Abstract: The Blumea balsamifera powder is a crude product of borneol.The plantation area of Blumea balsamifera is far from factory,so it costs too much traffic expenses.On the other hand,the traditional processing leads to low rate of abstraction.In order to decrease the production costs of Blumea balsamifera powder and effectively improve the rate of abstraction,many experiments have been carried out on the abstraction technotogy of Blumea balsamifera since 2002.The results show that the output and rate of abstraction Blumea balsamifera powder was improved when the plant was picked up from October to December and extracted with condensation distillation for 1h.

Key words: Blumea balsamifera, Blumea balsamifera powder, abstraction
