Tea comes in many varieties, including red tea and green tea.
Technically, to be classified tea it must come from the Camellia sinensis plant. However, several drinks people call tea, including red tea, do not come from this plant. How the plant is grown, harvested and processed will give the tea its characteristics. Many purported health benefits are associated with both red and green tea.
Green tea comes from the mature tea leaves of the Camellia sinensis plant. Green tea is unoxidized and unwilted. Green tea has many health benefits that have been confirmed through scientific study. Green tea offers antioxidant benefits, reduced risk of hypertension and reduced risk of certain types of cancers including colon, breast, skin and lung.
Green tea does contain caffeine. The exact amount of caffeine in green tea will depend on the specific variety you drink.
Rooibos, also known as red tea, is equally high in antioxidants, however sourced from
different substances to that of green tea. The antioxidants contained in rooibos – aspalathin
and nothofagin – are comparatively rare, and help to regulate blood sugar, reduce excessive
fat production, stress, and inhibit metabolic disorders.
Unlike green tea, red tea does not contain caffeine, and therefore drinking the blend at night won’t leave you restless.
Another factor of its ultimate superiority is simply – taste. The bitterness of green tea is often attributed to its high tannin content, which is less prevalent in red tea.
