Herbal medicines typically contain a number of active components. As a result, some provide multiple benefits and some a mixture of benefits and adverse effects. Hawthorn, kava, and saw palmetto fall into the first category and licorice into the second. The problems with licorice can be largely avoided by using a deglycyrrhizinated preparation.
