Product Description

E.K Herb OEM Natural Organic Instant Black Tea Extract Puer Tea Extract OOlong Tea Extract Powder Ceylon Black Tea Powder

Dark tea extract is of course derived from the powdered leaves of dark tea. These leaves in turn come from a plant called Camellia sinensis. This plant, the "tea plant," is the same one which gives us green tea, oolong, white tea, and other forms. The difference between these types of tea comes down to processing, not origin. Dark tea is processed in a different way than green tea. Green tea comes from ripe, fresh leaves, while dark tea is derived from leaves which have aged in the sun. The oxidization of the leaves from the sun gives them their black color. Why is it useful to know all this? The oxidization process causes chemical changes in the leaves as well.     Green tea contained EGCG, a special antioxidant. Dark tea however contains an abundance of compounds called theaflavins. Theaflavins, like EGCG, fight free radicals and reduce inflammation. We'll tell you more about how that helps to enhance beauty shortly.
