What are the risks of taking oregano or oregano oil?

ANSWER

Experts agree that oregano is safe when used for its intended purpose -- adding flavor to food. But they don't know if using it for medicinal reasons is safe.

In large doses, oregano oil may be toxic -- and even lethal. Oregano may have diuretic effects. Large amounts of oregano can upset the stomach. And oregano oil may cause rash if you put it on your skin.
