Eucommia Bark
One of China's most prized tonic barks — Eucommia Bark tonifies Liver and Kidney Yang, strengthens bones and sinews, calms the fetus, and supports healthy blood pressure with its warm, deeply nourishing power.
What Is Eucommia Bark?
Eucommia Bark (Du Zhong, 杜仲) is the dried inner bark of Eucommia ulmoides — China's only native deciduous rubber tree — and one of the most celebrated tonic herbs in Traditional Chinese Medicine. Characterised by the fine white latex threads visible when the bark is broken, Eucommia has been prized as a premier Yang tonic and musculoskeletal strengthener for over 2,000 years.
Sweet and warm in nature, Eucommia Bark enters the Liver and Kidney channels. Its primary actions are to tonify Liver and Kidney Yang and strengthen the bones, sinews, and lower back. In TCM theory, the Kidney governs bone and the Liver governs sinew — and Eucommia's dual action on both organs makes it uniquely effective for the musculoskeletal system. It is also one of the foremost herbs for calming the fetus and preventing miscarriage in patterns of Kidney deficiency.
History & Origin
Eucommia Bark has been documented in Chinese medicine for over 2,000 years, holding a consistently prominent position in classical materia medica as one of the most valued and effective tonic barks.
