Melt the cocoa butter, castor oil, and beeswax together in a double boiler or an aluminum bowl inside a pan filled with warm water on low to medium heat.
Once melted add the liquid honey.
Mix well until it is foamy for a few minutes.
Add the essential oils if desired.
Mix well for a few seconds.
Take off the heat and pour immediately into a 1 oz nice container.
Let cool for 1 hour and the lip balm will solidify.
This recipe makes 1 oz and can last up to a year (but also depending on the shelf life of the oil and butter you use)
