Muhammed Tughlaq established hospitals. A versatile scholar, Muhammed used to sit by the patients and watch the symptoms of extra ordinary diseases. His successor Firoz Tughlaq established a hospital where patients used to get free medical help and also food and drinks. This hospital was open to all. Though Firoz was known for his bigotry, we find no discrimination made between muslims and non-muslims in case of patients in this hospital. Firoz invented an eye-ointment in which, skin of black snake was used. It cured many kinds of eye diseases. This fact supports the Ayurvedic theory of and prescriptions for curing blindness with the ointment prepared with the flesh of cobras. Firoz himself was a good bone-setter.
