Begin by gently melting the coconut oil, the beeswax pellets, and the menthol crystals in a double boiler.
While the mixture is melting, measure out your essential oils in a small glass, such as a shot glass.
Once the beeswax mixture has melted, turn off the heat and allow it to sit a few minutes to cool slightly.
Pour your essential oils into your beeswax mixture and stir it with a wooden chopstick. Immediately pour it into your glass jar. Seal and label.
To use, apply the balm to areas of pain, keeping it away from your eyes. If your mixture thickened too quickly, warm it up briefly to liquify.
