The compounds in oregano oil work together to provide the antimicrobial effects this oil is so well-known for. Carvacrol is its most important component, and is responsible for many of its health benefits. Carvacrol has powerful antimicrobial properties, and has been shown to help break through the outer cell membranes that help protect bacteria from your immune system.
Pure oregano oil can either be applied topically or ingested, depending on the condition you’re using it for. However, I advise against using the oil full-strength, as it can irritate your skin. Do not apply it to broken skin and open wounds as well.
Buy oregano oil is meant for short-term use only, and, if using orally, should be taken in small doses of four to six drops for only seven to 10 days.
