Also known as: Oil of oregano, Origanum vulgare oil
Oregano oil is rich in carvacrol and thymol, phenolic compounds with potent antimicrobial, antifungal, and antioxidant properties. It is primarily used for immune support and upper respiratory tract infections.
Oregano oil is a steam-distilled essential oil from Origanum vulgare containing high concentrations of the phenolic monoterpenoids carvacrol (60–80%) and thymol (5–20%). Carvacrol disrupts bacterial cell membranes by integrating into the lipid bilayer, causing leakage of cellular contents. This mechanism provides broad-spectrum antimicrobial activity against gram-positive and gram-negative bacteria, including antibiotic-resistant strains such as MRSA. In vitro and animal studies demonstrate antifungal activity against Candida species comparable to nystatin. Oregano oil also shows antiviral properties by interfering with viral envelope fusion. Its antioxidant capacity is among the highest of all herb-derived essential oils, attributed to carvacrol's ability to scavenge reactive oxygen species. Oregano oil is available as enteric-coated softgels for internal use and diluted preparations for topical application. Due to its potency, it should be used in short courses and properly diluted.
Carvacrol and thymol disrupt microbial cell membranes, showing activity against pathogenic bacteria including E. coli, Salmonella, and MRSA in laboratory studies. A small clinical trial showed oregano oil reduced intestinal parasitic infections.
Oregano oil demonstrates significant antifungal activity against Candida albicans and other fungal species in vitro. Carvacrol inhibits biofilm formation and hyphal growth of Candida.
