Homeopathy was quackery in 1796, it was quackery in 1988, and it will still be quackery in 2096 – Respectful Insolence:
"Homeopathy, of course, rests on two principles. First, there is the idea that “like cures like,” which states that to relieve a symptom you should use a substance that causes the symptom in healthy people. The second idea behind homeopathy is that dilution makes the remedy stronger."

Now, I want you to read those two principles a few times and tell me if they make any sense from what you know about how the world works. The best case scenario for homeopathy is that it "works" in the same sense as a placebo "works".
And no, the fact that there are "Big Pharma" medications that are also crap does not excuse licensed pharmacies from selling homeopathic remedies. They are, simply put, knowingly defrauding their customers.
