Huh. Well, we do inject people with weakened diseases (vaccines). So in that example, "like" really does cure "like", by training our immune system.
So, uhh, that part is kind of true. Only when it's not diluted so many times that it ends up being pure water.
A cutting edge treatment for nut allergies is to consume small amounts of nuts (carefully prepared, etc.).
edit: I want to differentiate the nut thing from homeopathy. The idea there is to consume a very small and carefully measured portion of the nut, not some nonsense about training molecules.
It makes total sense for nut allergy where the disease is the intolerance; if you become immune to the substance you are cured.
Toothache is not an intolerance to deadly nightshades and no level of resistance to the poison will cure what is a totally unrelated issue; pain caused by a something slowly digging a hole through my gum.
It looks like both homeopathy and the vaccine were even introduced in the same year(1796), which was a spooky coincidence when I looked it up just now.
Not even close to the same thing.
I guess that their downfall in this case was that the manufacturer was a True Believer who actually bothered with the whole add poison to water then water it down until poison is gone, rather than, y'know, just packaging tap water.
The snake oil might be completely ineffective, but it better at least be oil from an actual snake.
Wait, where do you think the vast majority of bottled waters come from? Actual springs?
Is it good to make pancakes?
