It was asked in one of my groups, so I am sharing my answer here:
"Iodine contrast leaves the body in most people within 24-48 hours. In people with kidney issues, it can take two weeks. The iodine is excreted in urine, so plenty of hydration along with herbs that support the kidneys, liver, and lymphatic system. I recently had a CT. I used milk thistle and burdock root. Other good choices would be dandelion root, red clover, nettles, etc. I worked up a good sweat, have been eating plenty of fiber, and have been exercising. You can also treat the symptoms of your reaction (hives/rash-antihistamine herbs like nettle), but you should notify your doctor and let them know you are having a reaction, if you have not done so."
