The Sushruta Samhita is best known for its approach and discussions of surgery. It was one of the first in human history to suggest that a student of surgery should learn about human body and its organs by dissecting a dead body. A student should practice, states the text, on objects resembling the diseased or body part. Incision studies, for example, are recommended on "Pushpaphala" (squash, "Cucurbita maxima"), "Alavu" (bottle gourd, "Lagenaria vulgaris"), "Trapusha" (cucumber, "Cucumis pubescens"), leather bags filled with fluids and bladders of dead animals.
