[Systematic evaluation for safety of traditional Chinese medicine Areca catechu and its preparations].

ABSTRACT

The authors systemically evaluated and analyzed the safety of Areca catechu from domestic and foreign literatures about the herbal origin, toxicity recorded in ancient/current documents, safety case reports of clinical A. catechu, experimental studies on toxicity in recent years, and differences of safety risk between edible and medicinal A. catechu. Subsequently, they proposed a preliminary summary about the clinical characteristics and potential risk factors of safety related cases of A. catechu and its preparations. According to the authors, although clinical adverse events of A. catechu were fewer and controllable, clinicians shall stillstrictly standardize its application, and rationally combine it with other herbs, while strengthening fundamental and clinical studies related to safety, so as to give better guidance to safety application of A. catechu in clinic.
