Almost anyone can enjoy the benefits of an aromatherapy oil, but certain individuals, such as pregnant women, persons with allergies, and those with respiratory conditions such as asthma should only use essential oils for aromatherapy under the guidance of a trained professional.
Keep in mind that essential oils are highly concentrated botanical extracts and should never be ingested or applied to skin at full strength. Consult a professional aromatherapist or an accredited reference on aromatherapy for advice on these uses.
