How do you create the most comprehensive and effective tension formula? We blended the best characteristics of two Edgar Cayce tension formulas: Peppermint Spirits and Temple Healer into a base of Aura-Tone with Arnica plus lavender essential oil in a convenient roll-on applicator! Massage into neck muscles, temples, forehead and occipital ridge (behind your ears and at the base of your skull) to help release persistent aches, cool head discomfort and sharpen focus.
