“Absolutely Terrific!

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

“Wow! Clear and concise. Clinically relevant.

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

“In depth and practical

Eran's understanding of herbal medicine is beyond anything I've experienced in my 20 years in this field. He eloquently synthesizes history, function, and clinical relevance. You can tell he's spent years not just studying but sitting with Chinese Medical concepts. He is embodied in his understanding. This class was incredibly useful and took us beyond the standard way most of us are used to thinking about Gui Zhi as strictly being an exterior herb. When he teaches about Gui Zhi from a flavor perspective, it just makes so much more sense! I left with a better understanding of the formulas, how and when to use them, and what type of constitution to look out for. If you are serious about herbs (beginner or advanced) you will not regret taking this class.” Paula Woodward
