Kava Kava Root
Latin name: Piper methysticum
A Remedy For
In the past, Kava Kava has been taken for a host of ailments on which it has no appreciable effect, including asthma, arthritis, indigestion, cystitis, syphilis, and gonorrhea. For tension and sleeplessness, however, it is now considered a proven remedy.
What It Is; Why It Works
One of the “new” herbs that have recently gained considerable media attention, Kava Kava has actually been around for centuries in the South Seas, where it’s used as a ceremonial beverage. The plant’s fleshy underground stem is mildly intoxicating when chewed. Prepared as a nonalcoholic drink, it is said to foster a sense of contentment and well-being, while sharpening the mind, memory, and senses.
Research shows that the active ingredients in Kava Kava (kava pyrones) do in fact have a calming, sedative effect. They also appear to relax the muscles, relieve spasms, and prevent convulsions. At least two scientific studies have confirmed the herb’s ability to significantly reduce symptoms of anxiety. In a third study, researchers rated it as effective as prescription tranquilizers.
Avoid If…
Do not use Kava Kava if you are pregnant or nursing. Also avoid it if you have a depressive disorder; it can deepen a depressed mood.
Special Cautions
When first taking Kava Kava, you may notice a slightly tired feeling in the mornings.
In rare cases, Kava Kava can cause an allergic reaction, a slight yellowing of the skin, gastrointestinal complaints, impaired or abnormal movement, loss of balance, pupil dilation, and difficulty focusing. Because of the possibility of visual disturbances, drive with caution while using this herb.
High doses of the herb have been known to trigger hepatitis. Heavy long-term use can also cause an unusual scaly rash, and may lead to unwanted weight loss. Do not take this herb for more than 3 months without consulting a physician.
Possible Drug Interactions Do not take Kava Kava when using other substances that act on the brain, such as alcohol, barbiturates, or other mood-altering drugs. It may increase their effect. Be especially wary of taking it with the tranquilizer Xanax; the combination has caused coma.
Kava Kava also has an antagonistic effect on dopamine. If you are taking a levodopa-based medication for Parkinson’s disease, avoid this herb.
Special Information If You Are Pregnant or Breastfeeding
Remember, Kava Kava should be avoided during pregnancy and nursing.
How To Prepare
Commercial extracts are the predominant form of Kava Kava. The crushed root can also be used.
Typical Dosage
Daily doses delivering between 50 and 240 milligrams of the active ingredients are the customary recommendation. Commercial capsules containing between 150 and 300 milligrams of root extract may be taken twice a day. Because the potency of commercial preparations may vary, follow the manufacturer’s directions whenever available.
Overdosage
An overdose is usually signaled by a lack of coordination, followed by tiredness and a tendency to sleep. If you suspect an overdose, seek medical attention immediately.
