You're a Nurse, Carla, so you know that your Skin is your 3rd Kidneys and it's also the LARGEST Organ of the Body! YES, you're going through DETOXIFICATION! I have the People with whom I work, drink 3-5 glasses of Activated Charcoal Powder Slurry, so that it'll ADSORB (electrical, NOT mechanical action) the TOXINS, Chemicals Wastes, Drugs, Pollutants, etc. from the Bloodstream through the walls of the Intestines.
Ginger Root Tea/Tincture will REDUCE the BURNING either INTERNALLY or EXTERNALLY.
Either buy and use a Mortar and Pestle like the Pharmacists used to use. Or buy and use one of those Small Electric Coffee Bean Grinders.
Look at ALL of my Web-Pages on Intestinal Formula No. 1.
