Speak to a doctor before starting aromatherapy if you have one of these chronic illnesses:asthma, respiratory allergies or chronic lung disease and skin allergies. In pregnant women, some aromatherapy oils may cause early contractions. Children under 5 can be very sensitive to aromatherapy oil and should avoid it. Never use the oils near the eyes or mouth. Aromatherapy is no replacement for traditional medical care.
