This work aimed to verify the effects of acute intravenous applications of Allium sativum and Cymbopogon citratus hydroalcoholic extracts on arterial blood pressure of anesthetized rats. Adult male rats (Rattus novergicus albinus), n=7, were used. The rats were anesthetized, tracheotomy and cannulation of both jugular and carotid were carried out. The injected doses were 1 mg separately as well as the association of both extracts, in volumes of 0,2 mL. The mean arterial blood pressure (MAP) was recorded with a Biopac System, model MP100. The Allium sativum decreased the MAP only from 124±2 mmHg (control) to 108±2 mmHg at 15s. The Cymbopogon citratus also decreased the MAP from 122±2 mmHg (control) to 106±2 mmHg after 15s. The 1mg of Allium sativum + 1mg of Cymbopogon citratus also decreased the MAP from 126±3 mmHg (control) to 113±3 mmHg after 15s. The effects of the two plants were the same and were not increased when in association.
