Charaka also mentions two types of diabetics: one,
very emaciated and weak, and the other stout and strong.
Ancient Indian doctor, Charaka had rightly said“Not for self, not for the fulfilment of any earthly desire of gain,
but solely for the good of suffering humanity will I practice my art and so excel all.
The premonitory symptoms in diabetes, according to Charaka, are matting of hair(
the well- to- do class of men in ancient times grew long hair), sweet taste in the mouth and numbness and burning of the palms and the soles.
The researches of Aryabhatta, Varahamirnra and Brahmagupta in mathematics and astronomy, of Charaka and Susruta in medicine,
guided scientists in other lands for centuries and exercised a direct influence on scientific thought of Arab and other Islamic countries and, indirectly, on Europe.
