How was Cadbury used when it first invented?

Cadbury was originally used as a medicine.

John Cadbury, a Quaker from Birmingham, England, opened a shop in 1824 that sold tea, coffee, spices, and drugs. One of the drugs he sold was cocoa, which was then being promoted as a health food. Cadbury believed that cocoa had medicinal properties and began experimenting with adding milk and sugar to it. He found that this made the cocoa more palatable and easier to digest.

In 1831, Cadbury opened a factory to produce his cocoa drink. He originally sold it as a liquid, but in 1842 he began selling it in solid form as "Cadbury's Drinking Chocolate." The chocolate was a success and the company began to produce other chocolate products, including chocolate bars, Easter eggs, and Christmas chocolates.

By the late 19th century, Cadbury was one of the leading chocolate manufacturers in the world. The company continued to grow and innovate, and today it is one of the most well-known chocolate brands in the world.
