In recent years, there has been much interest in interactions between botanicals and drugs, that is, the ability of medicinal “herbs” to influence the pharmacokinetics (absorption, metabolism, or excretion) of pharmaceuticals. This interest was sparked by the rising awareness that the prevalence of herbal supplement use was high in the general population and higher yet in patients with chronic diseases requiring regular intake of a variety of medications. Reports of life-threatening consequences resulting from herb-drug interactions further underscored the urgent need for a better understanding of these interactions.
