Liver masters the tendons means that under the nourishment of liver blood, the tendons, bones and joints can move freely and be strong. The basic theory of Chinese medicine is that the liver is the tendon in the body, and the tendons are the important tissues connecting the muscles and joints.

If the liver blood is insufficient and cannot nourish the fascia, there will be numbness in the joints of the limbs, difficulty in flexion and extension, and even tremors and convulsions. And if heat and evil congestion, robbing the liver yin, also have fascia loss of nourishment, appear limb twitching, horn bowing, neck straightening and other symptoms. Clinically, if there is deficiency of liver blood, loss of nourishment of sinews, and numbness of limbs, it can be treated with Astragalus, Gui Zhi, Wu Wu Wu Tang. The composition is astragalus, cinnamon sticks, white peony, jujube and ginger. It is indicated for blood paralysis. Adverse reactions and contraindications are not clear. If there is any discomfort, consult the hospital in time and treat under the guidance of professional physicians to avoid delay.
