Until about the early 1950's, Coca Cola contained peragoric which I believe is a derivative of the Coca plant which of course is one of our little cultural white powder controlled substances.
Coca Cola's marketing was driven around it's elixir effects and used to treat a wide variety of life's little ills: upset stomachs in toddlers and adults, teething pain, headaches, bloat, gas .....
I'm sure for economic reasons alone, perigoric was removed from the forumula.
When I have an upset stomach, I get a Coke, knowing full well it will provide absolutely NO scientific relief.
Call it the miracle of the belch. /forums/images/graemlins/grin.gif
