So basically, if I understand correctly, homeopathic philosophy includes the notion that if you - as a completely whacky example - vomit excessively because you've swallowed ipecac that you'll be "immuner" to the vomiting caused by the flu?
Basically, yes. Not only this, but it claims you can stop vomiting by drinking magic water that contains the magic essence of ipecac. These are the sorts of people who used mercury to "treat" silver liver syndrome (but to be fair, "how could something as awesome as mercury NOT be good for you?")
So it's partly a hokey form of immunisation that ignores "wasp venom does not immunise you against wasp venom, it just builds up and makes the next ting more likely to kill you or cause an allergic reaction", partly a mind-numbing idea of "all things that cause X are the same, so immunity to one of them is immunity to X" and partly using the cause of a syndrome, in tiny amounts in water, as a form of antivenin.
And it doesn't work like that.
And I think what Frank meant was that "an immunisation introduces a small, hopefully controlled amount of the disease - in some cases even "deactivated". The body quickly learns how to fight it, and makes lots of antibodies. When the real thing comes along, the antibodies kick the crap out of it and steal its possessions. In a sack.
When you put a small amount of a toxin into water, it sits there. It... just sits there. The water doesn't adapt to it or produce things to combat it, so when you then drink it, you're just drinking the water and also the toxin."
Note that if it were a bacteria, then sure, it would probably grow and infect the water (or it would drown and die off, or something else there would interact with it, perhaps), so when you drink that, either you took a risky immunisation or you just infected yourself properly. But homeopathy deals with poisons (mainly "poisons that make you stay awake/excessively tired/have a headache" as opposed to "cyanide, carbon monoxide, arsenic and titanium"). Poisons aren't alive, they just sit there and wait for you to swallow them.
