Yunnan Baiyao has local swelling and hemostatic properties and can be used for acute knee falls, with attention to local braking of the knee. If there is a significant local contusion, disinfection and prompt hospitalization are necessary to prevent tetanus. If local swelling is evident, local rest and cold compresses are recommended, and the affected limb should be elevated at bedtime to speed up blood flow and promote swelling. Yunnan Baiyao is an ethnic traditional medicine that is effective in reducing bleeding in acute soft tissue contusions.
