The Soothing Power of Kava: A Root for Anxiety Disorder Sufferers

If you are one of the more than 19 million adults in this country who suffer from an anxiety disorder, you may be familiar with the commonly prescribed benzodiazepine drugs. While these are effective and fast acting, you may also be familiar with their undesired side effects, primarily, their tendency to cause severe drowsiness and to lead to dependency. Fortunately, researchers are examining the herb kava, or kava kava as it is popularly known, as an alternative treatment.

The Polynesians of the South Pacific have used kava for more than 3,000 years. They discovered that a concoction made from the root of the kava plant could help calm a person without reducing mental sharpness. The results of several clinical studies have now backed up the Polynesians' practices. Kava has been shown to significantly reduce anxiety as effectively as some common benzodiazepine-type drugs, but without the side effects. In fact, any side effects of using kava seem slight, although they have not been thoroughly researched yet (so far experts have determined that chronic abuse of kava can lead to liver damage and yellowing of the skin).

So consider taking kava as an alternative treatment if you suffer from an anxiety disorder. If you are currently taking a prescription, talk to your doctor about kava as an alternative. A standardized capsule of kava containing 60 mg to 120 mg of kavalactones is the recommended dosage. It may take a month before you notice a change in your condition. If you do not see results after three months, seek further medical advice.

Note: Low doses of kava can help you stay aware and active but not tense; at higher dosages, however, you may become sleepy. Since kava is known to depress the nervous system, until it is better researched, do not take it with alcohol or other depressants.

Glossary


Anxiety disorder: Acute feelings of fear, uneasiness, or distress for no apparent reason. Panic attacks or various phobias, such as a fear of heights, may characterize an anxiety disorder.

Benzodiazepine: Family of drugs commonly used to treat anxiety.

Kavalactones: The active ingredient in kava. The amount of kavalactones per kava capsule may vary from one manufacturer to another, so look at the label to make sure the percent of kavalactones in one dose is equal to 60 to 120 mg kavalactones. For example, a 100 mg capsule of kava containing 70% kavalactones has 70 mg of kavalactones.
