2. It should be noted that Yunnan Baiyao powder should not be directly sprinkled on the wound to stop bleeding. In daily life, many people often apply Yunnan Baiyao powder to the wound to stop bleeding when they encounter traumatic bleeding. As everyone knows, such treatment often leads to wound infection.
3. When smeared on the lesion, attention should be paid to prevent the drug from drying for those with intact skin; If the skin is damaged, it must be thoroughly debrided and disinfected first, and then smeared according to the wound surface after removing foreign bodies.
4. The correct method for external use of Yunnan Baiyao powder should be applied before redness, swelling, sores and toxic pus are broken, and once it is broken, it can't be used for external use.
5. The hemostatic effect of Yunnan Baiyao powder must be achieved through a series of complex physiological processes in vivo after oral administration, rather than simply acting directly on wound blood vessels through its powder. Besides, Yunnan Baiyao powder is not specially treated like special hemostatic powder.
