Yellow Bile

Yellow bile is one of the four bodily fluids, or "humors," in ancient Greek medicine, which also included blood, phlegm, and black bile. According to this historical belief, an imbalance of these humors was thought to influence a person's health and temperament. Yellow bile was associated with the element of fire and was believed to contribute to qualities like anger and irritability. While this concept is outdated and not supported by modern medicine, it played a significant role in the development of early medical theories and the understanding of human health in ancient cultures.
