Research highlights EGCG's potent anticancer properties, inhibiting tumorigenesis through various mechanisms. It curbs tumorigenesis by addressing hyperinsulinemia and reducing inflammation. EGCG also combats tumor growth by stopping angiogenesis. Its phenol rings function as robust electron traps and free radical scavengers, suppressing reactive oxygen species and alleviating oxidative stress. Its ability to combat oxidative stress is documented in many studies, alongside its role in enhancing mitochondrial function.

EGCG also targets viruses, mold, fungus, yeast, and bacteria, making it an excellent choice for chronic infections. Furthermore, its robust anti-inflammatory and antioxidant properties suggest it could benefit and modulate inflammation.
