You will need
Beeswax (1-2 ounces)
Essentail oil (optional)
Gather all your ingredients and cut the beeswax into smaller pieces if you have a block of it. Put the wax into a smaller saucepan (one that you won't mind getting wax caked to it) and get a bigger saucepan and fill it with water. Set the heat on the stove to med high and get your water boiling. Once it started to boil you will set the pan with wax right on top of the boiling water and now you have a double boiler.
Once you get the mixture just right to your liking then you will add the essential oil pick one that you like but if you have skin irritation I recommend using one with antiseptic properties in it so it won't irritate your skin. I myself used dragons blood because I love the smell.
Your done, that's it. You will let it sit for about an hour to cool completely. Keep in mind you don't have to use Calendula or Plantain. You can use any infused oil you like to make your a salve that suits your skin needs. I chose those two oils because of the properties in them are good for so many skin ailments. Feel free to mix it up and use whatever infused oils you want.
