Few factors are as important to health maintenance and disease resolution as is good nutrition.

A holistic approach to health will always involve nutritional interventions.

In this course, we'll address foundational, universal principles of nutrition which can apply to any diet type, while identifying particular diet adjustments that can help with common troubles. 

We'll also look at herbs as nutritive in their own right - as providers of mineral, vitamin, and phytonutrient compounds that can bolster a diet that's otherwise lacking.


You'll learn:

  • what does "healthy diet" mean, and why is it different for different people
  • practical ways to eat healthy in a world filled with processed foods
  • how food impacts our health, especially in terms of systemic inflammation
  • how to make sustainable changes to your eating habits
  • how to handle food allergies and sensitivities without going bananas


And especially: 

  • how can we blend dietary changes and herbalism to help a person become more resilient and vibrant?


This course includes 18+ hours of video instruction, 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.

Nourishment is healing.

It's not easy to change how we eat, but the rewards can be great. Understanding how to begin and what to focus on will simplify the problem and clarify your path forward.

I thought this course would be mostly review, but there was so much new information and so many different ways of looking at things. Katja and Ryn's down-to-earth, empowerment-focused approach was a breath of fresh air. Thank you both for creating this awesome, very informative course! I can't wait to take other courses from Commonwealth!

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.
