Hypotensive effect of Chamaemelum nobile aqueous extract in spontaneously hypertensive rats

Clin Exp Hypertens. 2009 Jul;31(5):440-50. doi: 10.1080/10641960902825453.

Abstract

This study aims to evaluate the hypotensive effect of Chamaemelum nobile aqueous extract (CNAE) in spontaneously hypertensive rats (SHRs). Single oral administration of CNAE (140 mg/kg) produced a significant reduction (p < 0.05) in systolic blood pressure (SBP) after 24 h of the administration. Daily oral administration of CNAE (140 mg/kg) during 3 weeks produced a significant reduction in SBP in the day 8 (p < 0.01) of treatment. Furthermore, CNAE produced a significant increase in urinary output and electrolytes excretion (p < 0.01) from the day 8 to the end of treatment. We conclude that CNAE possesses a hypotensive and diuretic effect in SHR.
