Aromatherapy Risks

Aromatherapy uses aromatic, plant-based oils to promote body, mind and spirit balance. It is used for various reasons, including stress, pain, anxiety and depression relief. Though aromatherapy is generally considered safe and may provide benefits, according to the Mayo Clinic, it can also pose numerous risks. Aromatherapy should not be used to replace doctor-prescribed treatment. Doctor's approval and guidance is suggested prior to utilizing aromatherapy, particularly in people with medical conditions, for best results.

Skin Reactions

Aromatherapy increases risk for skin reactions, such as rash, skin irritation and skin burning, in some people. According to the National Cancer Institute (NCI), skin problems are most common after long-tern use or exposure to certain oils. When oils, such as citrus oils, are applied directly to the skin prior to sun exposure, sun sensitivity, irritation and sunburn may develop. In some cases, skin rashes occur as an allergic reaction to particular oils.

Hormonal Effects

Aromatherapy may adversly impact hormone levels. Aromatherapy oils made from tea oil or lavender may affect the body similarly to the female sex hormone estrogen. They may also reduce the effects of male sex hormones known as androgens, according to the NCI. These hormonal shifts increase risk for reduced sex drive (libido) and mood swings. Due to potential hormonal side effects, long-term use of lavender and tea tree oil may result in breast enlargement in pre-pubescent boys.

Drug Interaction

Essential oils may alter the effectiveness of certain medications. In an interview with BBC News, nurse and aromatherapy professional, Kath Ryan, explained that essential oils affect people differently and may interfere with medications. Since aromatherapy practices are not regulated or tested for safety or effectiveness, practitioners may not be aware of drug interactions. For this reason, Ryan suggests seeking qualified, trained aromatherapy professionals. Doctor's approval for people taking medications of any kind is also suggested.

Headache and Nausea

Essential oils are extremely condensed and potent derivatives of plants. For this reason, aromatherapy may cause headaches and nausea in some people, according to the "The Desktop Guide to Complementary and Alternative Medicine: An Evidence-Based Approach," by Edzard Ernst. Strongest-smelling oils and excessive or long-term use may exacerbate these effects. Headaches and nausea may occur separately or simultaneously. People prone to headaches or nausea and those seeking aromatherapy for relief of pain or digestive problems may find the treatment ineffective or problematic due to these effects.
