11 Aromatherapy Essentials from India: Uses and Benefits

7. Oregano — Powerful antimicrobial with careful use only

Oregano oil is a potent antimicrobial that contains carvacrol and thymol, compounds shown in lab studies to fight microbes. Because of its strength, oregano is used cautiously in traditional and modern contexts—often in highly diluted topical formulas or as an ingredient in household disinfectants. For topical use, never exceed a 1% dilution without professional guidance; a 0.5–1% dilution is safer for localized adult application, meaning roughly 3–6 drops in 30 ml carrier oil. Avoid applying oregano to broken skin and never use it undiluted. Oregano is not for children, pregnant or nursing women, or people with very sensitive skin. Some people consider oregano for internal use, but this should only occur under clinical supervision. For home use, reserve oregano oil for problem cleaning tasks or short-term focused topical use, and always do a patch test. Purchase high-quality Origanum vulgare oils with transparent testing and clear botanical names. (Sources: Veda Oils; Pure Oils India.)
