title: Categorization of Cathartic (Purgative) Medicines Mentioned in TPM Resources According to Their Specific Function.
abstract: BACKGROUND
  According to traditional Persian medicine (TPM) resources, the human digestive system includes four steps. In the first step, gastric digestion, the ingested food pours into the stomach and changes into the leachate called chylous due to the heat produced in the stomach. In the second step, hepatic digestion, the chylous enters in the liver through mesenteric vessels and transforms into the quadruple humors, sanguine, phlegm, bile and black bile due to the liver heat. In the case of humor predominance, using moshel or cathartic medicines is considered as a strategic medical plan. In this study, we introduce cathartic (purgative) medicines mentioned in TPM resources according to their specific function.
