All of our Aromatherapy & Environmental Blends are made using only 100% pure essential oils and absolutes. These are true, unadulterated botanical oil blends and are not diluted with carrier oils. They are blended together to form unique powerful synergies and can be used by the drop in diffusers, atomizers, perfumes, potpourris, candles, baths or massage oils. These oils are highly concentrated and should never be used directly on the skin without first diluting with a carrier oil! We highly recommend consulting an aromatherapy book which explains the benefits and contraindications of each oil. Keep a variety on hand for your changing moods and needs! Droppers, pipettes and/or orifice reducers are sold seperately ( see Bottles & Supplies). For information on Essential Oils see EO Main Page. For safety info see Safety Chart.
