Roots of Medicine is an interdisciplinary project featuring a collaboration between the College of Pharmacy, Hardin Library for the Health Sciences, and community members. It joins the College of Pharmacy garden you see before you with historical resources from the John R. Martin Rare Book Room at the Hardin Library for the Health Sciences and databases from the National Institutes of Health. Each plant has an identification tag with the common name, species name, and a QR code. If you point your phone’s camera at the QR code and click the link that appears, you will be taken to a webpage with information on the plant’s historical and modern medicinal uses and a feed of the most current research. We invite you to walk the garden, take a journey through time, and explore the Roots of Medicine!
