The present invention relates to a pharmaceutical composition for preventing or treating menopausal symptoms, the composition containing Toxicodendron vernicifluum extract, or a flavonoid compound derived therefrom or a pharmaceutically acceptable salt thereof, as an active ingredient. The Toxicodendron vernicifluum extract or flavonoid compound derived therefrom of the present invention exhibits activity which is more selective for oestrogen receptor beta (ER-β) than for oestrogen receptor alpha (ER-α) and thus, being a phytoestrogen with fewer side effects, can be used to advantage in preventing and treating menopausal symptoms. |
