The Asian culture seems to go for this more esoteric approach, which explains a lot of ADA stuff. I love ADA, don't get me wrong, but some of the products are pretty out there. Penac, Tourmaline BC, etc.
Well, such questions are better suited to a cultural scientists rather than a plant scientist.
However, perhaps Germans are similar with heating cables?
That's pretty far out there as well.
USA? Haha, Hydrilla pills to increase virility, stamina, longer life, weigh loss etc, 30$ for a 30 day supply.
I think each culture is suckered well by these hucksters.
