Antiviral Action of Green Tea EGCG Catechin

• Mechanism of Viral Inhibition:
• Epigallocatechin gallate (EGCG) exerts potent antiviral effects primarily by interfering with viral attachment, entry, and replication within host cells.
• It binds directly to viral surface proteins and host cell receptors, effectively blocking the virus from attaching and penetrating the cell membrane.

• Inhibition of Viral Enzymes:
• EGCG acts as a protease inhibitor, suppressing essential viral enzymes required for the virus to replicate its genetic material.
• This enzymatic disruption prevents the amplification of the viral load within the infected organism.

• Immune Support and Antioxidant Synergy:
• Beyond direct viral inactivation, EGCG provides powerful antioxidant and anti-inflammatory actions.
• By reducing oxidative stress and modulating inflammatory cytokine responses, it helps support the body's immune defense mechanisms during viral challenges.
