Topic: Avicenna
Avicenna is the greatest philosopher and a physician in the East. He was born in 980 in the province of Bukhara in a family connected with public service.
At the age of 10 Avicenna was well acquainted with Koran and Arabic classics. During the next 6 years he acquired a knowledge of philosophy, mathematics, astronomy and medicine.
At 17 his medical knowledge enabled him to cure the Samani ruler Nuh ibn Mansur from dangerous illness. His chief reward was an access to the royal library.
With the ending of the Samanid in 1004 Avicenna spent a short time in the service of the ruler of Kharazm or Khiva. When the ruler of Isfahan captured Hamadan in 1024 Avicenna passed his service as a physician and general literary and scientific adviser.
While marching with the army in a campaign against Hamadan he was seized with severe colic and died in June 1037, at the age of 58.
About 100 treatises are ascribed to Avicenna and the most famous of these was his “Canon of Medicine”. This book was based on the Greek medical works and was long used as a text-book.
“The Canon of Medicine” includes five books. The first and second books describe physiology, pathology and hygiene. The third and fourth books deal with the methods of treating diseases. The fifth book describes the composition and preparation of remedies and includes Avicenna’s personal observations.
Ibn Sina made a great contribution to pharmacology.
“The Canon of Medicine’ describes about 2000 medicines. Of the 2000 150 are included into our Pharmacopoeia.
