Although rare, allergic reactions may occur when taking black haw. If you develop symptoms of an allergic reaction such as hives, closing of your throat; difficulty breathing; swelling of your lips, tongue, or face; stop using black haw at once and seek emergency care

Large doses of black haw may cause: nausea, dizziness, visual disturbances, reduced pulse rate, increased sweating and seizures.
