Use a double boiler, or make one by setting a glass jar in a medium pot with 1-2 inches of water. Bring the water to boil then turn down to med/med-high.
Add the olive oil, coconut oil, and beeswax.
When those are melted together, add the turmeric and comfrey and let them simmer for 2 hours.
Stir occasionally.
Remove from heat, strain the mixture, and add essential oils.
Store in a glass container.
