Avicenna

Avicenna was a Persian traveler who studied philosophy and medicine among other subjects. He lived circa 980 - 1037 AD. One of his most significant works was writing the The Canon of Medicine, which he completed in 1025. It unified all current medical knowledge, and became a standard medical text. It was still used in European universities over 600 years later. Among its many topics, Avicenna wrote about a plant bunn, and hot and dry beverage buncham, which came from Yemen.

This excerpt is the first written account of the coffee beverage in history that still survives to this day. Coffee again appeared in a book covering medicine, further proving that coffee was originally used as a medical beverage.
