Evaluation of the anticonvulsant activity of the essential oil of Eugenia caryophyllata in male mice.

In this study, the effect of an essential oil of Eugenia caryophyllata (Myrtaceae), an antiepileptic remedy in Iranian folk medicine, against seizures induced by maximal electroshock (MES) or pentylenetetrazole (PTZ) in male mice was studied. The essential oil exhibited anticonvulsant activity against tonic seizures induced by MES. Although it was not effective against clonic convulsions induced by intraperitoneal administration of PTZ, the seizure threshold which was determined by an increase in the dose of intravenously infused PTZ required to induce clonus, was elevated by the essential oil. In addition, at some anticonvulsant doses, the essential oil produced motor impairment on the rotarod.
