Kava kava Category: Sedatives

Also called: piper methysticum, yaquona root.

How it’s used

Kava is made from the root of the yaquona plant. In Polynesia it is used as a popular drink or remedy to treat anxiety. It comes in capsules or in its raw form. You can eat it or dissolve in liquid. Kava was withdrawn from legal sale in Ireland in 2002 because it was linked to serious liver problems in other countries.

Long-term effects

If you are pregnant

All drugs can become habit forming but the risk with kava is quite low.


Even though people in the South Pacific use it in high doses, no withdrawal symptoms have been reported.
