bilis
n. a culture-bound syndrome found among Latino groups, who attribute it to extremely strong anger or rage. Symptoms include abrupt nervous tension, headache, screaming, stomach disturbances, vomiting, loss of weight, tremors, chronic tiredness, and—in extreme cases—loss of consciousness or death. The extreme anger is said to disturb the center of balance of hot and cold in the body, which upsets the material and spiritual aspects of the person. Also called colera; muina.
