Practice herbalism safely.

A thorough understanding of Herb-Drug interactions and Herb Safety is critical if you plan to practice as a clinical herbalist.

But these days, it's just as important for folks practicing at the Community level too: so many people take pharmaceuticals today! 

That's just not something that herbalists had to deal with even just a couple decades ago.

Take the time now to get in-depth and detailed about the potential for herb-drug interactions, and about all the considerations for herb safety, so that you know you're serving your community and your clients well!

In this course, you'll learn how to:

🌿 Practice safely even when you don't have all the information you need

🌿 Identify and assess herb-drug interactions, read studies and case reports, and determine how they're applicable to your practice

🌿 Understand the mechanisms of actions of plants and pharmaceuticals so that you can make accurate assessments about where there is risk

🌿 Understand the herbal constituents that are most likely to cause interactions or safety concerns, and what to do to work around them

🌿  Make adjustments for people who have special risk factors, like elders or people with complex medical issues

And you'll learn all about the known interactions and known herb safety issues to date!


This course is currently being updated and new material is being added so that you're up-to-date with the latest details! 

You'll get 25+ hours of instructional videos, as well as PDF handouts, quizzes and homework assignments, and more - plus weekly Q&A discussions where you can talk directly with Ryn and Katja.

Your Teachers

Two heads are better than one!


Katja & Ryn
Katja & Ryn

Katja & Ryn almost always teach together. They each have particular talents and areas of interest, and their perspectives on certain issues are quite different! Together, they convey a fuller picture of the realities of herbal theory & practice than either one could do alone.

Katja is an herbalist and teacher working to help people rebuild their relationships with their bodies and their own ability to heal. She’s been in practice for nearly 25 years, but it all began with a desire to make her own “fancy tea” at home instead of paying high prices for imported blends at specialty stores. She’s kept that do-it-yourself ethic close to her heart.

Ryn has been a practicing herbalist since 2010. He came to herbalism by way of martial arts, where his first experiences with herbs were focused on getting back into the game and becoming more flexible, adaptable, and resilient. Passing that experience on to others is what keeps him motivated every day.

Together, Katja and Ryn teach everyone from children to elders, as well as pharmacy students from Massachusetts College of Pharmacy and Northeastern University School of Pharmacy, where they both serve as associate faculty. Ryn and Katja are the authors of Herbal Medicine for Beginners, and the creators of the weekly Holistic Herbalism Podcast.
