Methods: Initially, essential oil of the plant fruit was extracted to study the acute toxicity to rats by gavage. The animals were treated with 1000 mg/kg of the essential oil for 23 and 45 days to determine chronic. Hematological and biochemical parameters of rats’ blood samples were collected and spleen, kidney, liver and lung of rats were isolated for histopathologic examination.
Results: According to acute studies result lethal dose, 50% (LD50) of ajowan essential oil was about 2294 mg/kg. Chronic evaluation showed that there is no statistical difference between weight, food and water consumption of test and control groups.
