Licorice Affects Blood Pressure

Q. I have read your articles on licorice raising blood pressure, but you don’t state if it is black licorice or both red and black licorice.

I have never suffered from high blood pressure and I enjoy red licorice once in a while. I don’t notice any side effects from eating it. Is it safe?

A. Red licorice is totally safe. It doesn’t contain the ingredient (glycyrrhizin) found in black licorice that may raise blood pressure.
