kavalactones

The most common natural products containing a 2-pyrone are the bufanolides and kavalactones.

Yangonin is one of the six major kavalactones found in the kava plant.

Lecithin is often added to aid in the process of emulsifying the kavalactones with water.

The active ingredients are chemicals called kavalactones, which have a mildly depressing effect on the nervous system.

They are thought to result from direct interactions of kavalactones with voltage-gated ion channels.

At least 18 different kavalactones have been identified to date, with methysticin being the first identified.

Inhibition of human cytochrome P450 activities by kava extract and kavalactones.

The significant secondary metabolites of Kava are kavalactones and flavokawains.

Kavalactones are a class of lactone compounds found in the kava shrub.

Its active ingredients are called kavalactones.

Traditionally, plants are harvested around four years of age, as older plants have higher concentrations of kavalactones.

The authors discovered the glutathione in traditional preparations interacts with the kavalactones and prevents cell death.

Kava's active principal ingredients are the kavalactones, of which at least 15 have been identified and are all considered psychoactive.

Kava lateral roots have the highest content of kavalactones in the kava plant.

By comparison the typical bowl of traditionally prepared kava beverage has around 250 mg of kavalactones.

The kava is first chewed in the back of the mouth for five to 10 minutes while swallowing the saliva and kavalactones released from the process.

They claim that in all standardized extracts that contributed to liver damage, there were only the kavalactones without any glutathione.

As more pressure is applied to the wet powdered pulp while wringing it out, more kavalactones will be released from it.

The Australian Therapeutic Goods Administration has recommended no more than 250 mg of kavalactones be taken in a 24 hour period.

The mechanism behind the psychotropic, sedative and anxiolytic actions of kavain and related kavalactones is still debated.

Effects of kavalactones include mild sedation, a slight numbing of the gums and mouth, and vivid dreams.

Research currently suggests kavalactones potentiate GABA activity, but do not alter levels of dopamine and serotonin in the CNS.

How this effect is mediated and to what extent this mechanism is involved in the anxiolytic and analgesic effects of kavalactones on the central nervous system is unknown.

The majority of evidence shows that certain kava extracts (extracts standardized to 70% kavalactones) can lower anxiety and might work as well as prescription anti-anxiety medications called low-dose benzodiazepines.

The numbing of the mouth is caused by the two kavalactones kavain and dihydrokavain, which cause the contraction of the blood vessels in these areas, acting as a local topical anesthetic.
