Larry is a plant geneticist and breeder whose lab uses genomic tools to better understand hybrid vigor, sex determination, and pest and disease resistance in shrub willow bioenergy crops. More recently, he has been leading Cornell’s hemp research and extension team and has initiated a long-term breeding and genomics program to develop new hemp cultivars for New York State. He received his B.S. in Biology at Cornell University, Ph.D. in Genetics at Michigan State University, and was an NSF Postdoctoral Fellow at UC-Davis.
Course Overview
This course is a starting point for the study of medical ethnobotany, which involves the plants found in a particular place and how they can be used to treat illnesses. By examining the historical applications of plant-based medicines, the compounds that are commonly found in plant-based medicines, the potential safety considerations when using plant-based medicines, and how to critically evaluate the labels and packaging of plant-based medicines, you will be prepared to understand the applications of these types of medicines and what information people need to be aware of if they plan on using them. This is not a replacement for consulting with a physician; it is intended as an exploration of alternatives that you may not have considered. In this course, and each course that follows, we recommend that you consult with a medical expert before implementing any medicinal plants into your own personal health plan.
