Hot foot bath
A hot foot bath is the immersion of both feet and ankles in hot water for 10-30 minutes and is an excellent way to draw blood from inflamed or congested areas of the body. This form of treatment is recommended for foot and leg cramps, sore throat, cold, flu, nausea, insomnia, and chest or pelvic congestion.
Wrap the upper body in a blanket to avoid chilling. Using a large dishpan or the bathtub, immerse both feet and ankles in warm water. Keep adding hot water until it is as hot as can be tolerated. Place a cool washcloth on the forehead (keep the washcloth cool during entire treatment by wringing it out in cool water). Keep feet in the water for 10-30 minutes depending on tolerance. As the water cools, add more hot water to maintain the hot temperature. After removing the feet from the water, rinse them with cool water and dry them thoroughly.
This treatment is not recommended for patients with peripheral vascular disease (arteriosclerosis, deep vein thrombosis, Buerger’s disease), diabetes or loss of peripheral sensation.

Warming Socks / Wet Socks Treatment aka heating compress
The heating compress is an application of a cold compress to an area that is initially cooled by the water and then warmed by the influx of blood to the area. It is an effective therapy for sore throat, cold, flu, and sinus congestion when it is administered to the throat or feet.
Make sure feet are warm and dry. If necessary, warm feet in warm water before beginning treatment. Wet a pair of white cotton socks in cold water and wring them out well. The socks should be damp but not dripping wet. Place the socks on both feet. Place wool socks (preferably 100% but no less than 80% wool) over the cotton socks and go to bed with enough blankets so that you are warm during the night. In the morning, the socks should be dry. Perform this treatment every night while congestion / illness lasts. This can be used to treat colds, headaches, sore throats, ear infections, and almost any other problem involving congestion or infection in the upper body and head. This form of treatment is not used for conditions irritated by moisture or for very weak individuals.
