Abstract: According to recent epidemiological reports more and more people, both healthy and ill, use all kinds of Chinese herbal medicine during their lifetime.As the increasing combined usage of Chinese herbal medicine with prescription drugs, it draws lots of attentions on the therapeutic activity due to possible drug-herb interaction. It is known that P-glycoprotein (P-gp)together with cytochrome P450 3A4 (CYP3A4)leads to a highly efficient barrier for many orally absorbed drugs.Meanwhile, more than 50% of the clinical drugs are metabolized by CYP3A4 or transported by P-gp.Hence, more attention should be paid to MDR-and CYP3A4-mediated drug-herbal interactions.This survey discusses the key-factors of drug-herbal interaction as well.

Key words: P-glycoprotein, CYP3A4, prescribed drug, herb, bioavailability
