If you have a skin condition, are pregnant or breast-feeding, have epilepsy or asthma, are on a course of treatment with prescribed medication, or are in any doubt about any condition you may have, it is important that you seek the advice of a doctor or a qualified aromatherapy practitioner before using pure essential oils. We would also advise not to take any essential oil internally or to apply directly to the skin, and to use a patch test before using any essential oil for the first time.
