Quackery is medical treatment that
is utter bollocks put politely, doesn't work.
 Lies and false hope
It involves giving false hope to incurably sick, or otherwise ignorant patients and charge exorbitant amounts of money for it. Rather a lot of what is dubbed "alternative medicine" is quackery, as is much of the vitamin and herbal supplement business. Implicit in the word is that the quack's nostrum, whatever it may be, is pure snake oil and the quack him/herself is a liar.
Quacks may set up their practices offshore to duck the more stringent laws governing medical practice in the developed world. Hence, some Americans head to Mexico for Laetrile in clinics just over the border, or travel to the Phillipines for a Bio-Energizing Anti-Cancer Zapper Machine.
"Quack" derives from the 17th century word "quacksalver", in turn from the Dutch word kwakzalver (hawker of salve). Both "quack" and "kwak" originate from the Middle Dutch quacken (to brag or boast). Quacksalvers would appear in town markets offering cure-alls in bottles to anyone gullible to part with their money.
