|Synergies are blends of two or more essential oils for a specific purpose. They are easy to use and take the guesswork out of blending. Our Synergies are made with pure, undiluted essential oils and should be added to body products such as massage oils, bath salts, bath gels, and lotions. Some are ideal for electric diffusers, room sprays, facial steams, and humidifiers. Do not apply Synergies directly to the skin.
