Essential Oils: Healing One's Self with Powerful Essential Oil Recipes Essential oils are the therapeutic and fragrant essences extracted from herbs, bark and flower leaves. Every essential oil has unique healing and therapeutic properties that have been acknowledged by their use all over the history. They can be used in baths, massages, blends, and inhalations. Choose the essential-oil that appeals to you and start to experience the amazing world of essential oils. Essential-oils are the core or essence of plants. They are different from fragrance oils. Essential oils are derived from real plants; fragrance-oils are synthetically created fragrances or contain artificial substances and they do not provide the therapeutic and healing benefits which essential-oils offer.
