Black Tea Theaflavins are extracted from Black Tea, and theaflavins are the first compounds with an exact pharmacological effect to be found from tea. Through clinical trials, Black Tea Theaflavins has been verified to regulate blood lipids and prevent cardiovascular diseases, and has no side effects. This research report has been published in the international leading medical journal JAMA. Theaflavin, known as the "soft gold" in tea, has the unique function of lowering blood lipids. Theaflavin can not only combine with cholesterol in the intestine to reduce the absorption of cholesterol in food, but also inhibit the synthesis of cholesterol in the human body. Due to the extremely low content of theaflavin in tea, the extraction cost is extremely expensive, and it is widely used in production and made into health food with the function of regulating blood lipids and health care, it is necessary to use patented biotechnology, while overcoming the shortcomings of natural products in efficacy and safety evaluation, production technology, quality standards, preparation technology, clinical application and other aspects of development lag, so as to make the production scientific and standardized.
