From powerful causes spring the empiric's gains, Man's love of life, his weakness, and his pains; These first induce him the vile trash to try, Then lend his name, that other men may buy. (Quote by - George Crabbe)
Out, you impostors! Quack salving, cheating mountebanks! your skill Is to make sound men sick, and sick men kill. (Quote by - Philip Massinger)
