Grapefruit Seed Extract is a powerful disinfectant. It can be used to disinfect wounds, sterilize fruit and vegetables, purify drinking water, sanitize dishes, countertops and cutting boards and inhibit bacteria growth in pools and spas. The active ingredient of grapefruit seed extract is synthesized from the seed and pulp of certified organically grown grapefruit. The process converts the grapefruit bioflavonoids (polyphenolics) into an extremely potent compound that kills Strep, Staph, Salmonella, E. Coli, Candida, Herpes, Influenza, parasites, and fungi.
Research indicates that GSE appears to disrupt the cytoplasm membrane in such a way that the organism is unable to uptake necessary amino acids. While researchers do not yet fully know how GSE works, they do know that it is effective against an overwhelming number of pathogens.
In numerous tests it has shown to have no side effects and is non-toxic to humans and animals. It also environmentally friendly and biodegrades.
It is especially useful for sterilizing baby toys, bottles and clothes because it is non-toxic and harmless to babies. Only the undiluted extract will irritate eyes and skin.

Stephen Harrod Buhner, author of Herbal Antibiotics says “The exact manufacturing process [of Grapefruit Seed Extract] is a closely kept secret, and there some (disputed) evidence that the commercial process involves more than a simple extraction procedure. It is unknown whether simple home extraction processes will produce the same efficacy as the commercial extract. The seeds, peel, and leaves may all be used.”
