Herbal Constituents & Make Better Medicine
Herbal Constituents & Short Courses
Herbal Constituents 1
registration is now closed until Summer 2025
Herbal Constituents goes in-depth to explore the nature of constituents, their structure and function, solubility & extraction, synergy and variability, which plants contain which phytochemicals, how constituents contribute to the actions and energetics of Western herbs, and how to use our knowledge of them in clinical practice and for herbal pharmacy / medicine making.
If you really want to understand constituents and basic botanical chemistry, this could be the class for you: The comprehensive course includes two 12-week sessions, each with videos, study guides, PowerPoint decks, handouts, quizzes, optional assignments, a forum, and weekly live webinars with Lisa Ganora and Kat Martello.
Registration for Herbal Constituents 2 remains open for students & graduates of HC 1.
Comfrey & the PA Puzzle - Short Course
Learn the history of the different Comfrey species & cultivars, their synergistic phenolic constituents & the pyrrolizidine alkaloids (PA): what they are & why they matter.
We'll answer the many questions herbalists have about Comfrey: Is it safe? What about leaf vs. root? Is one species safer than another? 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 damage? How much is too much? How valid are the case reports and contraindications? How can we interpret them in the context of clinical herbalism? What's the latest science?
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!
