Eucommia bark (Du-zhong) – The Herb Used in Traditional Systems to Support Normal Kidney Function and Bone StrengthEucommia bark (Du-zhong), also known as "Eucommia Bark" or "Gutta-percha Tree Bark," is the traditional Chinese name for the dried inner bark of Eucommia ulmoides, a warm, slightly sweet herb from the Eucommia family that has been part of traditional Chinese herbal systems for over 2000 years. This warm, tonifying herb is particularly known for its ability to support normal kidney function, promote normal bone strength, maintain normal tendon and ligament health, regulate normal blood pressure and restore normal vitality – making it an ideal choice for people with a tendency toward normal lower back discomfort, normal knee weakness, normal leg fatigue, normal bone health support and normal age-related strength loss.Traditional Understanding in TCM SystemsWithin traditional Chinese medicine, eucommia bark (Du-zhong) is described as a warm, slightly sweet herb with tonifying and strengthening character. In the TCM theoretical framework, it acts on the so‑called Kidney and Liver meridians. According to this traditional description, eucommia bark (Du-zhong) primarily supports normal "Kidney Yang tonification," helps "normal bone strengthening," "normal liver-strength support" and "normal blood pressure regulation" – crucial TCM concepts for normal structural integrity and normal vitality.Eucommia bark (Du-zhong) is seen in TCM as a classical "Kidney Yang tonifier and strength enhancer" – one of the most prized tonifiers for normal lower body strength. It is traditionally used to promote normal kidney function support, strengthen normal bone structures, support normal liver health, regulate normal blood pressure and promote normal long-term vitality.Special Property: Warm and Tonifying with Strength-Enhancing ActionEucommia bark (Du-zhong) distinguishes itself by its very warm, tonifying character and strong "strength-enhancing" effect without vigorous stimulation.
