Fifty hamsters were divided into five groups: Group (A): normal control. Group (B): Giardia lamblia infected and untreated hamsters served as control. Group (C): infected with Giardia lamblia and treated with metronidazole in dose (120 μg/kg body weight twice daily for 7 successive days). Group (D) Giardia lamblia infected and orally treated with Myrrh (500 mg/Kg for 1 week). Group (E): Giardia lamblia infected and orally treated with combination 1/3 dose of (120 μg/kg body weight) metronidazole and Myrrh (250 mg/Kg) for 1 week). After 2 weeks of the treatment, hamsters were sacrificed. The highest percentages of reduction in the number of Giardia lamblia cysts and trophozoites were in the group receiving combined metronidazole and myrrh.
