Unique in the pantheon of plant medicinal preparations, essential oils capture both the substance, yuan qi and the spirit, wei qi, of a plant. Inherent in plants in the same way that blood is inherent to the human body, oils carry the nutrients and the genetics to every corner of the plant. When we extract oils from plants and plant parts, we change both the concentration and nature of a plant's natural oil content, yielding a compact, powerful, and previously unborn substance.
