Black tea , like green, white and oolong tea, is made from the leaves of the Camellia sinensis. Black tea, however, is oxidized more than other types of tea made from this plant, giving its color and name. All teas made from the Camellia sinensis have different levels and varieties of polyphenols , Antioxidants with a list of possible health benefits. Drinking enough tea to gain from these supposed benefits could be difficult; thus, extracts that preserve the active ingredients of black tea are available. Black tea extract is available in different forms, each of which could have potential advantages to one’s overall health.
Black tea extract can be purchased as pills, which include the powder form of the extract, or as tinctures mixed with water and sometimes alcohol. No studies have conclusively proved that either form has substantial health effects; thus, this extract is not recommended to treat disease or sickness. As a dietary supplement, however, it can provide many advantages.
There are five types of polyphenols, and they can each be found at different levels and chemical structures in various teas. While black tea shares many similar qualities of its more popular dietary supplement, green tea , black tea has lower levels of these supposedly healthful antioxidants. Green tea can have 30- to 40-percent of polyphenols, while black tea may contain only 3 to 10 percent due to the way it is processed.
