Course Description

Guìzhī 桂枝 Formula Family

A Clinical Masterclass for Pattern-Based Practice

In this 4-hour intensive, you’ll develop real clinical confidence using the Guìzhī 桂枝 formula family—some of the most versatile and frequently prescribed formulas in classical medicine.

Rather than treating Guìzhī formulas as “exterior-relieving” one-offs, you’ll learn how to recognize the deeper constitutional patterns they address and apply them precisely in modern clinical settings.


What you will learn

By the end of this class, you will be able to:

  • Identify constitutional types that respond best to Guìzhī-based formulas

  • Recognize hallmark tongue, pulse, and abdominal findings

  • Differentiate similar clinical presentations with precision

  • Understand when to modify formulas and how to do so safely

  • Avoid common prescribing errors

  • Apply these formulas confidently across a wide range of conditions

“Eran is an exceptional teacher - passionate and enthusiastic yet clear and relaxed. You can tell he has truly embodied the knowledge and devoted himself to learning and teaching the formula families. Hearing about his clinical experience in China and Canada is invaluable. The way he presents the information through his slides and clinical cases allows you to feel ready to implement it into your clinical practice immediately. Learning the formulas through families and constitutions makes studying classical formulas make so much more sense. Eran is a treasure and his classes are game changers! Thank you, Eran!”

Kylie Rodger

“Eran is amazing at transmitting knowledge through his teaching style and the material he put together. He made sense of so many questions I had from the few years I've been studying the Shang Han Lun and Jin Gui Yao Lue - and I didn't even have to ask the questions! He explains everything in great detail and a way that makes sense. The formula family model of herbal application makes sense out of the vast and wide world of Chinese herbal medicine and I cannot wait for the Ma Huang family course! Thank you very much Eran, I look forward to the next class!”

Bob Malecki

“We can’t all leave our lives to go apprentice and study for extended periods with renown scholars in China, but we can all study with Eran Even! I highly recommend his formula family classes as described by Dr. Huang. Through the jumping off point of constitutional body types, you are taken through a deeper study of how to differentiate related formulas informed by Eran Even’s clinical experience. ”
