Kava, also known as piper methysticum, kava kava, and ‘awa, is a small shrub native to the islands in the South Pacific. The root and stems are made into a non-alcoholic, psychoactive beverage that has been used socially and ceremonially for hundreds of years in Hawaii, Fiji, and Tonga.
Kava's calming effect may relieve anxiety, restlessness, sleeplessness, and stress-related symptoms such as muscle tension or spasm. Kava may also relieve pain.
When taken for anxiety or stress, kava does not interfere with mental sharpness. When taken for sleep problems, kava promotes deep sleep without affecting restful REM sleep.
Kava may be used instead of prescription antianxiety drugs, such as benzodiazepines and tricyclic antidepressants. Kava should never be taken with these prescription drugs. Avoid using alcohol when taking kava.
