Phototoxicity of traditional chinese medicine (TCM)

Abstract

Phototoxicity can cause toxic responses such as edemas and lesions, and is one of the severe adverse effects that largely limit the use of these phototoxic drugs. Some traditional Chinese medicines (TCMs) and their constituents have been reported to be phototoxic. However, to date, their phototoxicity information is still very limited, and lacks systemic investigation. This article presents the phototoxicity potential of various types of TCMs and their active components in an effort to provide valuable information for drug research and discovery to mitigate phototoxicity concerns. Some potential mechanisms of action (MoAs) of phototoxicity are discussed. In addition, in vivo and in vitro phototoxicity assays are summarized this review.
