This study aims to evaluate the effect of
Artemisia herba alba
(Ah) intravenous injection on cardiovascular and renal function
in normal rats. Intravenous bolus injection of Ah at the different doses of 50, 100 an 200 mg/kg produced a dose dependent
reduction in arterial blood pressure (p<0.001). A significant reduction in heart frequency was observed after Ah injection at the
doses of 100 and 200 mg/kg (p<0.001). Perfusion of aqueous Ah extract at a dose of 200 mg/kg/h caused a significant increase
in urine output after three hours of perfusion (p<0.001). In addition, a significant increase in urinary sodium and potassium
excretion was observed from the first (p<0.05) to the third hour (p<0.001) of Ah perfusion. Urinary chlorure excretion was
increased after two hours of perfusion (p<0.001). However, glomerular filtration rate remained unchanged after Ah perfusion
(p<0.05). We conclude that the aqueous Ah extract possess a potent acute hypotensive effect in normal rats. In addition, Ah
perfusion may affect renal function to increase urine and electrolytes excretion.
