We assembled this blend at the request of a very successful naturopathic clinic to help protect against harmful electromagnetic frequencies. I say “assembled” because it combines our Sauna Synergy (Eucalyptus, Pine, Cedar, Frankincense, Lemon, Palo Santo, Rosemary verbenone, Myrtle, Hyssop & Ylang) with our Shield Synergy (Cedar, Vetiver, Sandalwood, Frankincense & Sage) then we add St Johnswort and Tobacco essential oil in our base of Fractionated Coconut oil and Jojoba.
