Scents have an effect on our mind and body, evoking memories and arousing the senses. Certain essential oils in turn have the ability to relax, stimulate, or create balance between the body and mind. At NOW® Solutions, we take the quality and purity of our essential oils very seriously. We go to great lengths to ensure that every oil we produce is brought to you in a manner that's both scientifically and environmentally responsible.
