Kava is a relatively good looking ornamental plant, but its fame largely comes from the properties of its roots. Specifically, kava roots are used in many Pacific cultures to produce a drink that has both anesthetic and sedative properties. As such, it acts as a relaxant and may play a role in helping to ease anxiety. At high doses, the plant roots are associated with psychedelic effects, although there is also the potential for health risks at higher doses of the roots.
