Kava Kava Nearly 50% of the adult population in North America, integrate some form of complementary medicine as an essential part of personal health caring. This includes using natural food supplements each highlights a specific value in relieving certain complaints. In a survey carried out by the Canadian College of Naturopathic Medicine, 3.1% of participants were using Kava Kava as a nutritional supplement (Busse and others p. 618). With increasing tendency to go for alternative or complementary food patterns, it is pressing to provide proper information about the supplement foods (Lam and Szmitko, p. 63). The aim of this essay is to provide a brief yet a comprehensive review of Kava Kava as a nutritional supplement applying proper nutrition knowledge. Kava Kava is also famous as Awa, Ava, or Yagona, and scientifically as Piper methysticum. The plant is a strong, tall (2-2.5 meters), erect, barricading, and well branching shrub. The leaves are characteristically heart shaped, green, and smooth on either side. Its flowers are long and lean growing at the points of meeting between the stem and branches. The plant is uniquely uncultivable as it does not produce female flowers, and produces no seeds. Recultivation is through using roots’ rhizomes. It grows all the year-round mainly in south pacific islands including Hawaii and becomes mature after 3-5 years from cultivation. People use its root extract as a supplement food. It is also available as tea, pills, and capsules, typically, the root is chewed or adding the root pulp to cold water and drinking the resulting decoction (Food Standards Australia and New Zealand, Pp. 6-7). Kava is a central part of the culture, beliefs, and society heritage of the people of Polynesia, a group of islands in the South Pacific, and people of Micronesia, Western Pacific self-ruled island country in free association with the US.

Following explorers and anthropologists experienced its relaxing, and soothing effects (Rouse, Pp. 1-2). Kava kava main active ingredients are 15 alkaloids collectively named kava pyrones and lactones. The ratio of active ingredients varies depending on the root’s age and the kava type because each plant breed has a different ratio of active alkaloids. These alkaloids act on the Gamma-Amino Butyric (an amino acid acting as a CNS neurotransmitter) receptors known as GABA receptors in different ways. They act through dopamine anta
