A plant called Camellia sinensis produces the leaves and buds that are commonly known as tea – the most common beverage consumed in the world, second only to water. Camellia sinensis, which grows in tropical and subtropical climates, is a flowering evergreen shrub that produces small white flowers; the leaves and buds are ready to be harvested three years after the shrub is planted. Although Camellia sinensis bushes can live for more than a hundred years, harvesting leaves and buds from smaller, younger bushes is easier. Once harvested, the leaves are dried and rolled in preparation for distribution.

The five components like antioxidants, flavanols, flavonoids, catechins and polyphenols are types of  potentially beneficial vital compounds found in any black, green and white tea.

Teas can be classified by a number of distinctions, like the region in which it is grown. Sometimes the style of tea determines the characteristics of its leaves.
