Welcome to the Center for Research on  Botanical Dietary Supplements ("Botanical Center") website. The Botanical Center is an affiliated member center of the Nutrition and Wellness Research Center (NWRC) at Iowa State University.

 

The Botanical Center, in collaboration with the University of Iowa, is studying three of the most widely used botanical supplements, Echinacea, Hypericum (St. John's Wort), and Prunella (common selfheal).  Learn more about our research here.

 

Our goal is to improve our understanding of the factors that contribute to health benefits, and to optimize these supplements for study in future clinical trials.

 

The Center is funded by the National Center for Complementary and Alternative Medicine (NCCAM) and the Office of Dietary Supplements (ODS).
