Walgreens (and CVS) both also sell homeopathic stuff of all kinds, all over.
Even charlatans can sell stuff and make a ton of money. "Can raise money" or "can trick people into buying" (remarkably similar, really) can not in any way be construed as a validation of a product.
Agreed. Just getting on a store shelf doesn't mean you have a good product, it just means that store believes customers will pay for that product.
Like you said, Walgreens, a major pharmacy specializing in real medicine, sells homeopathic crap. They also sell very unhealthy food and alcohol. They also sell cigarettes. Not because they believe the product is good, but because that product makes them money.
