Iranian traditional medicine

Iranian traditional medicine (ITM) (Persian: طب سنتی‌ ایرانی, romanized: tebbe sonnati-e irāni), also known as Persian traditional medicine, is one of the most ancient forms of traditional medicine.

ITM is grounded in the concept of four humors: phlegm (Balgham), blood (Dam), yellow bile (Ṣafrā') and black bile (Saudā'). The four humors concept is based on the teachings of Rhazes and Avicenna into an elaborate medical system.

Some scholars believe that efforts for revitalizing ITM in recent years have shaped two main attitudes: evidence-based medicine, and quackery byt there is also a pseudoscientific stream in the field.
