What is Kava Root Extract?

Kava root extract, also often called kava kava, is a member of the nightshade family of plants and native to the South Pacific islands.Pacific Islanders have used it for hundreds of years as a ceremonial drink to promote a state of relaxation. More recently, kava has received widespread attention for its relaxing and stress-reducing properties.

Kava root extract come from the rhizomes of a perennial shrub in the South Pacific Islands. The term kava comes from both the kava plant and the kava extracts and is typically consumed as either a capsule or table containing either ethanolic or acetonic extracts. The active ingredients in kava are kavapyrones, also known as kavalactones, which have psychoactive properties.

Kava Root Extract Benefits:

1) Sleep Disorders

Kava root extract reduced stress and improved sleep quality in 24 patients suffering from stress-induced insomnia. 61 patients suffering from sleep disturbances associated with anxiety, tension, and restlessness were also effectively treated with kava extract.

Kava’s potentially sedative effects are due to the blocking of sodium and calcium ion channels, increased neurotransmitter binding to GABA-A receptors, inhibition of monoamine oxidase B, and an increase of the neurotransmitters noradrenaline and dopamine.

Although promising, the evidence to support the use of kava in sleep disorders is insufficient. More clinical trials on larger populations are needed to confirm these preliminary results.

2) Depression

In a clinical trial on 60 people with generalized anxiety disorder, oral kava extract (250 mg kavalactones per day) reduced both anxiety and depressive symptoms. Its combination with Saint John’s wort improved depression (but not anxiety or quality of life) in a small trial on 28 people with major depressive disorder.

Bulk kava extract induced a pleasant mental state while reducing fatigue and anxiety in human and animal studies. Kavalactones in kava increased dopamine, serotonin, GABA (only slightly), and decreased glutamate in cell models. Again, the results are promising but only two small clinical trials have been conducted. Further clinical research is required to confirm the potential benefits of kava in people with depression.

3) Menopausal Symptoms

Perimenopause and menopause symptoms include hot flashes, night sweats, insomnia, and increased anxiety and irritability. Kava root extract improved anxiety, depression, irritability, and insomnia in 3 clinical trials on 120 perimenopausal and menopausal women. It activated GABA-A receptors, inhibited monoamine oxidase-B, and increased dopamine levels in the brain.

All in all, there is insufficient evidence to claim that kava helps with mood symptoms of menopause and perimenopause. Larger, more robust clinical trials are needed to validate these findings.

4) Brain Function

A single dose of kava extract (300 mg) improved accuracy and performance in attention, visual processing, and working memory tasks in a small trial on 20 people. In another trial on 12 people, kava kava root extract (200 mg, 3x/day) slightly improved performance in a word recognition task.

Kava pyrones are active in parts of the brain (amygdala, caudate nucleus, and hippocampus) that deal with emotions and brain processes. However, chronic usage and higher doses of kava can result in impaired motor function. Because only two, very small clinical trials have been conducted, there is insufficient evidence to support the use of kava as a cognitive enhancer. Further clinical research is needed.

5) Treatment of Drug Addiction

Bulk kava extract reduced the cravings for addictive drugs in drug-dependent patients in a pilot study. The anti-craving effects of kava are due to dopamine-producing neurons in the reward system of the brain (nucleus accumbens). The kava pyrone desmethoxyyangonin may increase dopamine. A single pilot study (which we couldn’t access for a critical analysis) is clearly insufficient to back the potential benefits of kava in treating drug addiction. More clinical research is required.

6.Animal and Cell Research (Lack of Evidence)

No clinical evidence supports the use of kava for any of the conditions listed in this section. Below is a summary of the existing animal and cell-based research, which should guide further investigational efforts. However, the studies should not be interpreted as supportive of any health benefit.
