The protective effects of Kava (Piper Methysticum) constituents in cancers: A systematic review

Abstract

BACKGROUND: Kava is a beverage made from the ground roots of the plant Piper Methysticum and has long-held a significant place within Pacific island communities. Active compounds were extracted from kava, and secondary metabolites include kavalactones, chalcones, cinnamic acid derivatives and flavanones. It is thought that components of kava may exert an antiproliferative effect through cell cycle arrest and promotion of apoptosis. METHODS: We conducted a systematic review to summarize available evidence of the anticancer effects of kava components and investigate their potential use for oral squamous cell carcinoma (OSCC) treatment. Eligible studies were identified through a comprehensive s..
