Kava is a traditional South Pacific root used for calm, social ease, and tension relief. It can feel noticeably relaxing without “knocking you out,” but it’s not for everyone—kava has important liver and sedation cautions, and it should not be mixed with alcohol. Best used short-term or occasionally, not as an everyday forever-herb.
