kava kava: a drug prepared from the roots of the shrub Piper methysticum. Chewing the root releases active alkaloids similar to nutmeg and sweet flag. A small or moderate dose of one ounce of finely ground kava to ten ounces of water, blended with coconut oil, gives two to four people a mild but definite euphoria. Stimulation is felt at the beginning, and a pleasant sedation without loss of mental powers occurs afterward. The high lasts about two or three hours, often ending in sleep. With larger doses kava can be hallucinogenic and a powerful sedative. As an aphrodisiac or sexual enhancer, kava kava makes some people glow with psychic and genital euphoria.
