Grapefruit Seed Extract

Can you give me any information about grapefruit seed extract?

Although some "grapefruit seed extract" products are effectively antimicrobial and antifungal, it appears from research articles that the effective chemicals in these products are not natural and not from the grapefruit seed, but from the preservatives used to produce the products.
You can contact the manufacturer of any of the grapefruit seed extract products that you are interested in to get details of their processing techniques, the active components in their products and their health safety information.
