What Is In Tea


 After water, tea is the second most highly consumed drink in the world. All types of tea come from a common plant, scientifically known as the Camellia Sinensis. It is a sub-tropical plant that grows in different parts of the Asian countries. It mainly grows in places of high altitude. Tea is primarily cultivated in two methods, including the unorthodox and the orthodox. In the unorthodox productions, modern pieces of machinery like the leaf shredder and the mower are used. The three main components of tea are – essential oils, polyphenols, and caffeine. The drink might be consumed by the entire world, but its culture is very ‘local’. Over the years, tea has developed into a cultural mark of several countries.

Origin Of Tea

The origin of tea is supposedly associated with a Chinese legend that can be traced back to BC 2750. According to this legend, Emperor Shen Nung accidentally discovered tea when he was boiling water under a tree. The tea leaves fell into the boiling and produced a beautiful aroma. The Emperor soon came to know about its medicinal properties. Since that period, China has been cultivating this crop. During the rule of the Ming and Tang Dynasty, tea was not cultivated as a cash crop. It was the Dutch who exported tea to England around 1650. 

Drinking tea soon became a mark of aristocracy in Britain, and the government started to put taxes on the sale of tea instead of liquor. Tea also played a significant role in American independence when the British colonies in America got enraged by the huge taxation on tea. During the 19th century, tea as a beverage became immensely popular and became the life of colonial parties. Cookbooks from those times had records of all the essentials required for a tea party. It was through colonialism that the tea consumption spread in India ( mainly Assam), Africa, the Zen priests of Japan carried the seeds of this plant to Japan for studying, and soon after, tea cultivation started in southwest Japan.
