushruta (fl. c. 600 BCE, based in Varanasi) authored the foundational text of Indian surgery.
| Feature | Detail |
|---|---|
| Status | Sushruta is known as the "Father of Surgery" and the "Father of Rhinoplasty" |
| Surgical instruments | Described 120 surgical instruments (shalya yantra) |
| Procedures | Described 300 surgical procedures across 8 categories of surgery |
| Rhinoplasty | Described nasal reconstruction using a flap from the cheek or forehead — a technique still called the "Indian flap" and practiced in modern plastic surgery |
| Cataract surgery | Described "couching" — using a sharp curved needle (jabamukhi shalaka) to displace the clouded lens |
| Other procedures | Hernia repair, bladder stone removal, Caesarean section procedures, eye surgery |
| Anatomy | Conducted cadaver dissection (shava vyavachchheda) for anatomical study — centuries before European anatomy |
Vagbhata and the Ashtanga Hridayam
Vagbhata authored the Ashtanga Hridayam ("Heart of the Eight-Limbed [Medicine]"), broadly dated to the 5th–7th century CE. It synthesised the teachings of Charaka and Sushruta into a concise, systematically organised text.
- Widely considered Ayurveda's greatest classic by number of surviving manuscript copies
- Covers all eight branches of Ayurveda: Kayachikitsa, Balachikitsa, Graha, Urdhvanga, Shalya, Damshra, Jara, and Vrisha
- Vagbhata is believed to have been a Buddhist physician; his text was translated into Tibetan and Arabic, spreading Ayurvedic knowledge across Asia
Nagarjuna and Rasa Shastra
Nagarjuna (c. 8th century CE; distinct from the 2nd-century Buddhist philosopher of the same name) is credited with systematising Rasa Shastra — the branch of Ayurveda dealing with the therapeutic use of purified metals and minerals.
- Rasa (Sanskrit: mercury) is considered the king of metals in Indian alchemy
- Rasa Shastra involves processes of Shodhana (purification) and Marana (calcination) to detoxify metals for medicinal use
- Nagarjuna is called the "Father of Rasashastra"
- Contributed to the preparation of medicinal formulations from mercury, gold, iron, and other minerals
Eight Branches of Ayurveda (Ashtanga Ayurveda)
| Branch | Scope |
|---|---|
| Kayachikitsa | Internal medicine |
| Balachikitsa (Kaumarabhritya) | Paediatrics |
| Graha Chikitsa | Psychiatry and spiritual disorders |
| Urdhvanga Chikitsa | Diseases of ears, eyes, nose, throat |
| Shalya Tantra | Surgery |
| Damstra Chikitsa (Agada Tantra) | Toxicology |
| Jara Chikitsa (Rasayana) | Geriatrics and rejuvenation |
| Vrisha Chikitsa (Vajikarana) | Reproductive health and aphrodisiacs |
AYUSH Ministry and Modern Context
The Ministry of AYUSH (Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homoeopathy) was established on 9 November 2014 — elevated from a Department (which had existed since 2003) to a full-fledged Ministry under the Government of India.
Key developments:
- WHO Traditional Medicine Strategy (2014–2023, followed by 2025–2034) recognises traditional medicine systems including Ayurveda
- India's Traditional Knowledge Digital Library (TKDL) documents traditional Ayurvedic formulations to prevent biopiracy
- The Pharmacopoeia of India and Ayurvedic Pharmacopoeia of India standardise herbal and mineral formulations
- Growing international interest in Ayurveda as part of integrative medicine, though scientific validation of individual treatments remains ongoing
Recent Developments (2024–2026)
WHO Global Centre for Traditional Medicine — Fully Operational from Jamnagar (2024)
The WHO Global Centre for Traditional Medicine (GCTM), established in March 2022 by WHO at Jamnagar, Gujarat with foundational support from the Government of India (total commitment: USD 250 million, including land, premises, and programme funding), reached full operational status in 2024. The Government of India provided 35 acres of land at Jamnagar — within the complex of the Institute for Teaching and Research in Ayurveda (ITRA) — for the Centre's permanent building. GCTM functions as a WHO Headquarters department focused on advancing scientific evidence for traditional and complementary medicine, knowledge exchange, biodiversity conservation, and building global partnerships. WHO published the GCTM Annual Report 2024, documenting its research framework, policy work, and outreach.
The GCTM's significance is historic: it is the world's only WHO-backed global centre for traditional medicine, and its location in India reflects India's position as the world's leading practitioner of multiple codified traditional medicine systems — Ayurveda, Yoga, Naturopathy, Unani, Siddha, and Homeopathy (AYUSH). At the World Health Summit Regional Meeting (April 2025), GCTM participated in a keynote plenary on "scaling up evidence-based traditional medicine." This positions Indian traditional medicine systems as potential contributors to global universal health coverage, particularly for low-resource countries.
UPSC angle: GCTM (Jamnagar, 2022, fully operational 2024) is a high-frequency exam topic at the intersection of India's health policy (AYUSH Ministry, 2014), GS1 cultural heritage (Ayurveda, Charaka, Sushruta), and GS2 international health governance (WHO). The "India funding a WHO global body" dimension is significant for GS2 questions on multilateralism and India's soft power in health diplomacy.
TKDL and Digital Protection of Ayurvedic Knowledge — 2024–25
The Traditional Knowledge Digital Library (TKDL) — developed by CSIR and the Ministry of AYUSH — continued to be India's primary tool for preventing biopiracy of traditional medicinal knowledge in 2024–25. TKDL contains over 10 lakh pages of documented traditional knowledge across Ayurveda, Unani, Siddha, and Yoga in five languages and 122 sub-categories, accessible to international patent offices (EPO, USPTO, JPO) to block fraudulent patents on Indian traditional remedies. The IKS Division's Workshop-8 (August 2025) on "Traditional Knowledge — Intellectual Property and People's Rights" — conducted jointly with CSIR-TKDL — specifically addressed the intersection of ancient medical knowledge, IPR, and community rights.
The Ayurvedic Pharmacopoeia of India (API) continued updating its volumes in 2024–25, standardising formulations of classical Ayurvedic preparations. The National AYUSH Mission (NAM) under the Ministry of AYUSH expanded access to AYUSH services at public health facilities across India, with Ayurveda wellness centres co-located at district hospitals — a convergence of ancient medicine with the modern health infrastructure under the Ayushman Bharat framework.
UPSC angle: TKDL (biopiracy prevention), API standardisation, AYUSH Ministry (2014), and National AYUSH Mission are all GS2 and GS3 topics with strong GS1 cultural heritage roots. For Mains, Ayurveda's contemporary relevance — WHO recognition, GCTM, COVID-era debates — offers rich material for 10-mark and 15-mark answers on India's soft power and health governance.
PYQ Relevance
- UPSC Prelims: "Which of the following is NOT a branch of Ayurveda?", questions on Charaka vs. Sushruta's areas of focus
- Mains GS-1: "Discuss India's ancient medical traditions and their relevance today"
- GS-2: AYUSH policy, integration into mainstream health systems
- Sushruta and rhinoplasty is a commonly cited UPSC fact
Exam Strategy
- Key distinction: Charaka = internal medicine; Sushruta = surgery; Vagbhata = synthesis/compilation
- AYUSH Ministry established 2014, not 2016 — a common factual error in coaching notes
- Sushruta described 120 instruments and 300+ procedures — these exact numbers are tested
- For Mains: Frame Ayurveda as a holistic knowledge system integrating biology, ecology, and medicine — and discuss the challenge of evidence-based validation in the modern context
