Essential Oils And Aromatherapy Supplies; Essential oils are the natural, aromatic volatile liquids found in plants that not only offer support for the body, they can be used to clean and purify your home, auto, workplace, etc. They are the most concentrated and potent of all plant extracts. These concentrated oils embody the regenerating, oxygenating, and immune-strengthening properties of plants. Essential oils are so small in molecular size that they can quickly penetrate the skin and enter the blood stream. In fact, essential oils can affect every cell of the body within 20 minutes and then be metabolized like other nutrients. All of our aromatherapy essential oils are therapeutic grade.
