In traditional Chinese medicine, there are several ways to treat external injuries.
Herbal medicine is a common approach. Some herbs like Sanqi (Panax notoginseng) have hemostatic and anti - inflammatory effects. They can be ground into powder and applied to the wound to stop bleeding and reduce swelling.
Acupuncture and moxibustion can also play a role. Acupuncture around the affected area can help relieve pain and promote qi and blood circulation. Moxibustion uses the heat of burning mugwort to warm the injured part, which is beneficial for promoting blood circulation and reducing muscle spasms.
Tuina (massage) is another way. Gentle massage near the injury can relieve muscle tension and improve local blood flow, which is helpful for the recovery of the damaged tissues. However, for severe external injuries, it's often necessary to combine traditional Chinese medicine methods with modern medical treatment.
