How was cola originally sold?

How many of you drink cola? Nearly everybody. Did you know the cola started out not as a soft drink, but as a cure for headache back late in eighteen hundreds?
     John S. Pemberton, a druggist from Atlanta had experimented for many months trying to find a cure for the common headache. He worked in his backyard mixing and heating different combination of oils and flavors until he found one which seemed promising. Pemberton bottled the mixture and began selling it in drugstores as a concentrated syrup that the customers had to mix with water before drinking. Cold’s transformation from a medical syrup to a carbonated syrup drink came about quite by accident. One day, a customer came into a drug store complaining of the headache, and asked for a bottle of cola syrup. He wanted to take it right away, so he asked the clerk to mix the medicine while he waited. The clerk, instead of walking to the other end of the counter to get plain water, suggested mixing the syrup with soda water. The customer agreed. And after drinking it he remarked bow good it tasted. The clerk continued offering the mix, and combinative colas grew into popularity.
     Today, carbonated colas are sold in most countries around the world. And although they no longer contain the ingredients to kill headaches, they are still very refreshing.
