For a chest rub with soothing beeswax, melt 1/2 ounce of beeswax with 1/4 cup of a carrier oil. While the beeswax is still soft, stir in 30 drops peppermint, 15 drops eucalyptus radiata, and 15 drops rosemary essential oils in the top of a double boiler.
The best ratio is up to 6 drops in 5 ml of carrier oil. Mix well and dab on the blister using a cotton-tip applicator.

With trial and error you can usually find one or a combination of a couple of essential oils that work best for you.
