That, at least according to Wikipedia [0], is only the case for C/D 12 and higher. It’s pretty clear to anyone, that weak (homeopathy says the higher the dilution, the stronger the effect) tinctures like D2 (so 1 part whatever in 100 parts water) will still be chemically distinct from just water.

My parents use that as explanation why they use it and not the high concentrations (= high dilutions = pure water). Which requires more mental gymnastics than my brain can handle.
