grapefruit seed extract
Refreshing and nutritious, grapefruit possesses very much the same properties as the orange, pomelo, lemon and lime. It is sometimes cut into half, and the seeds are removed from the center. The seeds of this fruit are known to contain high levels of antioxidant properties. grapefruit seed extract also contains benzethonium chloride, a synthetic antimicrobial agent commonly used in cosmetics and only approved for topical use, at relatively high levels of 8%. However, it is reported that grapefruit seed extracts containing benzethonium chloride in concentrations of 7-11% represent a major health risk if larger amounts of a concentrated solution are ingested (that is, taken orally or by the mouth for digestion or absorption).
