Frequently Asked Questions

What is Unani medicine based on?▾

Overwhelmingly on one book. Avicenna's Canon of Medicine, written in the eleventh century, is the source behind almost every Unani card in our articles, and it works by temperament: each remedy is placed on a hot–cold and dry–moist scale measured in degrees, so cinnamon is warm and dry in the second to third degree and ginger hot in the third and dry in the second. The Canon also lists sleep and waking among the six essentials of health and treats correctly dosed exercise as something that can make medicine unnecessary. It explains, rather than only prescribing.

Does Unani medicine work?▾

Of thirty-one claims we checked, two were confirmed, fifteen had partial support, four were refuted, and ten had never been tested. What stands out is not the ratio but where the confirmations land: Avicenna is the one classical source in our articles that links bathing and sleep favourably and explains why excessive sleep leaves the body's exterior cold — explanations specific enough to be tested at all. A tradition that argues mechanism gives research something to check, and that shows up in the numbers.
