kava-is a root found on South Pacific islands. Islanders have used kava as medicine and in ceremonies for centuries.
Kava has a calming effect, producing brain wave changes similar to changes that occur with calming medicines such as diazepam (Valium, for example). Kava also can prevent convulsions and relax muscles. Although kava is not addictive, its effect may decrease with use.
Traditionally prepared as a tea, kava root is also available as a dietary supplement in powder and tincture (extract in alcohol) forms.
What is kava used for?
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 sleepwithout 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.
Before you use kava, consider that it:
Should not be combined with alcohol or psychotropic medicines. Psychotropic medicines are used to treat psychiatric disorders or illnesses and include antidepressants and mood stabilizers. Alcohol exaggerates kava’s sedating effect.
Can affect how fast you react, making it unsafe to drive or use heavy machinery.
May gradually be less powerful as you use it.
Eventually may cause temporary yellowing of skin, hair, and nails.
