Your immune system is working 24/7 - even when you're not sick!

Even if it's not flu season, your immune system is constantly protecting you from pathogens in your environment - which means you've got to keep it running smoothly.

And for many of us, that constant vigilance gets out of hand and turns into problematic inflammation and autoimmunity.

Together, let's get your immune system into that "goldilocks" place - ready to protect you when you need it, calm and cool when you don't.

In this course, you'll learn how to:

  • keep your immune system at peak performance so you stay healthy
  • understand how inflammation works, and how to support the healthy version of inflammation
  • reign in inflammation that's run amok
  • rebuild your immune function after an illness
  • calm down immune function that's gone overboard in autoimmune conditions

The course includes 30 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.

The best immune system is the one that's "juuuust right"

Herbs and holistic strategies can get you there!

Teach Me How!

What you'll learn

  • How the Immune System works

    When you understand what's supposed to happen and how to support it, it's easier to get yourself to that "Goldilocks" healthy balanced place!

  • Which herbs best support immune health

    When is Echinacea appropriate? Are there any times that you shouldn't stimulate immune function? What herbs are safe when you've got an autoimmune condition? You'll be confident on these and many more!

  • Build healthy, strong balance!

    Whether you're the one who always gets whatever's going around, or you're trying to cope with an overactive immune state - you'll learn what you need to know to come to a place of balance.

For the first time, I am almost through the winter and I haven't been sick - even though everyone at work has been. I feel like I'm finally learning how to work WITH my body!

Vanessa P.

"I researched different online herbalism courses for about two months and am so glad I found you two. There is so much more than just the material to this course.

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.

Zero-Risk Return Policy

Teaching isn't just about conveying information - there's also an aspect of being someone's "cup of tea".

So we want you to take the first 14 days to really decide if you love it or not. If for any reason you feel like this program isn’t right for you - if we're just not your cup of tea - we’ll give you a full refund. You don't even need a reason - just please let us know within 14 days of purchase.
