Kava is an herbal remedy that's made from the roots of Piper methysticum -- a type of plant found in the islands of the Pacific Ocean. Its name literally means “intoxicating pepper.” People who live on Pacific islands like Fiji and Tonga have used it for hundreds of years in social gatherings and traditional medicine.
Kava contains substances called kavapyrones. They act much like alcohol on your brain, making you feel calm, relaxed, and happy. The plant is also thought to relieve anxiety, pain, prevent seizures and relax muscles.
