Melt cocoa butter and beeswax over low heat in a double boiler. I used a large pyrex measuring cup as the double boiler and with a small amount of water in the pot.

Add the shea butter until melted (adding the shea butter last will help prevent it from getting grainy once it has cooled).

Remove from heat. Stir in peppermint essential oil.

Immediately pour into lip balm tubes (or jars/pots). Allow cooling before adding caps. Let sit at room temperature until solid, which usually takes 2 to 4 hours in a moderate climate.

Add a label with glue stick or adhesive tape runner.
