Strengthen Sinew Pill (Bu Jin Wan) nourishes and invigorates the liver and kidney in order to strengthen the sinews and bones. It is effective for treating chronically loose joints, whether due to constitutional insufficiency, or in cases following injury in which sinew healing is delayed or slowed. Strengthen Sinew Pill can also be used for chronic and habitual dislocations due to impairment of the liver and kidney’s ability to nourish the sinews.
