prevents seizures and memory deficit via inhibition of oxidative stress and neuronal loss in the hippocampus.

Mesiotemporal lobe epilepsy is the most refractory form of epilepsy. The management of this condition relies on the use of antiepileptic drugs known to provide symptomatic relief. Herbal remedies are therefore an alternative to finding a cure for epilepsy. The present study aimed to assess the antiepileptic and anti-amnesic effects of aqueous extract using the pentylenetetrazole (PTZ) kindling model in rats. For this, 48 rats were divided into 6 groups of 8 animals each and treated as follows: normal and negative controls received (p.o) distilled water (10 mL/kg); experimental groups received extract (17.14, 34.28, and 68.56 mg/kg, p.o); and positive control group received levetiracetam (250 mg/kg, p.o). One hour after the treatments, animals intraperitoneally (i.p) received a subconvulsive dose of PTZ (25 mg/kg), except the normal control group. The animals were treated once daily until the onset of the first tonic-clonic seizure (stage 5) in the negative control group. Twenty-four hours following the onset of the first seizure, memory impairment was assessed. Twenty-four hours later, the animals were sacrificed, and the hippocampus and prefrontal cortex were collected for biochemical analyses. The extract (68.56 mg/kg) prevented (p < 0.001) seizures from day 1 to day 12 compared to the negative control group. The extract (17.14 and 34.28 mg/kg) increased the recognition index by 80 % (p < 0.05) and 60 % (p < 0.01), respectively, compared with the negative control group. Moreover, the extract (17.14 mg/kg) increased by 68 % (p < 0.001) the concentration of GABA in the hippocampus. The extract (17.14 and 34.28 mg/kg) increased the acetylcholine level by 51 % (p < 0.001) and 69 % (p < 0.001) in the hippocampus, respectively. The extract at a dose of 17.14 mg/kg decreased the concentration of MDA in the hippocampus by 43 % (p < 0.001). These findings suggest that the extract has antiepileptic and anti-amnesic potentials that could justify its empirical use.
