Achyranthes Root (Niu Xi): A Circulation-Moving Herb for Joints, Blood Stasis, and Lower Body Health
Introduction
Achyranthes root, known as Niu Xi (牛膝) in Traditional Chinese Medicine (TCM), is a strong and flexible herb prized for its ability to invigorate blood, strengthen the tendons and bones, and guide qi and blood downward. With its bitter, sour, and neutral nature, Niu Xi is often used to treat joint pain, menstrual irregularities, blood stasis, and issues affecting the lower back, knees, and urinary tract. Whether used in classic trauma formulas or modern support blends, this versatile root provides targeted support for circulation and movement.
What Is Achyranthes Root?
Niu Xi refers to the root of Achyranthes bidentata, a hardy herbaceous plant native to China. In TCM, it is classified as bitter, sour, and neutral, entering the Liver and Kidney meridians. Traditionally, Achyranthes root is used to invigorate blood, dispel blood stasis, strengthen the lower body, and promote the downward movement of blood and fire. It is especially favored for treating conditions that involve weakness, stiffness, or blockages in the joints and lower extremities.
Health Benefits of Achyranthes Root
Invigorates Blood and Dispels Stasis
Niu Xi is used for blood stasis symptoms such as menstrual irregularities, amenorrhea, or trauma-related pain and swelling.
Strengthens Tendons and Bones
It is beneficial for weakness, soreness, or pain in the lower back, knees, or legs, especially in aging or post-injury recovery.
Promotes Downward Movement of Qi and Blood
Achyranthes helps redirect rebellious qi or blood downward, useful in headaches, dizziness, or hypertension caused by ascending Liver yang.
Clears Damp-Heat from the Lower Jiao
Niu Xi aids in treating urinary difficulty, painful urination, or swelling due to damp-heat in the lower body.
Assists in Labor and Promotes Menstruation
It is sometimes used under supervision to encourage labor or stimulate delayed menstruation by moving blood strongly.
