In medicine, both ancient and modern, a<unk>  is any of various disorders. The word has ancient Greek roots meaning "bad mixture". The concept of<unk>  was developed by the Greek physician Galen (129–216 AD), who elaborated a model of health and disease as a structure of elements, qualities, humors, organs, and temperaments (based on earlier humorism). Health was understood in this perspective to be a condition of harmony or balance among these basic components, called eucrasia. Disease was interpreted as the disproportion of bodily fluids or four humours: phlegm, blood, yellow bile, and black bile. The imbalance was called<unk> . In modern medicine, the term is still occasionally used in medical context for an unspecified disorder of the blood, such as a plasma cell<unk> .
