I developed severe candida infections in my mouth several weeks after getting 7 amalgams removed. It seems like am finally getting the infections under control with grapefruit seed extract. I am now taking 6 drops in 8 ounces of water 8 times a day. At firat I just rinsed my mouth with grapefruit seed extract. That wasn't doing enough. Now I swallow the grapefruit seed extract, and use hot salt water and peroxide to rinse my mouth.
