Oregano oil, made from the Origanum vulgare plant, has been used in traditional medicine for centuries. Its strength comes from compounds like carvacrol and thymol, which give it powerful antimicrobial effects. According to experts, these compounds help the oil “fight off bacteria, viruses, and fungi.”

Recent studies suggest oregano oil also works against parasites. It has shown effectiveness against “intestinal parasites such as giardia and pinworms,” supporting digestive health and improving nutrient absorption.

Beyond digestion, oregano oil may help the urinary tract. Its antimicrobial action “can help inhibit the growth of harmful bacteria that often cause infections,” offering a natural way to prevent and ease discomfort.

Despite its benefits, oregano oil is very concentrated and should be used carefully. If not diluted, it “can cause irritation,” whether applied to the skin or taken internally. Overuse may lead to side effects.

Because of its potency, experts advise consulting a healthcare provider before use, especially for people with medical conditions or on medication. Used responsibly, oregano oil remains “a powerful, natural remedy” that supports both digestive and urinary health.
