Ayurveda is a system of medicine with historical roots in the Indian subcontinent. Globalized and modernized practices derived from ayurveda traditions are a type of complementary or alternative medicine. In countries beyond India, Ayurveda therapies and practices have been integrated in general wellness applications and in some cases in medical use.

The main classical ayurveda texts begin with accounts of the transmission of medical knowledge from the gods to the sages and then to human physicians. In Sushruta Samhita  (Sushruta’s compendium), Sushruta wrote that Dhanvantari , Hindu god of ayurveda , incarnated himself as a king of Varanasi  and taught medicine to a group of physicians , including Sushruta. Ayurveda Therapies have varied and evolved over more than two millennia. Therapies are typically based on complex herbal compounds, minerals and metal substances (perhaps under the influence of early Indian alchemy or rasa shastra). Ancient Ayurveda texts also taught surgical techniques, including rhinoplasty, kidney stone extractions , sutures, and the extraction of foreign objects.
