Toxicological trivia from November 04, 2016: Kava or kava-kava (Piper methysticum: Latin "pepper" + Latinized Greek "intoxicating") is a crop of the western Pacific. The roots of the plant are used to produce a drink with sedative, anesthetic, euphoriant, and entheogenic properties. Kava is consumed throughout the Pacific Ocean cultures of Polynesia, including Hawaii, Vanuatu, Melanesia and some parts of Micronesia. (See canoe plants.) Kava is sedating and is primarily consumed to relax without disrupting mental clarity. Its active ingredients are called kavalactones.
