The earthworm, also known as tuyuan, has the effect of activating blood circulation, relieving swelling and pain, and also has a certain effect on calcium metabolism, which is effective in promoting fracture healing and relieving swelling and pain for patients in the early stage of fracture. It is recommended to grind it into powder and take it with warm water, about 6g each time, once every three days. It is also important to eat foods with high calcium content, such as milk, soy products and eggs, and foods rich in vitamin D, such as animal liver. In the early stage of fracture, you can also take Chinese medicine to activate blood circulation, relieve swelling and pain, and promote bone metabolism, such as compound wound pain and wound jointing tablets.
