Homeopathy is thoroughly discredited (seeTrick or Treatment? : Alternative Medicine on Trial,Bad Science,Voodoo Science: The Road from Foolishness to Fraudand other sources).It is particularly concerning to see it sold for use on children. There are documented cases where children have suffered long term harm and some parents have even been jailed for causing the deaths of children through relying on homeopathy instead of medicine.There is no reason to suppose this product should work, no credible means by which it can work, and no good evidence it does work beyond the placebo (i.e. fake treatment) effect. It works the same as a fake treatment for the simple and obvious reason that it is a fake treatment.
