Like Ayurveda, Unani medicine also relies heavily on examination of the pulse for diagnostic purposes.

It is the imbalance amongst these four humours that causes disease. Students will get a good glimpse of how Unani doctors interact with their patients and diagnose with the help of pulse examination in these video clips.
