Essential Oils are useful in the practice of aromatherapy. Essential oil is not actually an “oil” in the traditional sense of the word. Essential Oils are all natural products derived from the plant (bark, flower, fruit, leaves, root). They can deliver positive benefits to the body. Benefits of essential oil include soothing, calming, stimulating, refreshing, centering, and warming to the system. They are sourced from all over the world and are in their purest state, they are extremely potent, and should never be used directly on the skin, as the essential oil may cause irritation.
