[Research progress of neuroprotective mechanisms of Gastrodia elata and its preparation].

The effects of Gastrodia elata on preventing decrepitude and advancing memory are closely associated with its neuroprotective activity. Previous researches proved that G. elata, its active components and preparations played a neuroprotective role by affecting the excitotoxicity, nitric monoxide (NO) system, neuroglia, biomembrane, oxidative neurotoxicity, apoptosis et al. Recent researches also suggest that reducing energy metabolism impairment, anti-inflammatory and immune modulating function may be new research targets of neuroprotective mechanism of G. elata.
