Green tea contains catechins like EGCG which act as antimicrobial and anti-inflammatory agents within the oral cavity. By reducing the burden of pathogenic bacteria, such as P. gingivalis, this rinse may lower systemic inflammation, a key driver of age-related diseases like atherosclerosis and neurodegeneration.
