Anti-epileptic Action of Thymoquinone
A number of studies have been carried out to establish the anti-epileptic activity of N. sativa. Thymoquinone (TQ) is found in volatile oil of the plant and is considered the main constituent responsible for its anti-epileptic effect. Mechanism of action of TQ on seizures is not completely established; however some researchers believe that it produces anticonvulsant effect by interacting with gamma-aminobutyric acid (GABA). Some researchers in their study found that the co-administration of TQ and some known anti-epileptic drugs led to the potentiation of their anti-epileptic effect and suppressed their adverse effects.
