Hawthorn is not used clinically to treat frostbite. Hawthorn is a commonly used herb in clinical practice, but it is used to treat patients with weak spleen and stomach and poor digestion. This is because hawthorn can help eliminate food and strengthen the spleen and stomach, but it is not used to treat frostbite. Frostbite occurs when the patient has been in a cold, humid environment for a long time, and there are problems with local blood circulation that cause frostbite. Therefore, in the treatment of frostbite, it is recommended that the patient must strengthen warmth, and also must insist on physical exercise and local massage. This can increase the local blood circulation and prevent frostbite. In the treatment of frostbite, patients are advised to apply ointments such as frostbite ointment and oral vasodilators.
