Kava has been used as a ceremonial drink in the South Pacific for centuries and is still consumed for various purposes such as medicine, recreation, and spiritual practices. It is a tall shrub plant with long, slender flowers and large, green, heart-shaped leaves. The roots are in bundles of hairy branches and contain the active ingredients, kavalactones, which have relaxing qualities to the body when consumed (Ehrlich, 2011; Foster, 2006).
