Yunani or Unani medicine (Urdu: طب یونانی tibb yūnānī) is the term for Perso-Arabic traditional medicine as practiced in Mughal India and in Muslim culture in South Asia and modern day Central Asia. The term is derived from Arabic Yūnānī "Greek", as the Perso-Arabic system of medicine was in turn based on the teachings of the Greek physicians Hippocrates and Galen.
The Hellenistic origin of Unani medicine is still visible in its being based on the classical four humours: Phlegm (Balgham), Blood (Dam), Yellow bile (Ṣafrā') and Black bile (Saudā'), but it has also been influenced by Indian and Chinese traditional systems.
Unani medicine is substantially based on Ibn Sina's The Canon of Medicine (11th century).
The medical tradition of medieval Islam was introduced to India by the 13th century with the establishment of the Delhi Sultanate and it took its own course of development during the Mughal Empire, influenced by Indian medical teachings of Sushruta and Charaka.Alauddin Khilji (d. 1316) had several eminent physicians (Hakims) at his royal courts. This royal patronage meant development of Unani practice in India, but also of Unani literature with the aid of Indian Ayurvedic physicians.
