My guest is Dr. Chris McCurdy, PhD, FAAPS, professor of medicinal chemistry at the University of Florida and a world expert on the pharmacology of kratom and other plant-derived medicinal compounds. We discuss kratom’s wide-ranging effects, including its use for boosting energy, enhancing mood, managing pain and as a potential opioid substitute, while also explaining its critical safety concerns and addictive potential, especially for kratom-derived/isolate products. We also discuss plant-based compounds more generally for their potential benefits and risks. Dr. McCurdy offers a balanced perspective on kratom and other plant-based and naturally occurring medicinal compounds, highlighting and contrasting their promise for human health with potential serious risks.
