Fill the pint jars with 1/3 Oregon Grape Root, 1/3 Barberry Root, and 1/3 Calendula Flowers. (Since the flowers are the largest of the herbs, include them last and do not compact the herbs.)
Fill the jar with sufficient Jojoba Oil to within a half inch of the rim of the jar. Make sure all the flowers and roots are submerged under the oil.
Allow the flowers and roots to steep in the oil for 6 weeks in a warm place. A sunny windowsill is fine.
After 6 weeks, place a mesh strainer over a bowl, empty the contents of the jar into the strainer, and allow the oil to drain into the bowl. DO NOT press down on the herbs.
Decant the oil into a bottle with a tight-fitting screw-on lid.
When you are ready to make the natural acne treatment salve, set up a double boiler on a stovetop set to its lowest setting.
Pour 1/2 cup of the infused oil into the top of the double boiler.
Add 1/8 cup of beeswax pellets or grated beeswax into the double boiler along with the oil.
Stir well and allow the beeswax to melt.
Once the beeswax has melted, turn off the heat and transfer the top of the double boiler to a heat-proof surface. If you are using the helichrysum essential oil, add the drops now to the warm oil and stir well to incorporate.
Carefully transfer the warmed oil to a 4 ounce jar or divide among small metal containers.
Once cooled, put the lid on the jar or metal containers. Store in a cool, dry place.
For best efficacy, use within one year.
