The सुश्रुत संहिता(c. 600 BCE) is the world's oldest surgical treatise. Recognized by the WHO as the “Father of Surgery,” Sushruta documented eight categories of operations — excision, incision, scraping, puncturing, probing, extraction, drainage, and suturing.
Students trained on practice models: lotus stalks for veins, watermelons for tumors, leather bags for abdominal operations, and dead animals before progressing to cadavers. Below are eight landmark procedures.
Rhinoplasty
नासिकासन्धान
Forehead-flap nose reconstruction — the "Indian method" brought to Europe in 1794. First documented plastic surgery.
Cataract Surgery
लिङ्गनाश चिकित्सा
Couching with curved Jabamukhi Salaka needle. Technique spread via Silk Road to Arabia and Europe.
Cesarean Section
गर्भोद्धरण
Described in Sushruta Samhita for obstructed labor. Precise incision and suturing protocols.
Lithotomy
अश्मरी चिकित्सा
Bladder stone removal through perineal incision. Pre-operative diet and post-operative care documented.
Dental Extraction
दन्तशूल चिकित्सा
Over 20 dental conditions classified. Extraction using specialized forceps (dantashanku).
Fracture Setting
भग्न चिकित्सा
12 types of fractures classified. Bamboo splints, bandaging techniques, and traction described.
Prosthetics
कृत्रिम अंग
Artificial legs, noses, and earlobes crafted from wax, clay, and metals. Earliest prosthetic records.
Wound Suturing
सीव्य कर्म
Silk thread, horse hair, bark fibers for sutures. Ant-head sutures for intestinal wounds (natural staples).
Sushruta described 101 blunt and 20 sharp instruments, crafted from iron and steel with specific designs for specific procedures. Many resemble their modern counterparts to a striking degree.

The चरक संहिता (c. 300 BCE) is the foundational text of Ayurveda. Charaka established the concept of त्रिदोष (tridosha) — three biological humors whose balance determines health.
His emphasis on prevention, patient history, clinical examination, and individualized treatment anticipates core principles of modern evidence-based medicine by over 2,000 years.
Three Doshas
वात, पित्त, कफ
Vata (air+space) governs movement, Pitta (fire+water) governs metabolism, Kapha (earth+water) governs structure. Disease arises from imbalance; treatment restores equilibrium through diet, lifestyle, herbs, and detoxification.
Agni (Digestion)
अग्नि
Charaka identified 13 types of digestive fire (agni). He stated that all disease begins in the gut — a principle validated by modern microbiome research linking gut health to immunity, mood, and chronic disease.
Vyadhikshamatva (Immunity)
व्याधिक्षमत्व
Charaka described innate immunity (sahaja), acquired immunity (yuktikrit), and the role of ojas (vital essence) in disease resistance. He cataloged 700+ medicinal plants to strengthen immune response.
Sushruta identified 7 distinct layers of skin through cadaver dissection — a feat of anatomical precision. Modern histology confirms a remarkably similar layered structure.
| Layer # | Vedic Name | Modern Equivalent | Function |
|---|---|---|---|
| 1 | Avabhasini | Stratum Corneum | Outermost protective barrier, reflects complexion |
| 2 | Lohita | Stratum Lucidum | Blood-rich layer, gives skin its color |
| 3 | Shweta | Stratum Granulosum | White layer, related to skin diseases |
| 4 | Tamra | Stratum Spinosum | Copper layer, supports immune function |
| 5 | Vedini | Stratum Basale | Sensory layer, pain perception |
| 6 | Rohini | Dermis | Regenerative layer, wound healing |
| 7 | Mamsadhara | Subcutaneous tissue | Deepest layer, connects skin to muscle |

Sushruta's Oath (~600 BCE)
“You shall devote yourself to helping the sick, even at the cost of your own life. You shall not betray patients even at the cost of your own life. You shall be modest in your dressing and not drink intoxicants. You shall be truthful, calm, and always strive to improve your knowledge.”
Sushruta Samhita, Sutra Sthana, Chapter 2
Hippocratic Oath (~400 BCE)
“I will use treatment to help the sick according to my ability and judgment, but never with a view to injury and wrong-doing. I will keep pure and holy both my life and my art.”
Attributed to Hippocrates, c. 400 BCE
Sushruta's oath predates the Hippocratic oath by approximately 200 years. Both emphasize patient welfare, ethical conduct, and continuous learning — the universal foundations of medical practice.
