I have loved Coca-Cola ever since I was little!  It brings good memories to mind!
Yes, Coca-Cola has been around since the 19th century! Of course it was designed for medicine then.
It was designed for medicine?  What was it prescribed for?
Well, two original ingredients were kola nuts (basically caffeine) and coca leaves. This combo was thought to help with many medical ailments.
Interesting!  Was it actually effective or just a ploy?
Well, as Coca leaves are used to make cocaine, it was actually unknowingly making the consumers addicts back then. Of course, they have changed the formula!
