When my ds was 16 mos, he developed head-to-toe eczema. It was horrible, itchy, hot, red, the stuff of nightmares. For a year, I tried everything. Allopathic creams/lotions/liquids/pills, herbal lotions/tinctures, homeopathics, elimination diets, NAET. Then, when he was 28 mos, I tried a homeopathic I found on the internet. The eczema began to clear within 24 hrs and was completely gone within a week. For the next 1.5 yrs, I stopped giving it to him for a few days every 3-4 months. The eczema would come back. Finally, it didn't come back when he stopped taking it.
He was way too young for it to have been a placebo. He had no way to tell the thing that worked from all the other things we had tried. I know it is hard to find the right homeopathic remedy, as we had tried others before the one that worked. But, when you do find the right one, it does work.
