medical use of marijuana
Marijuana has a long history of medical use. It is one of the oldest living plants and, in ancient times, was used as various forms of medicine through ingestion of the plant. The first recorded use of marijuana as medicine was in China. It was reported in Pen Tsþoo Ching in first or second century A. D. It reported that ma-fe-san(boiled hemp compound) was used as an anesthetic for surgical patients. Ma fen (the fruit of hemp) had many uses such as clearing blood and cooling temperature, relieving fluxes, undoing rheumatism, and discharging pus for patients. China is not the only country to use the drug in early times. It was introduced to southeast Asia around sixteenth century A. D.
