An oil is “essential” in the sense that it contains the “essence of” the plant’s fragrance—the characteristic fragrance of the plant from which it is derived. In order to ensure you’re getting the most effective therapeutic benefits out of your aromatherapy routine, it is important to make sure your essential oils are pure, top-quality products. While other companies may cut their oils or use sub-par ingredients in order to sell for a higher profit, Beaver Brook uses optimal and honest extraction methods while guaranteeing that each essential oil is derived from 100% all-natural plant sources such as flowers, leaves and roots.
