- Toxicity of C.cyminum's essential oil was explored in healthy female Wistar rats.
- C.cyminum had no observed adverse effects on some clinical and biological variables.
- Serum levels of alanine transaminase increased only at dose level of 1000Â mg/kg/day.
- The non-observed adverse effect level for C.cyminum was defined as 500Â mg/kg/day.
The current study was performed to evaluate the toxicity of Cuminum cyminum L. (C. cyminum)'s essential oil after 23 days and 45 days of repeated oral administration in female Wistar rats. A total of 80 healthy female Wistar rats were randomly selected and divided into 4 groups. The rats were gavaged with C. cyminum's essential oil at dose levels of 0, 250, 500 and 1000 mg/kg/day. Clinical signs, body weight, hematology, serum biochemistry and organ histopathology were assessed once after 23 days and again after 45 days passed from the start of the intervention. Oral administration of C. cyminum's essential oil had no observed adverse effects on clinical signs, mortality, body weight, hematology, biochemistry and organ histology (liver, kidneys, spleen and lungs) in a sample of healthy female Wistar rats after 23 days and 45 days from the start of the study. However, an increase in serum levels of alanine transaminase (ALT) was found only at dose level of 1000 mg/kg/d C. cyminum's essential oil, after the 23-days interval. We conservatively defined the non-observed adverse effect level (NOAEL) for C. cyminum's essential oil as 500 mg/kg/d in female Wistar rats. The present study results should be treated with cautious in terms of the other organs' toxicity.
