Yellow bile was associated with a choleric nature (ambitious, decisive, aggressive, and short-tempered). [30] It was thought to be fluid found within the gallbladder, or in excretions such as vomit and feces. [26] The associated qualities for yellow bile are hot and dry with the natural association of summer and fire.
Bile (from Latin bilis), or gall, is a yellow-green/misty green fluid produced by the liver of most vertebrates that aids the digestion of lipids in the small intestine. In humans, bile is primarily composed of water, is produced continuously by the liver, and is stored and concentrated in the gallbladder.
Likewise for being too calm and reserved or "phlegmatic" from too much phlegm; excessively sad or "melancholic" from too much black bile; and too angry or "choleric" from excess yellow bile. [10] The properties of these humours also corresponded to the four seasons. Thus blood, which was considered hot and wet, corresponded to spring.

The second was that humoral balance was the basis of illness or health, the four humours being blood, phlegm, black bile, and yellow bile, relating to the four Greek classical elements of air, water, earth, and fire respectively. Galen believed that blood was the dominant humour and the one in most need of control.
Disease was interpreted as the disproportion of bodily fluids or four humours: phlegm, blood, yellow bile, and black bile. The imbalance was called dyscrasia . In modern medicine, the term is still occasionally used in medical context for an unspecified disorder of the blood, such as a plasma cell dyscrasia .
Yellow bile is not as abundant as phlegm and blood in the body. It is the lightest of all humors. It resembles cooking foam. Yellow bile acts as a diluent and facilitates the transfer of blood and nutrients from capillaries to the remote body organs. [44] It is also in charge of the metabolization of fats and lipids, and eases digestion.
Bilin (also called bilichrome) was named as a bile pigment of mammals, but can also be found in lower vertebrates, invertebrates, as well as red algae, green plants and cyanobacteria. Bilins can range in color from red, orange, yellow or brown to blue or green. [1] In chemical terms, bilins are linear arrangements of four pyrrole rings ...
