Can oil of oregano cause petechiae?

While oil of oregano is generally considered safe for most people when used appropriately, it can cause allergic reactions or irritations in some individuals. In rare cases, these reactions may lead to conditions like petechiae, which are small, pinpoint-sized red or purple spots on the skin caused by minor bleeding. If you experience petechiae after using oil of oregano, it’s advisable to consult a healthcare professional to determine the cause and appropriate action.
