FWIW, Leeches are now a widely accepted medical tool as are maggots
Right, but I didn't bring those up because they actually have physical effect on our body...water is an inert substance. Leeches are great for thinning blood, maggots are incredibly effective and precise at removing dead flesh.
Treplaning - well we know that pressure on the brain kills brain cells. Primitive technique but they were doing it for the right reasons.
I think originally this was done to "let the evil spirits out" wasn't it? I may be wrong on that one. But, yeah, in a very few cases, they actually were doing the right thing because the reason the person was "acting possessed" was increased pressure on the brain.
Well, I have a graduate degree in chemistry and went to a seminar where an improved response was seen at an incredibly low dilution of a drug
But, was the drug still there, in a mathematical sense? Homeopathic dilutions generally surpass Avogadro's limit (in this specific sense, a ratio of water to active substance beyond which no amount of the original active substance is capable of existing).
And beyond that, it was an actual drug, intended to target a specific ailment - some of these homeopathic remedies use things like red onion to treat hay fever. Now, at least in that specific sense, the two forces acting to make your eyes run are 100% different...that doesn't even follow the whole "like cures like" mantra. I don't know if there's maybe an anti-inflammatory in onion, perhaps, but in that case I'd be wanting to eat an onion...not drink a vial of water that used to have a tiny bit of onion in it =/.
