Background: Epilepsy is one of the most common neurological disorders that affect social, economic and biological aspects of the human life. Many epileptic patients have uncontrolled seizures and medication-related side effects despite adequate pharmacological treatment. The use of plant extracts is proposed as a therapeutic modality in order to treat different diseases. Datura plant has long been used in the traditional medicine in regard with some nervous disorders like epilepsy. Thus, this study aimed to provide a scientific basis investigating the effect of Datura aqueous extract on PTZ-induced seizures in the male mice.

Methods: In this experimental study, 40 male mice were randomly allocated into 5 equal groups including: one control group, one sham group and three experimental groups. The experimental groups received 50, 100 and 150 mg/kg of aqueous extract of Datura Stramonium seed via gavage for 30 days, and the sham group received stilled water via gavage. Pentylenetetrazol (PTZ 35 mg/kg, i.p) were injected into control, sham and experimental groups 30 minutes after gavage in order to induce the seizure. Then latency time of seizure onset, seizure duration and seizure phases were measured and recorded in the experimental, sham and control groups. The data analysis was carried out via one way ANOVA and Tukey post-hoc tests.  Moreover, difference less than 0.05 (P<0.05) was considered significant.

Results: The study findings revealed that the aqueous extract of Datura Stramonium seed produced a significant effect on PTZ-induced seizure. In addition, Datura increases latency time of seizure onset (P˂0.01), inhibits progress of seizure stages (P˂0.05) and decreases seizure duration (P˂0.001).

Conclusion: The results obtained from the present study indicated that extract of this plant has anticonvulsant effects on PTZ-induced seizure. As a result, it seems to be beneficial to the epilepsy treatment.
