Essential oils, even in a pure and unadulterated state, can cause harm, if the essential oil is not correctly identified and the adverse effects are not known; in addition, an essential oil extracted from a plant may be chemically different to the plant in its natural state. Therefore, some plants used in plant medicine may be harmless but, in essential oil form, may be dangerous.
