Basil essential oil contains a number of compounds thought to enhance health. These compounds include linalool, a substance shown to reduce stress in several scientific studies.
How Does Basil Essential Oil Work?
In aromatherapy, inhaling the aroma of basil essential oil (or absorbing basil essential oil through the skin) is thought to transmit messages to a brain region involved in controlling emotions. Known as the limbic system, this brain region also influences the nervous system. Aromatherapy proponents suggest that essential oils may affect a number of biological factors, including heart rate, stress levels, blood pressure, breathing, and immune function.
Health Benefits of Basil Essential Oil
While preliminary research suggests that basil essential oil may offer certain health benefits, there is currently a lack of research testing the health effects of aromatherapeutic use of geranium essential oil. For example, several laboratory studies published in the past decade indicate that basil essential oil may possess anti-cancer, antifungal, and antibacterial properties.
In addition, a study published in the journal Biomedica suggests that basil essential oil may aid in the treatment of acne. For the study, 28 people with acne were assigned to eight weeks of treatment with one of four formulations: a blend of orange and basil essential oils, keratolytic medication (a type of medicine designed to remove lesions from the skin), essential oils mixed with acetic acid (a compound sometimes used as an ingredient in skincare products), or keratolytic medication with acetic acid. By the study's end, all groups showed improvements in acne. The greatest improvements were seen in patients treated with the acetic acid mixtures.
It's important to note that none of these studies tested the aromatherapeutic use of basil essential oil, and that more research is needed before basil essential oil can be recommended in treatment of any health condition.

In addition, basil essential oil is said to enhance mood, improve digestion, increase alertness, and soothe muscle aches.
