Materia Medica is the way herbalists refer to their “dictionary” or “tool box” of plants. It is, literally, the “medicinal materials” – herbal allies ready to assist in times of need! 

The most important part of herbalism is the plants themselves! Get in-depth with more than 89 of the most versatile and prominent plants in contemporary herbalism. 

Ryn Midura and Katja Swift make learning herbalism as easy as watching TV!

This program includes videos about each plant as well as PDF handouts, introducing you to each plant as if they were a new friend (they are!). You'll learn all the ways that we work with each herb and how it can help you. You'll learn when it's appropriate to work with each herb, and if there are any contraindications. Detailed, up-close photographs will help you learn to identify that plant in the wild.

This course typically takes 8 weeks to complete, but you can watch the videos at your own pace, and re-watch them at any time.

Feel confident with a whole toolbox full of herbs that you can turn to when you need them!

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 20 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.

I am no spring chicken :) As such, deciding to study herbalism at a later stage in my life was something that, although I knew was the path for me, I was highly skeptical of. I looked through so many schools and various courses and each one sounded great! Then I came across Ryn and Katja. As soon as I watched the first introduction video, something clicked. I saved up and bought this first module, the Materia Medica. I have loved every minute of every video. I am so pleased with the way they both teach and I simply cannot sing enough praises for the two of them. Their vast knowledge and true passion for what they do is evident in this course. I cannot wait to venture further in my own studies.

I learned so much in this module. I'm so glad I decided to take it as a part of the herbalism 101 bundle. Katja and Ryn make learning extremely accessible and I appreciate how sensitive they are to environmental, social and economic injustices when talking about herbalism. I'm looking forward to the medicine making portion of the bundle and feel like this gave me a really good foundation. I highly recommend it!

The Holistic Herbalism Materia Medica Course was awesome! Sooooo many plants, I found I would learn about a plant then walk outside my front door and see it growing. Ryn and Katja made the content enjoyable and easy to understand and really fueled a desire and got me stoked to know and understand the plants more. I am looking forward to taking the Community Herbalist Program soon. Grace Bisaro

I joined this class after listening to the free podcast for a few months. Katja and Ryn's approach to Herbalism is fun, practical, and unique. As an individual who has trouble with traditional approaches to learning, the Materia Medica class was refreshing, easy to follow and challenging at the same time. What I learned here helps with my aromatherapy classes and vice versa.

I absolutely adored this course. The combination of video, audio file, text and short quiz for each herb is such a brilliant idea and for me was just the perfect match for my learning style. Katja and Ryn are so full of joy and excitement on top of their vast knowledge, that you can't help but feel inspired right along with them. I love learning with them so much and will keep learning with them until I run out of courses to take ;)

I finished Materia Medica, yay! When you first look at the list of herbs covered, it can be overwhelming. And, when you've gotten through the first few, you still might feel like there is NO way you will be able to retain (or understand) any of this information. But, somewhere along in the process, you start to GET IT. You might really notice this when taking a quiz - you read a question and think, 'hey - I don't remember them specifically covering this in the video(!?!)' But then...magic happens (or critical thinking, but it feels like magic) and you start to put the pieces together on your own, 'well if this herb has astringent properties than the correct answer to this question would be..." Magic! Honestly, the teaching style, the presentation, the explanation of how the herbs work in our bodies (and just how our bodies work in general), and their truly congenial personalities, make Katja and Ryn the herbal dynamic duo! You should really take this course.

The Materia Medica course really changed how I was learning about herbs. By the end of the course, I was seeing so many connections between the herbs and how to use them. I absolutely loved this course --the instruction was top notch. I rarely had questions because each module was so thorough. Katja and Ryn are so generous with their knowledge and I have enjoyed all aspects of their teaching . I've already signed up for two more courses and I can't wait to start my next course !
