Green tea originated in ancient China and was discovered accidentally when Chinese Emperor Shennong drank water in which tea leaves had been boiled. He noticed its refreshing taste, leading to the creation of one of the world’s most popular beverages.
it is made from the leaves of the Camellia sinensis plant. Unlike many other teas, it is produced from unoxidized leaves, making it one of the least processed forms of tea. This minimal processing helps preserve its antioxidants and polyphenols, which contribute to its health-supporting properties.
The leaves are harvested and quickly heated, then dried to prevent oxidation. Without this process, the leaves would turn brown.
