Allium sativum Linn is a popular Indian herb which is used as Antimicrobial, Anticancer, Antioxidant, Antiadrogenic,
Hepatoprotective, Anticoagulant, Hypocholestermic, Antiarthritic, Antihypertensive etc. The aim of present study was to
evaluate anticonvulsant activity of EEAS (Ethanolic Exctract of Allium sativum Linn) against MES and Isoniazid
(INH300mg/kg i.p) induced convulsions in wistar rat. All the animals were divided into five groups of six rat each (n=6)
induced by MES and INH (300mg/kg intraperitonially) convulsions respectively. In method I Group I treated as control, Group
II was induced by MES. Group III was treated with Phenytoin(25mg/kg b.w.p.o) and MES Group IV was treated with EEAS
(200 mg/kg p.o.) and MES. Group V was treated with EEAS (400mg/kg p.o.) and MES. In Method II Group I was treated as
control, Group II was induced with INH 300mg/kg i.p.\Group III was treated with Phenytoin(25mg/kg b.w.p.o) and INH
(300mg/kg intraperitonially), Group IV was treated with EEAS (200 mg/kg p.o.) and INH (300mg/kg intraperitonially), Group
V was treated with EEAS (400 mg/kg p.o.) and INH (300mg/kg intraperitonially) respectively. The result showed that EEAS
significantly reduced duration of clonic convulsions in MES and also delayed the onset of convulsions induced by INH. EEAS
showed anticonvulsant activity in MES and INH induced convulsions in animals. Brain homogenate of GABA, Histopathology
and Antioxidant SOD, LPO, GPx, Catalase were estimated.
