At Aroma Remedies I offer blends of essential oils formulated to control different types of pain. I presently have over 50 blends that I know are effective. All of the essential oil formulas I offer work through inhalation. Simply take two or three breaths and if they are going to work for you there should be a reduction in pain within 30 seconds and carry an 80% success rate. Normally, if one formula works for you they will all work.
