If you listen to that ad it states that it is a 'homeopathic' remedy. Homeopathy has nothing in it. It's water, colors, flavors [sometimes], and 100% placebo. And as such, it helps in about 25-30% of the cases tried because that is the same rate as doing nothing. It does -steam- me to hear that and similar ads.

But that may be bitterness on my part. I can't fool myself with placebo.
