Can’t sleep? Need to relax? Stressed out? And you haven’t tried Kava yet? Since its introduction, users have raved over this 100% organic sedative herb, and its ability to encourage a natural state of relaxation. It gets its power from high concentrations of kavalactones present in the plant’s thick roots. Kavalactones have been shown in many studies to promote a calming effect on the body’s limbic system – a region of the brain that regulates emotion. And while it’s always wise to consult a physician before use, Kava appears to be safe when taken as recommended. NOW Kava contains 100% root extract.
