Eucalyptus oil, derived from the leaves of the eucalyptus tree, is gaining attention for its potential benefits in hydrating dry skin and alleviating joint pain. While the leaves themselves are toxic to humans, the essential oil can be safely applied when diluted with a carrier oil or lotion, according to experts.
Commonly used in aromatherapy, eucalyptus oil may help strengthen the skin's outer layer and lock in moisture, says skincare brand Kiehl's. Dr. Melissa Young of Cleveland Clinic explains that these concentrated plant extracts can be used in various ways, including inhalation, massage, and baths.
With a history of medicinal and ceremonial use by Aboriginal peoples for thousands of years, eucalyptus possesses anti-inflammatory properties. Researchers from Egypt and South Korea have found it beneficial for arthritis sufferers. A January study by pharmacologists in Egypt and Iraq noted its antimicrobial, anti-inflammatory, and analgesic effects, which help reduce inflammation and pain in wounds.
Eucalyptus oil is particularly useful during cold and flu season, as it can fight infection and ease congestion. Its strong, woody scent helps open nasal passages, making breathing easier and breaking down mucus. Additionally, a few drops diluted in vegetable oil can help prevent cold sores.
However, experts caution against direct application of undiluted essential oils, as they can cause rashes, burns, or allergic reactions. Pregnant women, people with asthma, and those prone to headaches or migraines should avoid eucalyptus oil. For most users, it can help reduce stress and promote relaxation. South Korean research from 2014 showed it decreased anxiety levels, and adding drops to a diffuser or hot water can create a soothing environment.
