Early medical practices emerged early on in the Indian subcontinent with the practice of Ayurvedic medicine, one of the earliest texts for which survive being the Sushruta Samhita. Some early Buddhist communities established monastic communities with monasteries, and many of these monasteries were centers of learning for medicine. While sick monks within the monastic communities were usually treated in their own cells, some monasteries reserved a room where sick monks could be taken care of.Mossensohn Hershkovitz, "Early Muslim Medicine and the Indian Context: A Reinterpretation" Medieval Encounters 2013 pg. 291 While some of these rooms in Buddhist monasteries may have been open to the public, the majority were closed off to the public and were reserved for treating other monks within the monastery.C.
