As human science and technology develop more and more advanced, the temperature of the earth is getting higher and higher. In the summer, after playing basketball or doing other sports, you go to a nearby store to buy a bottle of ice-cold Coca-Cola and drink it. The sweet, astringent and weird taste is really satisfying. So Coca-Cola became almost popular all over the world in the summer, but did you know that this best-selling drink that took the world by storm was originally a painkiller?

The inventor of the original formula of Coca-Cola was doctor John Pemberton. He studied medicine in college. After graduation, he came to his father's shop to sell medical supplies. At that time, people were suffering from various diseases, and John had been thinking, how to use drugs to achieve the pain relief effect on people? In 1885, he saw a piece of news in a newspaper the previous year: a substance called cocaine can be extracted from the coca tree, which can relieve pain.

John, who dared to think and act, felt that this might be a very important opportunity. He hoped to use this coca tree to create a painkiller that could relieve people's pain, so he purchased a large amount of coca. He extracted cocaine from the leaves of the tree. After repeated experiments, he finally extracted a liquid containing carbonic acid and cocaine, which appeared dark green. John first tried the taste of this "painkiller" himself. It was a bit uncomfortable in his mouth, but he had an endless aftertaste.

This strange-tasting painkiller quickly became popular among the crowd. Some people even came to buy this painkiller without any pain symptoms. But it was an employee mistake that really made John's painkillers a hit. One afternoon, while the bored employees were sleeping on their desks, a drunk man ran in and asked the employees for painkillers. The employee who had just woken up from his sweet dream was ready to give him medicine.

Rubbing his drowsy eyes, the employee prepared the ready-made medicine and mixed it with water. But the employee hadn't woken up at this time. After searching for a long time, he couldn't find the water he needed, so he picked up the liquid from a cup on the side and poured it in. The painkiller prepared this time was different from the previous painkiller. This time it was dark red. The drunkard took the crimson painkiller and drank it in one gulp. He felt so good that he asked for several more.

Someone came over from behind and asked John specifically for "dark red painkillers". After many inquiries, John learned about "dark red painkillers" from his employees. What was the situation? It turns out that The busy employees did not add water to the painkillers, but added soda water, so that the green painkillers turned into dark red soda water. In 1887, John registered the "Coca-Cola Syrup and Concentrate" trademark with the U.S. Patent Office and obtained intellectual property rights. John's "Red Painkiller" quickly became a hit.

In 1888, the big businessman Candler came to John's shop. He was recommended because he suffered from severe headaches and suffered constant pain all year round. In order to relieve his pain, he decided to try his luck here. After drinking John's red painkiller, he felt it tasted great and the pain was gone. Candler was a business-minded person. He felt that this was not only a painkiller, but also a huge business opportunity. He asked John to sell him the patent.

Of course John did not agree. This formula made his shop make a lot of money every year. Now that he has given the prescription to others, how can he buy medicine for himself in the future? However, what John didn't expect was that while he was still hesitating, his son made the decision for him and sold the property rights of the drink to Candler for $2,300.

Candler has since mastered all the sales rights of Coca-Cola. He has changed the sales model of Coca-Cola. He no longer opens a store to sell it by himself, but makes Coca-Cola liquid and distributes it to other businessmen to help him sell it. , which greatly increased sales and increased the popularity of Coca-Cola. At the same time, he also came to train stations and towns to advertise Coca-Cola. He made a lot of money from Coca-Cola.

But Candler did not have the last laugh. In 1919, his son also sold the property rights of Coca-Cola to another businessman for US$2.5 million without his knowledge. From then on, Coke became popular all over the world. Candler burst into tears when he learned about it, and finally died in depression.
