This ethnobotany course delves into the fascinating world of plant chemistry, exploring the diverse array of chemical compounds plants produce and their significance in traditional medicine and human use. From the fundamental process of photosynthesis to the complex biosynthetic pathways leading to unique secondary metabolites, you will gain a deeper understanding of how plants have evolved to thrive and interact with their environment. We will uncover the secrets behind the medicinal properties of plants, examining classes of compounds like phenols, alkaloids, terpenoids, and glycosides. You will learn to identify key structural features that influence their pharmacological activity and explore how they contribute to the effectiveness of traditional remedies.
Through case studies of well-known medicinal plants, we will unravel the intricate relationship between plant chemistry, traditional knowledge, and modern medicine. We will discuss concepts like pharmacodynamics, pharmacokinetics, and synergy, highlighting the complexity of plant-based medicines and challenging traditional reductionist approaches. This course emphasizes the critical importance of preserving biodiversity and indigenous knowledge for future drug discovery and the sustainable use of Earth’s precious plant resources.
What you’ll learn:
- Fundamentals of Plant Chemistry: Photosynthesis, primary and secondary metabolites, biosynthetic pathways
- Medicinal Plant Compounds: Phenols, alkaloids, terpenoids, glycosides, and their pharmacological activities.

Dennis McKenna´s research has focused on the interdisciplinary study of Amazonian ethnopharmacology and plant hallucinogens. He has conducted ethnobotanical fieldwork in the Peruvian, Colombian, and Brasilian Amazon. His doctoral research (University of British Columbia,1984) focused on the ethnopharmacology of ayahuasca and oo-koo-he, two tryptamine-based hallucinogens used by indigenous peoples in the Northwest Amazon. He is a founding board member of the Heffter Research Institute, and was a key organizer and participant in the Hoasca Project, the first biomedical investigation of ayahuasca used by the UDV, a Brazilian religious group. He is the younger brother of Terence McKenna. He is currently Assistant Professor in the Center for Spirituality and Healing at the University of Minnesota. He is the president and founder of the McKenna Academy of Natural Philosophy.
