4 humors: black bile, yellow bile, blood, and phlegm
it was applied on people having mental problems..it was said that their mental illness was caused by a disproportion of these 4 moods
It was a very primitive theory. Based on the 4 temperaments or moods which humans showed.....i cant remember what they actually represent...the 4 humors are blood, black bile, yellow bile, and phlegm. I dont think it has any clinical application. Its about the greek physicians n how they related human psychology to human physiology
