Kava is a beverage or extract made from the Piper methysticum plant. In the South Pacific, it's a popular drink that is used in ceremonies for relaxation.
The name "kava" comes from the Polynesian word "awa," which means bitter. Kava affects the brain and other parts of the central nervous system. Chemicals called kavalactones that are found in kava are believed to be responsible for its effects.
