[Historical records and modern studies on agarwood production method and overall agarwood production method].

Agarwood is a precious traditional Chinese medicine with the efficacy of promoting qi circulation and relieving pain, warming middle-jiao, controlling nausea and vomiting, governing inspiration and relieving asthma, therefore it is widely applied in the clinic. Meanwhile, agarwood is also a precious spice. Aquilaria sinensis is the only source of agarwood production in China. Under natural conditions, a healthy A. sinensis tree produces no agarwood. Only if being wounded or infected with fungus can it synthetize and accumulate agarwood. It takes a decade or even several decades to produce agarwood, thus natural agarwood can not meet market demands. The essay summarizes historical records of agarwood production method and modern agarwood production method, in order to provide basis and reference for large-scale production of agarwood.
