    Medicinal plants with diuretic activity currently occupy a place as an alternative therapy to pharmaceutical drugs. Objective: To determine the diuretic activity of the hydroalcoholic extract from the dry leaves of Baccharis genistelloides (Lam.) Pers. (Carqueja) in Holtzman strain albino rats. Materials and method: 50 female rats weighing 230 to 280 g were used, employing the modified Naik et al. model. The rats were pre-hydrated with 0.9% sodium chloride (NaCl) at 50 mL/kg and distributed into five groups: Control Group (0.9% NaCl 50 mL/kg), Standard Group (furosemide 40 mg/kg), Group I (extract 200 mg/kg), Group II (extract 400 mg/kg), and Group III (extract 600 mg/kg). Urine was collected after 6 hours, followed by electrolyte dosage and the calculation of the percentage of urinary volumetric excretion (%EVU) and the percentage of diuretic activity (%AD). Results: At the sixth hour, the highest average urine volume was observed in Group III (8.63 mL). This group also showed 55.7% EVU. Regarding %AD, Group III presented the highest activity at 113.1%, which was superior to the control group. For electrolyte dosage, the observed differences in K+ and Na+ were not significant, meaning it cannot be asserted that the extract significantly alters these electrolytes, while the Cl- values of the extract groups were comparable to the control group. Conclusions: The hydroalcoholic extract from the dry leaves of Baccharis genistelloides (Lam.) Pers. (Carqueja) presented diuretic activity at all three concentrations used.
