Tea originated as a medicinal drink in southwest China. It is primarily made from boiling water over Camellia sinesis leaves. This shrub is native to Asia. Merchants slowly introduced it to western nations during the 1500’s. As you probably know, drinking tea and “tea time” became quite the past-time in Britain. Thanks to this development, Britons intitated mass production and commercialized the plant in India. This bypassed the Chinese monopoly altogether and catapulted tea to global prominence. It is now perceived as one of United Kingdom’s cultural beverages.
In recent years, tea has rapidly grown in popularity as an alternative to drinking coffee. Some advocates make the case that tea provides a heightened, calm alertness rather than the jittery feeling of coffee. On average, black tea and green tea contains about 25 mg caffeine per 100 g of brewed tea leaves. Despite some rumours, plain black and green teas do not cannot any other essential nutrients other than manganese. However, manganese is important for human health. It is necessary for the healthy functioning of the metabolism, antioxidant system, and some other bodily functions. In particular, it is integral part of the antioxidant process which have led some to believe it may protect against cancer.
It should be noted that “herbal teas” or “herbal infusions” typically do not contain any Camellia sinesis. These products are usually infused with herbs or fruits such as chamomile. Purists consider only select green and black teas to be authentic teas.
