Kava is a shrub, a member of the pepper family, native to the Pacific Islands (Polynesia, Micronesia, Melanesia, Hawaii) where the natives cultivate this plant because of the medicinal virtues of its roots.
Origin of Kava
For thousands of years, natives of the Pacific islands derive a beverage from the roots of the kava plant that improves mood and is used for socialization. Captain James Cook was the first to relate this traditional use in his travelogue about his journey to these islands in 1768-1771. Despite the efforts of Christian missionaries to eradicate the consumption of kava drink, still there are “kava bars” on some of the Pacific islands. These places often host foreign dignitaries by organizing a ceremony during which the ritual consumption of kava promotes harmonious social relations.

Kava root extract formed by grinding the roots and mixing the pulp with water, is drunk to purify urinary tracts, to lose weight and to alleviate the asthma and rheumatism. Kava is known to cure headaches, spasms and to calm syphilis and gonorrhoea. Even today, many islanders believe that Kava is an aphrodisiac that restores physical strength and soothe stomach pains.
