Derived from Origanum vulgare leaves, oregano extract packs higher levels of carvacrol and thymol than the dried culinary herb. People take it orally to ease digestive discomfort and bolster the immune system. The extract also gets applied to the skin for cosmetic or soothing purposes.
Liquid drops and capsules are common forms, often taken during cold season or after eating. The oil can be diluted for skin application.
Caution: Oregano extract may interact with blood-thinning drugs. Large amounts are not recommended during pregnancy. Stop use before any scheduled surgery.
