Research on the efficacy of aromatherapy, the therapeutic use of essential oils extracted from plants, is limited.
However, some studies have shown that aromatherapy may have health benefits, including:
Relief from anxiety and depression
Improved quality of life, particularly for people with chronic diseases
Sleep improvement
Smaller studies suggest that lavender oil aromatherapy can help:
Reduce pain for people with knee osteoarthritis
Improve the quality of life of people with dementia
Reduce pain for people with kidney stones
Essential oils used in aromatherapy are typically extracted from various parts of plants and then distilled. Highly concentrated oils can be inhaled directly or indirectly, or applied to the skin with massages, lotions, or bath salts. Some essential oil manufacturers have oils that can be ingested, but research on the safety and effectiveness of this method is extremely limited.
Aromatherapy is believed to work by stimulating the olfactory receptors in the nose, which then send messages through the nervous system to the limbic system, the part of the brain that controls emotions.
Many essential oils have been shown to be safe when used as directed. However, essential oils used in aromatherapy are not regulated by the Food and Drug Administration.
When oils are applied to the skin, side effects can include allergic reactions, skin irritation, and sensitivity to the sun. Additionally, more research is needed to determine how essential oils might affect children and pregnant or breastfeeding women, as well as how the oils might interact with medications and other treatments.
If you are considering starting aromatherapy, consult your doctor and a trained aromatherapist about the potential risks and benefits.
