This is the most effective method of using the oils, combining their properties with the therapeutic power of touch. The oils should be diluted with an odourless carrier oil, such as grapeseed, sweet almond or peach kernel. There is no scientific evidence that oils are absorbed through the skin and then into the bloodstream. Dermatologists who have done similar experiments also show that oils do not go through the skin. The skin is the largest organ of the body and is designed to keep out contaminants not let them in.
Medical patches use specially designed synthetic compounds to go through the skin.
It has been shown that those oils that do have penetrative affects are also those that are likely to be sensitizes or irritants thereby showing that the skin is working in stopping contaminants getting through the skin. Using oils in baths is a simple, effective and pleasant way to relax and receive the therapeutic effects. Water itself has a therapeutic value which enhances the powers of the oils. To use, add 6 to 10 drops of essential oil to the surface of the water which has already been run, add no other substances, e.g. foam or bath oil, then immerse yourself for about 20 minutes, while you inhale the vapour. All essential oils are antiseptic and evaporate easily, so they make very good air-fresheners.
