Melt the coconut oil and shea butter over low heat. Use a double boiler or a quart mason jar sitting in a few inches of water in a pot.
Add the dried calendula and chamomile to the oils. Place a lid on the mixture and keep the pot over low heat for 20 minutes to an hour, depending on how desperate you are for itch relief.
Put cheesecloth in a sieve and filter the herbs from the oil into a bowl that you can set the sieve on to drain. You can discard the herbs and the cheese cloth.
Wipe down the double boiler or the quart jar, so that bits of herb are removed and pour the filtered oil back in.
Return the heat to low and add the honey and stir.
Remove the mixture from the heat and add the baking soda, bentonite clay, witch hazel and apple cider vinegar. Continue to stir.
Now add the peppermint and tea tree oil and stir.
Allow it to cool, then transfer the cream into a jar with a tight-fitting lid or just let the mason jar cool if that is the method that you used.
As soon as the mixture is cool enough to touch, use it!
