Evidence Summary

Green tea extract, primarily through its catechin EGCG, shows preliminary evidence for reducing colorectal polyp enlargement in familial adenomatous polyposis patients (PMID: 41772671), improving periodontal clinical parameters as an adjunct to scaling and root planing (PMID: 40546664), and demonstrating antiviral activity against Zika virus in blood matrices (PMID: 41901787). A proof-of-concept trial in APOE-ε4 carriers with subjective cognitive decline found that EGCG combined with a multimodal lifestyle intervention showed exploratory cognitive benefits after a washout period, though the primary endpoint was not met (PMID: 40664536).
