"The great names in Hindu medicine are those of Sushruta in the fifth century before, and Charaka in the second century after Christ. Sushruta, professor of medicine in the University of Benares, wrote down in Sanskrit a system of diagnosis and therapy whose elements had descended to him from his teacher Dhanwantari. His book dealt at length with surgery, obstetrics, diet, bathing, drugs, infant feeding and hygiene, and medical education."
