Yunnan Baiyao powder sprinkled on a wound can be used to stop bleeding, but the healing time of a wound is related to its location and severity. Yunnan Baiyao has the function of removing blood stasis and swelling, stopping pain and stopping bleeding. When a wound occurs, Yunnan Baiyao powder can be sprinkled on the wound to help stop bleeding and pain and facilitate scabbing. The wound must be strictly cleaned and disinfected after hemostasis, and if the wound is deep and large, a debridement suture must be done. It is usually not recommended that Yunnan Baiyao powder be left on the wound surface for more than 48 hours, as this can lead to an inability to drain secretions and cause infection of the wound. In addition, wound healing time is independent of the medication used and is determined by the location and severity of the wound, e.g., head and facial wounds heal in about 5 days, abdominal wounds in about 7 days, chest and back wounds in 8-9 days, and extremity wounds in about 14 days. In addition, patients should avoid spicy and irritating food before the wound heals, and pay attention to keep the wound clean and dry.
