Q: I am borderline for high blood pressure. Some products contain warnings about using them if you have this condition. Why?
A: Some products contain licorice (glycyrrhiza) and one company that we know of has warnings on the label because of this. Long term use of large amounts (3-9gms per day) of licorice may cause high blood pressure. However, other companies choose not to do this since the amount of licorice in the product is extremely small and unlikely to cause any problems.
