In a double broiler (or a pot filled a quarter of the way full with water and a heat-safe bowl over the top), melt the coconut oil. Add the dried calendula. Place a lid over the top of the double broiler. Over medium heat, infuse the herbs in the oil for 30 minutes.
Separate the herbs from the oil by straining the oil through a fine mesh sieve. Discard the calendula (or compost in a garden). Wipe the double broiler to remove any leftover herbs. Return the infused oil to the double broiler. Bring the heat back to medium-high (enough to get the water underneath boiling). Add the shea butter and beeswax to the infused oil, and stir until melted.
Remove the pan bowl from the heat. Add the baking soda and benonite clay to the liquid, and stir until the mixture resemble mud (really, mud!). Add the witch hazel and essential oils, stirring to combine.
Pour the cream into a jar (this recipe will make enough to fill a 4-ounce jar). Within minutes the cream will solidify into a spreadable lotion.
