Background: Stroke is a neurological deficit due to vascular disorders. Microglia are the first line of defense against brain injury. Anti-inflammatory cytokines activate M2 microglia, which upregulate CD206. EGCG is abundant in green tea, which has an anti-inflammatory effect. Objective: To know the effect of green tea with its active compound EGCG on CD206 expression. Settings and Design: True experimental trial design. Material and Methods: Rattus Novergicus were divided into six groups: a negative control group (Sham), a positive control group (P0), MCAO mice given 10 mg/kg BW EGCG (P1), 20 mg/kg BW EGCG (P2), 30 mg/kg BW EGCG (P3), and 30 mg/kg BW standardized green tea extract (P4). CD206 expression was measured using immunohistochemistry and scored according to the Allred scoring guidelines. Statistical Analysis Used: Descriptive test, Levine test, Kolmogorov–Smirnoff test, Independent sample t test, Pearson correlation test Results: We discovered that there is a significant difference in CD206 expression between the Sham and P0 groups (P < 0.05). In addition, there are significant differences in expression between the sham group and the other two groups (P1 and P2) (P < 0.05). Furthermore, when we compared the P0 group with each treatment group, we found that CD206 expression between P0–P2, P0–P3, P0–P4 are significantly different. There is a significant correlation between green tea with its active compound EGCG and CD206 expression enhancement. The correlation is positive. Conclusions: Green tea with EGCG active compound increases CD206 expression as an M2 marker in the Rattus norvegicus with MCAO model.
