Unani or Yunani medicine (Urdu: tibb yūnānī) is Perso-Arabic traditional medicine as practiced in Muslim culture in South Asia and modern day Central Asia. Unani medicine is pseudoscientific. The Indian Medical Association describes Unani practitioners who claim to practice medicine as quacks. The term Yūnānī means "Greek", as the Perso-Arabic system of medicine was 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 (), blood (dam), yellow bile (ṣafrā) and black bile (saudā'''), but it has also been influenced by Indian and Chinese traditional systems. History Arab and Persian elaborations upon the Greek system of medicine by figures like Ibn Sina and al-Razi influenced the early development of Unani. Unani medicine interacted with Indian Buddhist medicine at the time of Alexander's invasion of India. There was a great exchange of knowledge at that time which is visible from the similarity of the basic conceptual frames of the two systems. The medical tradition of medieval Islam was introduced to India by the 12th century with the establishment of the Delhi Sultanate and it took its own course of development during the Mughal Empire,Kapoor, p. 7264 influenced by Indian medical teachings of Sushruta and Charaka."Interaction with China and Central Asia in the Field of Unani Medicine" by Hakim Syed Zillur Rahman, History of Science, Philosophy and Culture in Indian Civilization, Vol. III Part 2 (India’s Interaction with China, Central and West Asia), Ed.

This royal patronage led to the development of Unani in India, and also the creation of Unani literature.Bala, p. 45 Education and recognition There are several Indian universities devoted to Unani medicine, in addition to universities that teach traditional Indian medical practices in general.
