Essential Oils are useful in the practice of aromatherapy. Essential oil is not actually an oil, but the natural product extracted from the bark, flower, fruit, leaf or root. They deliver positive benefits to the body through smell and direct absorption into the skin. Benefits of essential oil include soothing, calming, stimulating, refreshing, centering, and warming to the system. They are sourced from all over the world in their purest state. Essential Oils are extremely potent and should never be used directly on the skin, as the liquid may cause irritation to the skin.
