Avocado oil is high in vitamin E, which is essential for skin and hair health. The fruit also has more potassium than a banana, and helps the body maintain its fluid and electrolyte balance. Avocados also have the ability to boost immune system function. The oil of avocados may also have antiseptic properties, according to a June 2010 issue of the "Revue de Stomatologie et de Chirurgie Maxillo-Faciale" Journal.
Because of its antibacterial properties, avocado oil could be included in some mouthwashes, as the oil can eliminate the toxins that cause bad breath and tooth decay. The Journal of Periodontology also asserts that avocado oil can prevent gum disease by decreasing inflammation.
Avocado oil is also edible and contributes to the health of the heart. The Journal of the American College of Nutrition published a study in February 2003 stating that avocado oil is comparable to olive oil in terms of providing heart health. In a study, animals who were fed avocado and corn oil had the highest density of lipoprotein after a 90-day period. The animals were also fed olive and coconut oil during the study.
The oil can also be used as a healthy alternative to salad dressings that are high in fat.
