Contribution of Jaina Literature in the Development of Medical Science: Treatment of Leprosy
By Nagendra Kumar Singh
Summary
In **Contribution of Jaina Literature in the Development of Medical Science: Treatment of Leprosy**, the author surveys how Jain writers contributed to medical science and especially the treatment of leprosy. The *tegicchya* (science of medicine) or *āyurveda* is one of nine sciences recognised in Jain texts. Jaina physicians were versed in eight branches of medicine – pediatrics, surgery and midwifery, ear‑nose‑throat treatments, toxicology, demonology, rejuvenation, sexual rejuvenation and general medicine. Jain scriptures like the *Acaranga Sūtra* list sixteen diseases, including leprosy, consumption, epilepsy, lameness, dropsy, blindness, humpback and diabetes. Treatments were chosen based on the disease and could involve medicated oils (*snehapāṇa*), vomiting, purging, branding, medicated baths, enemas, fumigation, venesection, cutting, scraping or head baths. The *Brhakalpa Sūtra* describes how ascetics afflicted with leprosy and other diseases slept on the skins of vultures, bears or hyenas or applied cow’s urine and other substances to alleviate symptoms. A vivid legend from Hemacandra recounts how physician Jīvananda cured the monk Guṇakara of worm‑infested leprosy by using rare medicines: lakṣapāka oil, gosīrśa‑candana (possibly cow’s bile) and a jewel‑studded blanket (*ratna‑kambala*). Jīvananda bathed the monk in medicated waters and smeared him with the ointments; the worms departed and his skin shone like gold. The author speculates on the identity of these substances and notes that *gorocana*, a yellow bile preparation used as a tilaka, may correspond to gosīrśa‑candana. Commentaries state that the *ratna‑kambala* warms in cold weather and cools in heat. The article concludes by urging Ayurvedic scholars to rediscover lakṣapāka oil for the benefit of humanity and emphasises that Jain physicians followed the principle of non‑violence by giving shelter to worms rather than killing them. This compassionate approach to medicine, combined with sophisticated pharmacological knowledge, underscores the originality of Jain contributions to Indian medical science.
Conclusion
By cataloguing eight branches of medicine and numerous treatments, Jain texts demonstrate a surprisingly advanced understanding of disease and pharmacology. The story of Jīvananda healing Guṇakara highlights both the ingenuity of Jain physicians and their commitment to non‑violence. Although the exact composition of lakṣapāka oil and gosīrśa‑candana remains uncertain, the author shows that these remedies were valued for their efficacy and symbolic purity. The article suggests that recovering such knowledge could enhance modern medicine and that Jainism’s compassion for all living beings shaped its healing practices.
