You should not use Yunnan Baiyao for abrasions. The skin of the abrasion has already been broken, so if you use Yunnan Baiyao, it will stimulate the wound and make the patient feel painful and uncomfortable, and in severe cases, the local skin and subcutaneous tissue may be necrotic. Yunnan Baiyao has the ability to relieve blood stasis, swelling and pain, and is used for local swelling and pain caused by sprains. Patients with abrasions who have bleeding wounds need to stop the bleeding in time. The spraying of Yunnan Baiyao not only does not stop the bleeding, but also aggravates the bleeding, so you cannot use Yunnan Baiyao for abrasions. If the abrasion is superficial, the wound should be disinfected with iodophor and then dressed with sterile gauze.
