Which product was originally marketed as an esteemed brain tonic and intellectual beverage?

Answer

The answer is Coca Cola

Explanation

The history of Coca-Cola goes back to the 19th Century when the chemist  John Stith Pemberton invented the first Coca-Cola to be sold at his store.

At the time, Coca-Cola was developed and marketed as ‘Brain Tonic’ and a drink that helps patients with headaches refreshes them, and improves their mood.

At the time, John Stith did not intend it to be a fizzy drink in the modern sense and was actually promoted as a ‘mild medicine’.

Unfortunately, he was never able to see the real success of the company and before his death, sold the rights of Coca-Cola to another businessman.
