Evaluation of anticonvulsant effects of methanolic extract of2015 •
Preparations of Olax subscorpioidea have been used in the Nigerian traditional medicine for the management of convulsions, mental illness, pains, cancer and microbial infections. The efficacy of the leaves of this plant in management of convulsions has been widely acclaimed among the Igala communities of North-Central part of Nigeria and therefore, this study was aimed at examining the anticonvulsant effects of methanolic extract of O. subscorpioidea (MEOS) leaves in order to provide scientific basis for its use in management of convulsions. Phytochemical screening and evaluation of intraperitoneal median lethal dose of the extract was carried out. Anticonvulsant activity of MEOS was evaluated in chicks using maximal electroshock test, and in mice using pentylenetetrazole and strychnine-induced seizure models at doses of 100, 200 and 400 mg/kg. The intraperitoneal median lethal dose of MEOS was estimated to be 3800 mg/kg body weight in mice. MEOS at doses of 100 and 200 mg/kg provided 30 and 70% protection against maximum electroshock induced seizures respectively. The extract also significantly (p < 0.05) increased the mean latency to seizures in a dose dependent manner. MEOS at 100 mg/kg provided 50% protection against strychnine-induced seizures. A significant increase (p < 0.01) and (p < 0.05) in the mean onset of strychnine-induced seizures was also observed with MEOS at doses of 200 and 400 mg/kg respectively. These findings suggest that the methanolic extract of Olax subscorpioidea leaves possess anticonvulsant activity.

Anticonvulsant Properties of Some Medicinal Plants- a ReviewIntroduction: Epilepsy is the tendency to have seizures that start in the brain. The brain uses electrical signals to pass messages between brain cells and when these signals are disrupted, it leads to a seizure. A number of synthetic antiepileptic drugs are available in practice, but various medicinal plants act as an important source of treatment for epilepsy; plants such as Aeollanthus suaveolens, Passiflora caerulea, Persea americana, Annona diversifolia, and Boerhavia diffusa have good anticonvulsant activity.Objective: Anticonvulsant drugs are used to control the convulsions by inhibiting the discharge and then producing hypnosis. The objective is to understand various medicinal plants and plant components, which are being used as an anticonvulsant.Results: A. suaveolens essential oils are the main constituents were deemed to display anticonvulsant activity. P. caerulea is reputed to have herbal activity as a sedative and anticonvulsant and it is often used as a relatively dis...

Plants with anticonvulsant properties: a review2008 •
Seizures are resistant to treatment with currently available anticonvulsant drugs in about 1 out of 3 patients with epilepsy. Thus, there is a need for new, more effective anticonvulsant drugs for intractable epilepsy. However, nature is a rich source of biological and chemical diversity and a number of plants in the world have been used in traditional medicine remedies, i.e., anticonvulsant, anxiolytic, analgesic, antidepressant. This work constitutes a literature review on medicinal plants showing anticonvulsant properties. The review refers to 16 Brazilian plants and a total 355 species, their families, geographical distribution, the utilized parts, method and references. Some aspects of research on medicinal plants and a brief review of the most common animal models to discover antiepileptic drugs are discussed. For this purpose over 170 references were consulted.

Anticonvulsant activity of the methanol root bark extract of Ficus sycomorus Linn. (Moraceae)Context: Ficus sycomorus Linn. (Moraceae) is used in Northern Nigeria for the management of grand mal epilepsy without any scientific validation. Aims: To evaluate the phytochemical constituents, acute toxicity study and anticonvulsant properties of the methanol root bark extract of F. sycomorus. Methods: The basic phytochemical screening, Lorke’s method and three models of epilepsy were employed, which include the maximal electroshock test in chicks, and pentylenetetrazole- and 4-aminopyridine-induced seizures in mice. Results: The extract revealed the presence of tannins, saponins, carbohydrate, alkaloids, flavonoids, steroids, terpenoids and cardiac glycosides. The intraperitoneal LD50 in mice was estimated to be 565.69 mg/kg body weight. The extract afforded a slight protection, 30% (highest dose used) to the laboratory animals against the maximal electroshock test. The duration of convulsion decreased, which was not statistically significant (p>0.05) when compared to the untreated group. Also, the extract did not protect the animals against the chemically induced seizures by pentylenetetrazole and 4-aminopyridine. Conclusions: The data suggest that the methanol root bark extract of F. sycomorus, at the doses tested and under the experimental conditions reported, may not contain psychoactive principles that are relevant to the management of grand mal epilepsy as claimed by the traditional medicine practitioners.

Validation of anticonvulsant and sedative activity of six medicinal plants2009 •
Acanthus montanus, Alchornea laxiflora, Hyptis spicigera, Microglossa pyrifolia, Piliostigma reticulatum, and Voacanga africana were evaluated with respect to anticonvulsant and sedative activity in mice using animal models (maximal electroshock (MES), N-methyl-D-aspartate (NMDA), pentylenetetrazol (PTZ), isonicotinic hydrazide acid (INH), picrotoxin (PIC), and strychnine (STR)-induced convulsions or turning behavior and diazepam-induced sleep). Acanthus montanus protected 66.6% of mice against MES-, PIC-, and STR-induced convulsions and 83.3% of mice from PTZ-induced convulsions. Alchornea laxiflora protected 75% and 87.5% of mice in the STR and NMDA tests, respectively, at a dose of 120 mg/kg. Hyptis spicigera protected 100 and 87.5% of mice against STR- and PTZ-induced convulsions, respectively, at a dose of 160 mg/kg. Microglossa pyrifolia protected 50% to 100% of mice against convulsions. Piliostigma reticulatum protected 62.5% to 100% of mice against convulsions and turning be...
Epilepsy, which comprises a large array of neurological abnormalities and responsible for almost one percent of the global burden of chronic disease directly affecting individuals of different ages, is regarded as an "Apasmara" in the Indian traditional system of medicine widely known as Ayurveda. The limited availability, high prices, low potency, and adverse events of anti-epileptic drugs (AEDs) are all critical challenge. Herbal medicine has classically been aspect of epilepsy therapy, is generally safe, with minimal side effects. To showcase some natural herbs which have been evaluated in preclinical studies for their antiepileptic efficacy, a review of literature via PubMed as well as Science Direct was therefore pursued. The studies basically consisted of phenotypic model tests, with really no uniqueness of screening tools. In some studies, the extracts tested prolonged the time to onset of epileptic fits and decreased the span of seizures. Most investigators imply potentiation of GABAergic activity as the mechanism of action of the extract, even if some researchers haven't yet entirely established the bioactive molecular structure of the crude extract.
