tonga
Meaning of tonga: Tonga is an alternate name for kava, a South Pacific plant whose root preparation is used traditionally for its calming and sedative effects.
Definition of tonga
Tonga is one of several names used for kava, a plant native to islands of the South Pacific and known scientifically as Piper methysticum. Preparations made from the plant's root have long been used in Pacific Island cultures as a ceremonial and social beverage valued for its calming, mildly sedating effect.
Kava has also been used in some traditions to ease tension, anxiety, and sleeplessness, and it is sold in various parts of the world as an herbal supplement marketed for relaxation. Its effects can be intensified when combined with alcohol or with other substances that also cause drowsiness.
Kava preparations have been linked to cases of serious liver injury, and this risk has led some regulators to issue warnings about its use. The plant is also known by other names, including kava kava, intoxicating pepper, and yangona, and should not be confused with the Pacific island nation of the same name.
