"Leeches are useful for nearly all ailments for which we use cups [cupping], especially for lesions of the skin, such as tinea, pustules, infections, and things that accompany corrupt humors, such as itching, scabies, dandruff, impetigo, morphea, albarras, delirium, mania, depression, and for all "unripe" aposthems."  -Henri de Mondeville (1260-1320), medieval French surgeon to Philip the Fair, in La Chirurgie (1306), as translated by Leonard Rosenman, MD
