Essential oils are the volatile liquids extracted from plants, such as their seeds, bark, leaves, stems, roots, flowers and fruits. The oils of the plant are the plant's essence and keep the plant healthy and resistant. Essential oils were man's first medicine, which is an important fact to consider. Essential oils are potent antioxidants and effective immune system supporters. They are detoxifying, regenerating, oxygenating and stimulating, serving as chemical messengers for the body, prompting your body's innate intelligence to re-balance itself. In addition, they are multi-functional and adaptive to what the body needs at the time, but have the ability to be active in the body for up to a week's time.
