Consumption of <i>Hibiscus sabdariffa</i> L. aqueous extract and its impact on systemic antioxidant potential in healthy subjects

Abstract

The aqueous HSE investigated in this study enhanced the systemic AOP and reduced the oxidative stress in humans. Furthermore, the increased urinary hippuric acid excretion after HSE consumption indicates a high biotransformation of the ingested HSE polyphenols, most likely caused by the colonic microbiota.
