Chuan Niu xi, also known as Ox Knee, is a plant with white flowers native to China. TCM has been using the benefits of its roots on the joints since the dawn of time.

By stimulating blood circulation, Ox Knee effectively soothes joint sensitivity**. This plant acts on the Liver and Kidneys, the systems that "govern" the tendons and bones respectively in TCM, which explains its beneficial action on the skeleton.
