Frostbite occurs when the skin of a person's extremities (usually hands, feet and nose) has been exposed to cold temperatures for too long. If the skin is cold, pale or numb, there may be frostbite. The extent of frostbite varies greatly, depending on the length of time a person has been exposed to the cold...the intensity of the cold, humidity and winds.. .the kinds and amount of clothing worn...a person's natural resistance to cold...as well as a his/her general state of health.

Home remedies for frostbite
Steep a teaspoon of sage in a cup of hot water for five minutes and drink it. Sage tea will help improve circulation. When we were kids, we saw a cartoon of a male Eskimo urinating ice cubes. Funny? Yes. Accurate? No. No matter how cold we are, our urine stays fairly warm. If you're indoors and without warm water, apply urine to your frostbitten areas. It should help you thaw out.

Soak mullein flowers in olive oil for fifteen minutes and apply to frostbitten area. Pour witch hazel over the frostbitten areas. Warm some olive oil and gently dab it on the frostbitten skin or apply it with a kitchen pastry brush. If you have an aloe vera plant or bottled aloe vera gel, gently apply it to the frostbitten area.

Cover the frostbitten area with the inner side of a banana peel. Boil and mash potatoes. Add salt and apply the mixture to the frostbitten areas. If you're hungry, eat the potatoes and apply the warm water (in which the potatoes were boiled) to the frostbitten areas. Use cold water to soak frostbitten areas. If the hands are frostbitten, rub them but do not hold directly to heat.
