I had crazy periods too and would get hormonal Acne with the bumps and stuff.. DE (1 leveled kitchen spoon full in a glass of juice) once a day cleared my skin up within a week. If you have constipation, that wrecks your skin too... but the DE worked the best. I've probably read a million things about what it supposedly cures... but all I can attest to is that it really does pull toxins out of your gut.. even if you only take it once or twice a week (followed by yogurt at least 4 hours after taking it because it will pull out good bacteria too- (i learned that the hard way!)
I'm happy to hear that Iodine has helped... i just had a uterine ablation yesterday... i probably could have reversed it with iodine, but i have a clean slate now to start over.
