Scented Serenity or Hidden Hazards?

Q: A friend has convinced my wife that essential oil aromatherapy is a “good-for-everything” natural remedy, and she has gone on this essential oil binge to improve her mood and relieve her anxiety. I’m skeptical and concerned. Is this safe? (We are trying to have our first child and want to be super-healthy!

A: Aromatherapy is defined as “inhalation or bodily application (as by massage) of fragrant essential oils (as from flowers and fruits) for therapeutic purposes.”1 Essential oils from plants, such as lavender or peppermint, are typically added to diffusers or baths, or applied directly to the skin. It is heralded as a natural way to feel better and may be helpful, but it is not without risk.

Multiple studies suggests that lavender essential oil is generally safe, especially when inhaled, and offers a simple, affordable way to promote relaxation.2 Many essential oils can be irritating to babies’ skin and are highly toxic to pets, even in small amounts. To protect children and animals, avoid using essential oils in areas they frequent, and store them safely out of reach. Undiluted essential oils can cause skin irritation for adults as well, especially cinnamon or peppermint. Using a neutral carrier oil, such as coconut oil, can help prevent these reactions. Some oils, such as tea tree and eucalyptus, have strong scents that may trigger headaches or allergic reactions, particularly in individuals with asthma or sensitive airways.

Even when inhaled, essential oils interact with multiple body systems, including the immune and endocrine (hormonal) systems, and may affect pregnancy, fetal development, young children, and people with allergies, autoimmune diseases, and cancer, so please consult your doctor.

Aromatherapy, in general, does not cure illnesses or address underlying health issues, although it often enhances surroundings with pleasant fragrances. Natural remedies have benefits, but some individuals may overly rely on aromatherapy for emotional and spiritual healing instead of praying, seeking professional help, scriptural advice, and God’s guidance, shifting focus from faith to physical tools. Also, concerns arise from its ties to mysticism, pagan rituals, and New Age spirituality, blending Eastern beliefs about energy and chakras. While such oils as frankincense and myrrh were used for anointing, worship, and healing under God’s guidance, biblical use of oils was rooted, not in mystical energies, but in faith in God (James 5:14). We sincerely hope this helps you. SHALOM!
