Health Benefits of Green Tea - Separating Fact from Fiction

Apr 18, 2023

Green tea, derived from the Camellia sinensis plant, is a widely popular beverage that has been used for medicinal purposes in China and Japan for centuries.

Green tea is often touted for its potential health benefits, which include promoting weight loss, improving mental alertness, and relieving digestive symptoms and headaches.

Research has also shown that green tea, and its key component EGCG, may have protective effects against heart disease and cancer.
