Grapefruit Seed Extract is great stuff. I used to use it on my gums with a gum stimulator to cure gingivitis too :)
Grapefruit Seed Extract
Grapefruit seed extract kills bacteria, fungi and viruses. I have used it for everything from common cold, stomach virus, UTI, to strep. Dries up poison ivy, disinfects household items, clothes, towels, etc. I have it on hand always. I put ten drops in an empty capsule. But you can put in water or juice and drink. It's very bitter though .. it's an amazing product.
