**4. Future prospects**

Green tea has a unique blend of health benefits due to its bioactive components shown in **Table 1**. As a result, green tea has higher concentrations of phenolic acids, quercetin, rutin, theanine, and chlorophyll than other varieties. It is an entirely new product that cannot be compared to any other green tea on the market today. The administration of its infusions and extracts may be effective in the prevention of free radicals and inflammatory disorders, as well as premature aging.

benefits have not been properly studied. Several elements of its function, including its interactions with the gut microbiota and its impact on infectious diseases, warrant further study in this area. More research will be needed to prove the health benefits of green tea, including further examination of green tea's chemical composition, and further *in vitro* and *in vivo* studies. Additional randomized clinical trials (RCT) research is also required. Moreover, pharmacodynamic and pharmacokinetic aspects of identified compounds should be investigated to validate their actions and well as their bioavailability. On the other hand, toxicological investigations of green tea main compounds should be carried out with different doses and several periods to validate their safety.
