Tea Tree Oil is awesome, we use it for everything from acne to headaches! You can purchase it at Walmart in the vitamin section or through Puritan's Pride. Here is the recipe for the rub. You can use the rub for congestion like Vic's Vapor Rub or for aches and pains like Icey Hot.
Mix a few drops of Tea Tree oil with about 2 tablespoons of olive oil. Use right away.
You use it straight for these ailments (test your skin first for any irritations);
White & Black Heads: apply to problem with a Q-tip every night for a week or so
Skin tags & warts: This works! Apply it to the tag or wart 3 times day for a week and it should fall off, if not, then continue it for another week or so
Sty: I have used this treatment and it works well but be very careful if it is close to the eye. Just apply to the sty with a Q-tip for about 1-2 weeks
Toe Fungus: Apply straight to the nail every night for a week
Athletes foot: Mix a few drops in a tub of warm water and soak every night for about a week
