Introduction: According to the traditional beliefs of certain cultures, Lawsonia inermis has been reported to cause the abortion or termination of an undesirable pregnancy. The present study was undertaken with the goal of studying the effect of Lawsonia inermis extract on abortion in pregnant BALB/c mice in 2013 in Shahrekord, Iran.

Methods: This research study used an experimental methodology and was conducted in 2013 in Shahrekord, Iran. Forty female BALB/c mice (30-40 gm, 8-12 weeks old) were randomly assigned to 4 groups. One male mouse was included for each two female mice (1:2) and they were maintained in a protective cage habitat. Pregnancy of the mice was confirmed by means of a vaginal smear. The doses of 1 mg/kg and 10 mg/kg of the hydroalcoholic extract of Lawsonia inermis were injected intraperitoneally into pregnant mice beginning on the first day and continuing through the seventh day of pregnancy. The control group did not receive any treatment, but was left completely unadministered. On the eighteenth day of pregnancy, the uterine tubes of mice were removed. The subsequent embryonic absorption is considered to be an abortion. The data were analyzed using SPSS software version 22 using Fisher’s exact test and the Kruskal-Wallis H tests.

Results: Abortions were observed more often in the experimental groups (p< 0.01).The mean of the serum estrogen level was significantly higher in the case control groups (p< 0.01) and the mean of progesterone level was also significantly lower in the experimental groups (p< 0.01).

Conclusion: The use of Lawsonia inermis during pregnancy may cause abortion and therefore it should be considered as contraindication or use with caution.
