Fill the bottom of a small saucepan with about 1 1/2 inches of water. Heat water over low heat. Put small glass dish in center of saucepan.

Pour olive oil and beeswax into the small glass dish. Continue to heat on low until beeswax has fully melted, stirring frequently. Add in cayenne pepper and ginger powders. Mix well.

Remove oil mixture from water and heat source. Let cool slightly, then add in lavender oil, peppermint oil, and vitamin e oil (if using). Stir.

Immediately after mixing in essential oils, pour salve into storage tin. Set aside to allow the homemade muscle rub salve to cool and set.

Once salve is room temperature and has set, store in fridge for up to 3 - 6 months.
