Unlike some natural remedies which are later proven to be right based thousands of years of use in ancient times, Homeopathy is completely and totally bogus. It's based on absolutely nothing. Not science, not observation, not tradition. It's based entirely on one guy, who, in ~1800, thought that 'like cures like'. So, if you have a fever, why not take something else that causes you to get hot? It's also based on the idea that water has a memory of things it comes in contact with. So, they dilute it thousands and thousands of times until the water or sugar pill has no molecules at all of the thing that is supposed to be treating you. In the end, it's a sugar pill that has a placebo effect on some people. There's no logic, science, or medicine to it at all.
Pro tip: If water really did have a memory and diluting things made them stronger, then all water everywhere would cure everything. Including terrorism since Bin Laden was buried at sea.
I don't disagree with that, I disagree with how the article was written, I am not defending homeopathy, I am among other things criticizing for example the conflating of the issues you mentioned with manufacturing issues that also happen with normal medicine.
