(1.) Only 1% of the essential oils in the market place are therapeutic. Non-therapeutic oils are not distilled properly and are often cut or diluted with synthetic products to reduce their price – and moreover, their effectiveness.
A prime example of this problem is with a product called Rose Geranium, purported to be the very precious and expensive rose, Rosa damascena. However, it costs at least 20 times less than Rose and does not have its same properties.
(2) Most essential oils and essences should never be used pure. Some have caustic properties which can be harmful, and research shows that a blend of oils is a more effective treatment.
(3) Essential oils can be ingested in 3 ways: by inhaling them, by using them on the skin, and by mouth which is not recommended without professional advice. Your aromatherapist can advise you of the most appropriate and efficient method for using the oils.
The consumer, when inhaling essential oils, should be particularly careful because not all essential oils should be inhaled. Also, essential oils or essences should not be burned or used in cheap glass diffusers. The appropriate diffusers have a very special hand-blown glass. It has many bubbles on the neck of the glass to explode the molecules which less expensive diffusers do not have. Consequently, the consumer uses more essential oils and might do himself harm over time. Pottery diffusers are an excellent substitute to those mentioned above when used with the appropriate essences.
(4) Only purchase oils which are biologically and chemically defined. This means you should know the essential oil’s complete Latin name, the part of the plant (flower, leaves, stem, bark, etc.) from which it is distilled, and the geographical location from which the plant is harvested. There exist about 10,0000 aromatic chemically defined components in the aromatic plants used for aromatherapy. These components have properties that give the essential oils their therapeutic indication. Merely using an oil labeled “rosemary”, for example, does not give the consumer enough information to treat a condition. There are several “rosemaries”. Each has different properties and some have diametrically opposed effects which can be harmful to your health.
