1) Warm Fluids Frostbite Treatment
Try to give the individual warm fluids to drink.  This will not only warm their core body temperature, but warm liquids can be soothing and can help to treat the frostbite.  It is important that you do not serve them any fluids with caffeine or alcohol.  These substances can inhibit blood flow and can actually make the frostbite worse.  This is a useful frostbite home remedy.

Use a sterile, dry bandage and apply it to the affected area.  If the frostbitten body parts are fingers or toes, separate each digit with cotton.  This will help to prevent rubbing or chafing of the body parts.  Once the wounds are properly dressed, seek medical attention from a healthcare provider as soon as possible.

Frostbite

If there is a chance that the affected body part may become frozen again, do not warm or thaw the frostbitten body part.  This is an ineffective treatment and can actually cause more harm than good.  If a thaw-refreeze cycle is begun, the results will be far worse than the original effects of the initial frost bite.

Try to avoid gradually thawing the frostbitten body part.  It is best to re-warm the area quickly and thoroughly.  If you are not in an area where this is possible, wait to try to re-warm the body part until you are in an area where you can properly warm and treat the frostbitten body part.

Do not allow any friction on the frostbitten area.  While some may advise rubbing snow on the affected area, this is actually one of the worst things you can do for frostbite.  The friction that is caused by rubbing the frostbitten area will cause the body's tissues to be further damaged.

One of the best treatments for frostbite is immediate transport to a facility that can properly warm and treat the affected areas.  The severity and longevity of the injury is directly related to how long the body part was frozen, not by the actual temperature to which the tissue was exposed.  This is why it is so important to recognize the signs of frostbite and begin to immediately transport the victim to a proper treatment facility immediately.

2) Quick Thaw Frostbite Treatment
Thawing the frostbitten tissue is one of the best and most effective treatments for the injury.  This cannot be a gradual thaw, rather, it must be done quickly and the best way to accomplish this is by thawing the area in a bathtub.  Do not try to sit by a warm campfire, stove or oven to thaw out the frostbitten skin.  A soak in a warm bath is the best way to thaw frostbitten skin.  The water temperature should be approximately ten degrees (Fahrenheit) warmer than the normal body temperature, so the bath water should be about 102 to 111 degrees.  The dry heat of a fire or stove will only burn the frostbitten tissue.  This is because nerve endings in frostbitten tissue are unable to signal the brain to tell you that you're in danger of burning yourself.
 
Anything metal should be avoided.  This includes metal machine controls and steel toe boots.  Even if you are otherwise prepared, coming in contact with cold metal can quickly cause tissue to become frost bitten.  If you must handle cold metal in weather conditions that can contribute to frostbite, be sure to take every necessary precaution, including protective clothing like warm wool socks, gloves and mittens.
