Botanically known as Piper methysticum, kava is a plant native to the South Pacific. Belonging to the pepper family Piperaceae, the plant has been an integral part of religious, political, and cultural life throughout the Pacific region. The plant is often related to black pepper and possesses heart shaped leaves and flowers. Its brown colored roots, called Waka, possess high medicinal value and are used to prepare a popular narcotic drink called kava kava. The drink is prepared by drying the roots under the sun, grounding them into powder, and then mixing the powder with water. Kava kava is a popular social drink in South Pacific and so, apart from its medicinal uses, the drink also plays a significant role in different rituals and ceremonies.
