Eucommia Bark Chinese Herb

Eucommia Bark (Du Zhong): A Strengthening Herb for Joints, Back, and Kidney Yang

Introduction

Eucommia bark, known as Du Zhong (杜仲) in Traditional Chinese Medicine (TCM), is a deeply strengthening herb used to tonify the Liver and Kidneys, support the lower back and knees, and calm a restless fetus during pregnancy. With its sweet and slightly spicy nature, Du Zhong is most valued for its role in reinforcing tendons and bones, making it ideal for those with joint pain, weakness, or Kidney yang deficiency. It is commonly included in formulas for longevity, flexibility, and structural support.

What Is Eucommia Bark?

Du Zhong is the dried bark of the Eucommia ulmoides tree, a resilient plant native to China. In TCM, it is classified as sweet, slightly spicy, and warm, entering the Liver and Kidney meridians. Traditionally, Eucommia bark is used to strengthen the sinews and bones, tonify Kidney yang, calm the fetus, and improve mobility in the elderly or those recovering from injury. It is a key ingredient in formulas for back pain, reproductive vitality, and musculoskeletal health.
