Add all the ingredients , except for the essential oils into your double boiler or a pan inside of another pan of water to create a makeshift double boiler.
Heat on Medium, until all ingredients are liquid.
Turn heat down to low, and add the essential oils.
Stir really well.
Pour the liquid carefully into small salve containers of your choice. I prefer small tins.
Let it cool for 2-3 hours or overnight, and then place the lids on.
Notes
Only use high quality essential oil that can be used on skin
