Safety Information for Use of Essential Oils and Dilutions
This is a guide only and for detailed information please contact either myself or a qualified aromatherapist. Please ensure that you obtain diagnosis from your GP and check with them if you are on medications or are in any doubt about the use of oils with your medical condition
Whilst there are warnings about the use of essential oils there is actually little research to back these up. However, care should be taken when using essential oils as they are highly concentrated. When using an oil for the first time it is wise to over dilute it to check that you do not have a reaction.
Primarily the advice is given relating to use on the skin but consider the information too if using as a room fragrance or for magical purposes. Many oils are also used in commercial products such as toothpaste, sweets and so on. You may find that you react to something on your skin but not when eating it and vice versa.
It is not recommended to consume essential oils without specific knowledge of the topic so please read these advice notes as relating to use on the skin or in magic.
Take extra care if using oils for the elderly or children who will have much more delicate and sensitive skin. Always overdilute in this instance.

If you are using the oils for magical workings remember that you may well get the oil on your hands so take the warning advice into account.
