The main drugs used to treat frostbite are oral and topical drugs. Oral drugs can use vitamin B3, which has a vasodilating effect, and topical drugs can use vitamin E cream, frostbite cream, heparin sodium cream, etc., which have antioxidants and promote blood circulation. General frostbite topical medications can achieve the desired effect. For frostbite patients on the basis of medication, more should be done for daily protection, paying attention to warmth, proper exercise, and improving metabolism. Daily maintenance can also use horse oil. The main component of horse oil is petroleum jelly, which has the effect of moisturizing the skin and relieving chapping, but horse oil can only play a certain therapeutic effect and is not the best topical preparation for frostbite, mainly using vitamin E cream, sodium heparin cream, etc.
