Comfrey & the PA Puzzle - Short Course

Learn about the different Comfrey species & cultivars, their synergistic phenolic constituents & the pyrrolizidine alkaloids (PA): what they are & why they matter. Is Comfrey safe? What about leaf vs. root? What is the spectrum of PA toxicity? What are they soluble in? Can you absorb them through your skin? How does the liver metabolize them? Can they really cause liver disease? How much is too much? We'll dive into phytochemical detail to answer these questions and give you the tools you need to make a rational risk/benefit analysis of this traditional medicinal plant. Includes detailed handouts with links to resources, an illustrated PowerPoint deck, a fun self-assessment quiz, and two recorded 2-hour Q&A Webinars with Lisa Ganora & Kat Martello!
