The term Yūnānī means 'Greek',[4][5] referring to the fact that the Perso-Arabic system of medicine was based on the teachings of the Greek physicians Hippocrates and Galen.[6]
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.[7]
