The effect of increasing concentrations of pomegranate extract on G. lamblia cysts’ viability at different exposure times compared to metronidazole (50 μg/mL). Each treatment was performed in triplicate and asterisks (*) indicate a significant increase in percentage of dead cysts compared to untreated control (p < 0.001).
