I thought homeopathy was originally about tissue salts, but it seems to be more mystical nowadays.
The basis for homeopathy the assumption “like cures like” for which there is not one shred of proof or evidence. It’s just something that some german Doctor made up. Whether he really beleived it or was just a charlatan I don’t know but either way it’s nonsense. Then you get the to whole dilution thing which to paraphrase Pauli is not even wrong.
As for mr McIllroy, if he honestly thinks it’s helping him then I’ve not got an issue with that I just think he is being a bit silly (then again he plays golf!) If on the other hand he actually takes money and promotes this stuff, then that is a different matter.
It’s liek those silly nose strips …. I see seom of the TdF riders still use them.
They may not work, but at least there is a (semi) plausible mechanism.
