Generally, alopecia is interpreted by Chinese doctors as the result of a deficiency syndrome, specifically involving blood deficiency, with generation of internal wind or invasion of external wind that affects the head; the situation is sometimes complicated by blood stasis and/or blood heat. The belief that there is an influence of wind in the etiology of the hair loss is reflected in the Chinese name for the disease, which is youfeng, literally oil-wind. The reference to oil, which can also mean glossy, is an expression characterizing the smooth, shiny scalp appearance where the hair has been lost. The Chinese name has led to some humorous translations; in the package insert for Alopecia Areata Pills, the primary indication is for "grease hair dropping."
