Ginger can play a role in promoting the recovery of frostbite. However, when applying it, patients need to be careful because some patients with frostbite, already have localized blisters or even skin breakouts occurring. If ginger is repeatedly applied at this time, it may break the existing blisters and may even form new irritation on the surface of the existing ulcers, so that the patient may experience severe pain. Therefore, applying ginger to frostbite is recommended to be done before the frostbite has formed blisters, and not when blisters are formed. Because ginger itself has certain pungent properties, it is not recommended that patients repeatedly come to do this, although applying it to the skin surface can have a certain effect on improving blood circulation. This is because repeatedly doing so may also cause some damage to the surrounding normal skin tissue.
