Tea leaves (Camellia sinensis) are shrubs or small trees that come from East Asia and are widely cultivated in mountainous areas with cool climates. This plant can grow up to 2–10 meters tall if not pruned, but in plantations, it is usually kept around 1–1.5 meters to make harvesting easier. The leaves are oval to lance-shaped, shiny green, have finely serrated edges, and are alternately arranged on the stem. Tea flowers are yellowish-white with yellow stamens, while the fruit is a small round shape that contains seeds.
Tea leaves contain various bioactive compounds such as polyphenols (mainly catechins), flavonoids, tannins, caffeine, theanine, as well as vitamins and minerals that play an important role in providing health benefits.
