The Basics
Kava kava, also known as kava root or simply kava, is used to treat stress-related disorders, depression, anxiety, insomnia, pain, stiffness, and infections affecting the reproductive and urinary organs. It has antiseptic properties.

Kavapyrones, a key chemical component in kava is believed to impact the brain much the same way as certain pharmaceutical drugs. Kavalactone, another active chemical in kava, can numb the mouth, gums, and/or tongue.

Sources
Kava kava is available in the following forms: liquids, extracts, tinctures, tablets, capsules, powdered, or crushed. For maximum benefit, purchase standardized products (70% kavalactone).

While I have had some patients that describe improvement of their symptoms from various dietary supplements, there is little scientific evidence that they work. In small amounts, I do not believe they are harmful, but I am not convinced they are any more effective than adhering to a healthy, well-balanced diet. On the contrary, there is strong scientific evidence showing that patients with a poor overall nutritional status have higher complication rates from surgery.
