Oregano leaves yield a concentrated oil, standardized to active compounds like carvacrol and thymol. This oil supports immune function and helps maintain a healthy microbial balance in the digestive tract.
Take oregano oil as liquid drops or capsules. A meal helps reduce stomach upset. Dilute it in a carrier oil for topical use, but oral supplementation remains the usual choice for internal benefits.
Do not use during pregnancy or breastfeeding. If you take blood thinners like warfarin, speak with a doctor before use because oregano oil can raise bleeding risk. High doses may upset your stomach, and you should stop taking it at least two weeks before planned surgery.
