This tree bark is used as a Yang Jing, or male energy, tonic in Traditional Chinese Medicine. Its sap contains natural latex, making rubbery strings between bark sections. These strong but elastic strings show the signature of Eucommia’s use to strengthen the back, especially lower, and skeleton and joints, especially the knees and ankles.
Eucommia is also believed to give greater strength and flexibility to the ligaments and tendons, and so is popular among athletes. It has also been found to regulate blood pressure, especially in cases of high blood pressure. Finally, it is considered a safe sexual tonic for men and women, and is used widely as a longevity tonic.
Note: Eucommia may cause reactions in people allergic or sensitive to latex.
