Abstract
Tea is regarded as a functional food because, in addition to its nutritional benefits, it can provide other advantages via its application in the treatment of several illnesses including both communicable and noncommunicable human diseases. Tea and its metabolites are well known to inhibit the growth of the virus, bacteria, fungi, and different parasites which plays a major role in various communicable diseases. In addition, they also hold both preventive and therapeutic potential over different noncommunicable diseases that include but are not limited to cancer, arthritis, cardiovascular diseases, respiratory disorders, and diabetes, etc. Green tea metabolites including catechins and polyphenols have a limited bioavailability, and there haven’t been enough clinical trials of them to go very far, even though most preclinical research has revealed a correlation between increasing green tea consumption and a decreased risk of human diseases. Thus, new formulations of green tea metabolites are urgently needed to overcome their low bioavailability and increase their beneficial effects.
