Myrrh Essential Oil
As used by the Three Wise Men. (and me) Antiseptic, fungicide and pain relieving. Yes, it's a bit pricey but is an archetypal oil used for millennia. It is used for purification and banishing harmful spirits. Combine it with Frankincense for full effect. I use them as follows for serious cleansing, Frankinsence opens the door and Myrrh boots bad energy through it. These two Trees are very powerful trees to have as your allies.
