Kava has been a controversial herbal extract in the dietary supplement industry since 2002. In the last 15 years, Kava extract has been restricted in the Great Britain (UK), Germany, Switzerland, Canada, Australia, France, and many other countries following reports that it was linked to serious toxic liver injury. Then the good news comes! Kava kava extract is back! Kava Ban in Germany is officially repealed in 2014. Kava extract supplements are legal and have never been banned in the United States. Australia’s Therapeutic Goods Administration (TGA) amended its regulations to approve water-soluble kava extracts and dried kava rhizome for use in tea bags for over-the-counter (OTC) therapeutic use in 2005, thus restricting use of alcoholic and/or acetonic kava extracts.

1. Yangonin
2. Dihydrokavain
3. Kavain
4. Dihydromethysticin
5. Methysticin
6. Demethoxyyangonin

HPLC Chromatogram shows that there are six major peaks with retention times of 11.28, 12.28, 15.25, 17.57, 19.57, and 25.75 minutes, corresponding to desmethoxyyangonin, dihydrokavain, yangonin, kavain, dihydromethysticin, and methysticin, respectively.

Yangonin is highest (about 42%) followed by dihydrokawain (35%) and kawain (9%) dihydromethysticin (4%) methysticin (3%) and 5,6-dehydrokawain (2%) The two kawain molecules have larger ranges of probable content, as a consequence of getting interconverted within the Kava plant. 12 other lesser lactones comprise 4% of total kavalactones by weight.

Then a question is asked, what else are inside the extract except the kavalactones?

The kava crisis started in the year of 2001, when health authorities of Swiss and German began to restrict the sale of kava-containing food and medicinal items because of a small variety of cases of adverse reactions reportedly related with the use of kava (Piper Methysticum).
