Green Tea
Green tea, scientifically known as Camellia sinensis, is a beverage derived from the unoxidised leaves of the tea plant, originating from China and Japan. It has been consumed for centuries, not only for its refreshing taste but also for its numerous health benefits. Rich in polyphenols, particularly catechins like epigallocatechin gallate (EGCG), green tea is renowned for its potent antioxidant properties, which help combat oxidative stress and inflammation.
Traditionally, green tea has been used to support weight management, enhance cognitive function, and improve heart health. Recent studies have also suggested that regular consumption may lower the risk of certain chronic diseases, including cardiovascular disease and certain types of cancer. Green tea is typically consumed as a brewed beverage, with supplements available in capsule or extract form.
