Kava is a perennial tropical shrub known botanically as Piper methysticum, a member of the Piperaceae family native to the Pacific Islands. It has heart-shaped leaves and knobby underground parts, and the peeled root and rhizome are the portions traditionally used.
In Pacific Island traditions, kava has a long history as a ceremonial and social beverage prepared from the root. In modern herbal use it is often associated with relaxation-focused preparations, although its traditional cultural role is central to understanding the plant.
Kava is one of the herbs that carries important modern safety discussion, especially regarding concentrated extracts and liver considerations.
