Green tea has emerged as one of the most desired drinks in the world today, all because of its soothing nature and impressive health benefits.

With having a much higher amount of antioxidants as compared to other teas, green tea is greatly admired for its ability to uplift both the body and the mind.

Green tea is brewed from the dried leaves of Camellia Sinensis, a plant native to India and China but widely used throughout Asia. The plant has been known for its amazing medicinal properties for thousands of years.
