Temporal lobe epilepsy (TLE) is the most common form of localization-related epilepsy, with the highest prevalence rate in adulthood. Recently, we reported the beneficial effects of the individual treatment with flavonoids such as silibinin and morin in kainic acid (KA)-treated mouse model for TLE. In this study, we investigated whether there is a synergistic effect of co-treatment with silibinin and morin on the susceptibility to seizure, the frequency of spontaneous recurrent seizures (SRSs), and granule cell dispersion in the dentate gyrus, which could be partially controlled by treatment with each flavonoid in the animal model for TLE. Unfortunately, we did not observe any synergistic effect against the susceptibility of seizure and SRS induced by KA treatment. However, the combination of these flavonoids showed similar antiepileptic effects compared with treatment with each one individually. Therefore, although silibinin and morin are not suitable for combination therapy, our results still suggest that these flavonoids can be used as potent therapeutic compounds for preventing epileptic seizures.
