Time course of hypotensive activity after oral administration of tea polyphenols (Polyphenon CG) to SHRs. ⚫, Distilled water (control); ○, Ameal; ▲, Polyphenon CG in Ameal; △, Polyphenon CG in distilled water. The vertical axis represents changes in SBP from time zero. Changes in SBP from time zero are expressed as the mean ± SD, 𝑛=7. The baseline SBP before administration was 198.2 ± 3.0 mmHg (*𝑃<0.05, **𝑃<0.01 cosmpared to distilled water, Dunnett’s test).
