Ibn Sina was a brilliant physician and thinker. Afghans believe that he was born in 980 AD in Balkh (Northern Afghanistan). Others place his birthplace in Bukhara. He is known by many as the “Prince of Physicians”. His works, the Canon of Medicine and the Book of Healing are considered his greatest achievements. The Canon contained all sorts of information about diet, discussions on various diseases such as rabies, breast cancer, meningitis, etc. The work also contained a description of 760 medicinal plants and various drugs that can be obtained from them. The Canon was the standard medical reference in Europe for centuries. Ibn Sina died in 1037.
