Description
Name
Piper methysticum, G. Forst. (Family Piperaceae), commonly known as kava kava, `ava, or kawa. Fijians call it yaqona, and sometimes "grog." In German it is Kava-kava-Wurzelstock.
Source
Kava belongs to the pepper family (Piperaceae) and grows in Polynesia, Melanesia, and Micronesia. Kava kava is made from the dried rhizomes of Piper methysticum G. Forster. There are dozens of different but related strains and they all contain the same psychoactive principles.
History
Pacific Islanders use kava as a depressant drug. The first published account in European literature was written by the Dutch explorers, Jacob LeMaire and William Schouten in 1616, when they visited the Home Islands (now part of the French Wallis and Futuna) and watched a kava ceremony. The Dutchmen were a bit put off by the way the kava was prepared - roots were chewed and the pulpy material expectorated into one bowl that everyone drank from. Schouten wrote, "They presented also their desirable drink to our people, as a thing rare and delicate, but the sight of their brewing had quenched our thirst."
The Dutch reports did not create much of a sensation, but Captain James Cook's account, written in 1770, found a wider audience. A botanist sailing with Cook on his second expedition drew detailed descriptions of the plant and named it Piper methysticum ("intoxicating pepper"). In some areas, especially Tonga, Fiji, and in the islands of Micronesia, kava is still used ritually, although it can be, and is, used as an intoxicant. The first modern studies of kava were done in the early 1900s, when parts of Samoa belonged to Germany. Representatives of the German pharmaceutical industry began to experiment with kava extracts. For a time, kava-based products were used as diuretics, and as a not very successful treatment for gonorrhea. After World War II, Riker Laboratories, an American pharmaceutical maker, tested one of the kava pyrones (dihydromethysticin) in volunteers. They found that large doses (500 mg a day) produced effects much like those produced by any other minor tranquilizer, but that it also caused skin disease (a scaly rash and yellow discoloration) in so many of the participants that the study had to be discontinued.
During the early 1980s, excessive kava consumption became a problem among Australian Aborigines in an area known as the Arnhem Land, in the Northern Territory. There, ritual kava consumption has been replaced by heavy daily usage. Medical surveys done by Australian researchers uncovered a number of undesirable health consequences. A decade later, kava abuse is still a problem for the Aborigines, and the situation does not appear to be improving.
Kava-containing preparations had been widely available in the United States and in Europe. Kava was used as a minor tranquilizer and as a treatment for anxiety. Kava was sold under the brand name Laitanm or Kavasporal in Germany, as Potter's Antigian Tablets in the United Kingdom, and as Viocava in Switzerland.
Traditional Claims
Sedative.
Commission E Recommendations
Kava is used to treat anxiety, muscle pain, restlessness and stress.
Proven Effects
The chemically active components of kava are called pyrones. The two main pyrones are dihydromethysticin and kawain. In addition to being depressants, producing effects very much like those of any benzodiazepine (such as Valium or Librium), these drugs have anticonvulsant activity, analgesic effects, and muscle relaxing properties. In 1990, the Federal Board of Health in Germany approved kava products for treating the symptoms of anxiety. At the molecular level, kava pyrones behave very much like the antiepileptic drug Dilantin. Kava also has an unexplained effect on the smooth muscles that control pupil size, an action that can sometimes lead to trouble focusing. In addition, some of the pyrones can prevent the reuptake of neurotransmitters. Preventing reuptake means that the effects of the neurotransmitters are exaggerated and prolonged. Prozac, for example, is thought to improve the symptoms of depression because it prevents the reuptake of serotonin. Cocaine causes euphoria by preventing the reuptake of another neurotransmitter called dopamine.

Directions
150 mg twice a day containing 30% Kava lactones.
Dosage
Dosage is problematic. Kava for export is usually sold as a dry powder to be mixed with cold water. Total dose will depend on the type of powder, the amount of water added, and how long it is allowed to sit. This makes the dosage extremely unpredictable.
When Riker Laboratories gave volunteers 500 mg per day they became ill. But in another study, no problems were encountered with the 100 mg per day dose.
Commission E recommends a daily dose of 60-120 mg Kava Pyrones.

Cautions
Concerns
Heavy users develop a reversible, scaly skin rash known as kava dermopathy. This disorder was first described by the botanist who sailed with Captain Cook. It is thought to be the result of a kava-related abnormality in cholesterol metabolism. In addition to the distinctive skin rash, Australian researchers studying aboriginal kava abusers have found evidence of weight loss and liver damage (elevated levels of certain enzymes in the blood which are markers for liver disease). Long-term follow-up is not available, so it is not known whether the liver damage is reversible. Results from the same set of Australian studies also suggested that kidney damage might be detected in long-term users, but the evidence was less convincing. Users should know that kava can cause dry mouth, dilated pupils, and trouble focusing (collectively these are known as anticholinergic symptoms). Another consequence of long-term kava use is discoloration of the hair and nails.
Warnings
Kava is not known to interact with any medications, but it is not a good idea to combine depressants. Also, kava should not be used with alcohol. Anyone who takes kava for a long enough period is guaranteed to get the distinctive skin rash, discolored hair and nails, but it will go away if the drug is discontinued. There are recent reports in the literature suggesting that use of kava-based commercial products can cause movement disorders (called choreoathetosis), much like those seen in patients taking medication for schizophrenia (drugs like Haldol). This disorder is self-limiting and quite rare, but should it occur it is imperative you tell your physician which herbal products you are taking.
Drug Testing
Kava pyrones are not known to interfere with, or be detected by, any of the standard screening tests used for workplace drug testing.
