[Research progress of Gastrodiae Rhizoma machining processing, composition analysis and in vivo metabolism].

Steaming method is a traditional processing method for Gastrodiae Rhizoma(GR). The current studies on the steaming method's mechanism of GR are mainly focused on facilitating softening slice, destroying the β-glycosidic bond enzymes to reduce the decomposition of gastrodia glycosides (killing enzyme and protecting glycosides). The researches on the processing mechanism are still incomplete, while revealing and analyzing the active components in the body's metabolic process are important channels and new models to clarify the mechanism of traditional medicine processing.
