This is fascinating, I had not heard of LegitScript.
I do know for certain that FDA monitors comments etc. on kava social media.
Also--
For those interested, here is a small portion of the 1998 Wall Street Journal story I referred to.
"Somewhere", in a box, I have the whole story:
Kava Hopes It's Set to Become The Next Big Herbal Blockbuster

Chris Kilham was working in a Brookline, Mass., natural-food store in 1980 when he first tasted an herbal remedy called kava. It came from the root and stem of an obscure South Pacific plant. "A sensuous wave of muscular relaxation washed slowly throughout my entire body," he later wrote, "like India ink spreading on white paper."
Today, thanks to behind-the-scenes promoting by Mr. Kilham and a cadre of other devotees, kava is poised to become the next blockbuster herbal remedy. For the millions who bought ginkgo biloba to sharpen their memory and St. John's wort to treat depression, kava is being pitched as a natural way to heal another big modern woe: anxiety.
