I had a bad kidney infection, I went antibiotics. My ND suggested charcoal poultice over my kidneys to help with inflammation and told me to keep the poultice pretty wet. I made a charcoal poutice into thick paste put on my kidneys and put plastic wrap over it and bandaged in place and put two towels down on my bed and went to sleep the next day the inflammation was gone, but I continued doing this for few hours a day for two weeks.
I had kidney inflammation, it was kidney infection my MD prescribes antiobiotics for two weeks, sometimes one just must take it. My ND told me to make a thick wet charcoal poultice keep it wet all night and keep in on my kidney to decrease inflammation, I put the charcoal poultice on my skin thick wet and put saran wrap plastic over that and secured it with medical tape. I put a big piece of plastic on my bed and towel over it just in case , put my pajamas on went to bed . In the morning I would just took the plastic wrap off in the shower and gently wash the charcoal off my kidney area this was the easiest, and mess free way. I did this for a few nights.
Kidney pain for me is the worst. When I get this pain I open 4 capsules of activated Charcoal mix it in water drink and within minutes the pain is gone. I've always used this with lemons. If I have blood in my urine I do the juice of 4 lemons, the Charcoal, and drink lots of water.
