In the years since I have started using tea tree oil, the number of uses has increased.
It is an excellent antiseptic, in fact, I use it successfully on canker sores, clears up even the most aggressive in a day or 2. (To use it this way, shake a bottle of the oil, daub the end of a q-tip on the inside lid. Dry the area of the canker sore, apply and hold for several seconds, then hold the sore out and let the oil dry. I told the mother of a child about it, she tried it and only needed 2 applications to heal up a very large, open sore. Less than 24 hrs. was all it took.)
Any; acne, scrape, cut or other open wound heals quickly after application, and only a little dab will do you!
Nanc's daughter, zgirl, had a swollen gum, near a tooth that had lost it's filling. Since it was the weekend, a dentist just wasn't available. At a nearby small store, Nanc picked up some freshly made colloidal silver with a small amount of tea tree oil in it. The swelling and pain went down, and stayed down until zgirl could get into the dentist on Monday.
Also, a little bit on a cotton ball, can help dry up acne or boils before they get too big and really painful and obvious.
