Āyurveda: Ancient India's Complete
Medical System — Since 600 BCE
The word Āyurveda comes from the Sanskrit āyus (life, lifespan) and veda (knowledge). It is the science of life — not just the treatment of disease, but a comprehensive system for understanding how the body works, why it falls ill, and how to live in a way that sustains health across a lifetime.
The three foundational texts — the Charaka Saṃhitā (internal medicine), the Suśruta Saṃhitā (surgery), and Vāgbhaṭa's Aṣṭāṅgahṛdayam — document a medical system of extraordinary sophistication. The Charaka Saṃhitā alone describes 340 plant medicines, 8 animal products, and 64 minerals in clinical detail that remains pharmacologically relevant.
The World Health Organisation (WHO) formally recognises Āyurveda as a traditional medicine system and has collaborated with India on its documentation and standardisation. It is one of the few ancient medical traditions still in active clinical practice today.
The Three Foundational Texts
Charaka Saṃhitā (~600 BCE, compiled ~100 CE)
The definitive text on internal medicine. 8 books, 120 chapters. Describes 340 plant medicines, 8 animal products, and a complete theory of disease causation based on tridoṣa (three constitutional principles). The Charaka Saṃhitā's theory of digestion and metabolism predates European understanding of these processes by nearly 2,000 years.
Suśruta Saṃhitā (~600 BCE text, ~7th century CE compilation)
The foundational text of Āyurvedic surgery. Describes 300+ surgical procedures, 120+ surgical instruments, and the world's first rhinoplasty technique. Suśruta's method for nasal reconstruction was adopted by British surgeons in the 18th century — and is still the basis of modern rhinoplasty.
Aṣṭāṅgahṛdayam — Vāgbhaṭa (~7th century CE)
The synthesis text — condensing Charaka and Suśruta into a concise, complete reference. It became the standard Āyurvedic textbook across India, Tibet, and Central Asia and remains a primary clinical reference in Āyurvedic education.
