GB Sonara*, DP Shah, TN Gheewala and SP Roy

Tea is the second most widely consumed beverage in the world, with only water being more common. There are many different types of teas available today, most of which have wonderful health benefits. Different types of tea, such as white tea, green tea, yellow tea, black tea, oolong tea and pu-erh tea, all come from the same plant, Camellia sinensis. The type of tea produced from this plant depends entirely on the way the leaves are processed after harvesting. .

The health benefits of tea for a wide variety of ailments, including different types of cancer, heart disease, liver and kidney disease, Kidney were reported there is evidence from in vitro and animal studies on the underlying mechanisms of tea catechins and their biological actions. There are also human studies on using tea catechins to treat metabolic syndrome, such as obesity, type II diabetes, and cardiovascular risk factors. Long-term consumption of tea catechins could be beneficial against high-fat diet-induced obesity and type II diabetes and could reduce the risk of coronary disease. Further research that conforms to international standards should be performed to monitor the pharmacological and clinical effects of tea and to elucidate its mechanisms of action.
