External application of Chinese herbal medicine after a fracture can be done with the main formula of Tao Hong Si Wu Tang, adding Chuan Wu and Chuan Xiong to invigorate blood and relieve pain. However, it is not recommended to use Chinese herbal medicine in the early stage of fracture, because it may aggravate the bleeding and increase the swelling, thus affecting the position of the fracture and the pain. It is recommended to apply topical Chinese medicine 2 weeks after the fracture, because new bleeding is unlikely to occur at this time, and topical Chinese medicine can accelerate local blood circulation and reduce swelling to promote fracture healing. In addition to the external application of Chinese medicine, you can also take oral Chinese medicine to invigorate blood circulation and remove blood stasis, which can quickly reduce swelling.
