“ Natural,my ass! The worst poison known to man comes from a tree frog in South America. You cannot imagine how small an amount would be necessary to kill you.and it's natural.Calling something NATURAL is a MEANINGLESS MARKETING PLOY.All right,calm down! Maybe I like alternative medicine because it's been in use for more than six thousand years.After all that time,they have to know what they're doing.You mean the wacky idea that somehow in the distant past people had more scientific wisdom than they do today?That's both crazy and counterintuitive.Six thousand years ago people thought thunder was a bunch of gods moving around furniture.-Conversation btw Dr.Jack Stapleton and Vinnie ”
