The kidneys are a lot more active than you might think!

They're more than mere "filters" for the blood; they work proactively to maintain the mineral and chemical balance of your blood, and to keep your fluids moving and circulating.

Learning to take good care of them, as well as the bladder and urinary vessels, goes far beyond "herbs for UTI" - though that's a good place to start! We'll take you through the whole system so that you can keep everything running right.


The course includes 10 hours of video instruction, as well as PDF quick guides, quizzes and homework assignments, and integrated discussions where you can talk directly with Ryn and Katja.

The best herb school online!

"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. Because you teach everything in videos, and then with the live Q&A sessions every week, I feel like this is more of an in-person experience than an online course and I love that."

Don't hold it.

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 also 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.
