Hawthorn is not used clinically to treat frostbite. Hawthorn is a commonly used herb in TCM, but its effects refer to moving qi and strengthening the stomach, eliminating food and dispersing stagnation. Therefore, hawthorn is used in TCM herbal medicine for internal use to treat elimination of food as well as gastrointestinal disorders, whereas frostbite is a localized end-stage skin disease associated with cold. Frostbite occurs when the patient is in a cold and humid environment for a long time, and in some cases because the local peripheral circulation is not very good, which can lead to frostbite. Therefore, in clinical practice, the first principle of frostbite treatment is to strengthen local warmth and physical exercise, which can effectively improve the patient’s tolerance to cold. You can also apply vasodilator drugs such as niacinamide, nifedipine, and dipyridamole, and you can also apply urea capsule vitamin E ointment and frostbite ointment for topical application.
