Editing Humorism (section)

== Humor production ==
Humors were believed to be produced via digestion as the final products of hepatic digestion. [[Digestion]] is a continuous process taking place in every animal, and it can be divided into four sequential stages.<ref>{{cite journal |title=Relation between Body Humors and Hypercholesterolemia: An Iranian Traditional Medicine Perspective Based on the Teaching of Avicenna |journal=Iranian Red Crescent Medical Journal |volume=14 |issue=3 |pages=133–38 |last=Emtiazy |first=M |pmc= 3372029 |year=2012 |pmid=22737569}}</ref> The [[gastric]] digestion stage, the [[Liver|hepatic]] digestion stage, the vascular digestion stage, and the [[tissue digestion]] stage. Each stage digests food until it becomes suitable for use by the body. In gastric digestion, food is made into chylous, which is suitable for the [[liver]] to absorb and carry on digestion. Chylous is changed into chymous in the hepatic digestion stage. Chymous is composed of the four humors: blood, phlegm, yellow bile, and black bile. These four humors then circulate in the [[blood vessel]]s. In the last stage of digestion, tissue digestion, food becomes similar to the organ tissue for which it is destined.

If anything goes wrong leading up to the production of humors, there will be an imbalance leading to disease. Proper organ functioning is necessary in the production of good humor. The [[stomach]] and liver also have to function normally for proper digestion. If there are any abnormalities in gastric digestion, the liver, blood vessels, and tissues cannot be provided with the raw chylous, which can cause abnormal humor and blood composition. A healthy functioning liver is not capable of converting abnormal chylous into normal chylous and normal humors.

Humors are the end product of gastric digestion, but they are not the end product of the digestion cycle, so an abnormal humor produced by hepatic digestion will affect other digestive organs.
