Abstract
A method of making an extract from kava-kava root includes drying the kava-kava root, and grinding the dried root to a powder. Compounds are extracted by contacting the ground root with CO at an extraction pressure of at least about 500 bar, and at a temperature of less than about 65° C. The dissolved kava-kava compounds are separated from the CO into at least a first fraction by collecting the carbon dioxide after extracting and decreasing the pressure to a predetermined first separation pressure lower than the extraction pressure, at a temperature sufficient to prevent the carbon dioxide from solidifying. A composition including a kava-kava extract comprises greater than about 70% kavalactone, greater than about 0.3% flavokawin, and preferably comprises about 30% flavokawin. The composition comprises substantially no solvent residue and includes a pharmaceutically acceptable carrier. The composition is taken orally for nutritinal supplementation in a substantially soft gel capsule.
