Combine the olive oil and the coconut oil, along with the butter and beeswax in either a double boiler and slowly heat on the stove.
*Side note here* don't microwave you will kill many nutrients you want to be present in your salve.
When all your items have melted together remove from the heat. Add vitamin E oil and essential oils. Remember to pour into your container while it's warm, it will harden but should stay at a salve like consistency.
