The use of herbs for external application after a fracture is useful because it is one of the more effective methods of treating fractures in Chinese medicine. If the fracture is in the early stage, the principle of treatment is usually to activate blood circulation and eliminate blood stasis, reduce swelling and pain, so the early stage can be given to use safflower, peach kernel, red peony, angelica, chuanxiong, or haitong bark, frankincense, myrrh and other Chinese herbs ground into powder and then give external application, which can promote the swelling and pain after the fracture to subside. In the middle and late stages of the fracture, herbs that strengthen the tendons and bones, nourish the liver and kidneys, and dispel wind and dampness can be applied externally, for example, using medicines such as sequestra, eucommia, hyssop, mulberry and jackfruit.
