Green tea antioxidants are attracting increasing attention due to their potential for application in preventive medicine and in the food industry, as well as their pharmacological effectiveness and lack of adverse effects. Growing awareness of antioxidant phytoconstituents and their use in diet and daily use may provide the human body with potential support to combat these diseases. Green tea is becoming a natural remedy for a wide range of health issues. With the latest technological advancements, the different abilities of green tea have been explored. Recent use of green tea in nanotechnology has indicated promising evidence for its bioavailability using lipid nanocapsules and liposome encapsulation to deliver EGCG. These results are encouraging. Many of these properties of green tea have been discovered through numerous preclinical studies, and there is still a lack of human clinical evidence for them. Thus for green tea to be used as a safe and effective medicine, there is an urgent need to test the efficacy, health, and translation guidelines.
