Herbal Constituents & Make Better Medicine

Herbal Constituents (Early Access)
Registration is now open! Class Information Page

We're doing something new this year: opening up Early Access to Herbal Constituents. We've had a number of requests for this, so we decided to go for it and let enthusiastic students register now! Early Access allows you to view and download all the course materials and get a jump start on your studies before the new live webinars begin (Sept 5, 2024 for Semester 1, & Jan 9, 2025, for Semester 2. Each class in the early access version incudes a recorded 2.5-hour webinar with Lisa Ganora and Kat Martello, with full admin and class support via our lively Forum. Also, we're limiting total registrations to 100 each semester to make sure students get individual attention, so we wanted to give you a chance to sign up early.

Herbal Constituents goes in-depth to explore the nature of constituents, 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. 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 both recorded and live webinars. Sign up for one session or both!

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!
