根和叶中含双稠吡咯啶生物碱克氏千里光碱，对肝、肺有明显毒性，能致肝癌。据实验研究，刚出生之大鼠较喂乳之幼鼠敏感，较成年大鼠更敏感；因此双稠吡咯啶类物质并非在肝内微粒体（刚出生鼠肝内缺乏代谢酶）变为毒性代谢物，而可能是在体内变为相应的环氧化物（epoxide）而起毒性作用的。相关论述
The roots and leaves contain the bisbenzylisoquinoline alkaloid chelerythrine, which is highly toxic to the liver and lungs and can cause liver cancer. According to experimental studies, newborn rats are more sensitive to chelerythrine than suckling rats, and more sensitive than adult rats. Therefore, it is suggested that bisbenzylisoquinoline alkaloids are not converted into toxic metabolites in the liver (due to the lack of metabolic enzymes in the liver of newborn rats), but may be transformed into corresponding epoxides in the body, which then exert toxic effects. This is a brief summary of the related discussion.
