Apasmara is a similar clinical condition to epilepsy described in all major classics of Ayurveda. Unfortunately the drugs used currently not only fail to control seizure activity in some patients, but they frequently cause side effects. Therefore an alternative therapy should be employed for the treatment and control of epilepsy due to the adverse events associated with the synthetic drugs. Ayurvedic herbs which are having lesser side effects in comparison to synthetic drugs can be a better option for the control and treatment of epilepsy .The herbs like Vacha, Sankhapuspi, Tagar, Shatavari, Kushtha etc. have been mentioned in the Ayuvedic classics for the management of Apasmara and also experimentally proved as anticonvulsant. KEYWORDS: Apasamara, Seizure, Anticonvulsant activity, Epilepsy. INTRODUCTION Epilepsy is the third most common neurologic disorder, following stroke and Alzheimer’s disease, affecting more than 50 million worldwide, and nearly 80% of the people with epilepsy are found in developing regions[1].It is a chronic non communicable disorder of the brain that affects people irrespective of their age, sex, race and ethnic background. Epilepsy is a chronic neurologic condition due to electrical disturbance resulting from a sudden and recurrent, disorderly discharge of brain cells. In epilepsy a person has recurrent, unprovoked seizures due to a chronic underlying process, not accounted for by any immediate identifiable cause. Prevalence rate in the community is 5-10 per 1000 of the population. It is even much higher in children i.e. 20-30 per 1000. The treatment of epilepsy is primarily medical and the mainstay is the use of Anti Epileptic Drugs (AED). Most of the AEDs have trivial or major side effects and many adverse drug reactions. At present there is no drug which can promise complete cure. Apasmaara is said to be one among Ashtamahagada in Ayurvedic classics owing to its fatality and bad prognosis and also included in Hridaymarmagata Vyadhi [2]. Various medicines and treatment procedures are prescribed for it. But from the ancient scriptures it is clear that it is Hetal et al. / Pharma Science Monitor 6(4), Oct-Dec 2015, 88-98 Impact factor: 0.3397/ICV: 4.10 89 a disease treatable with difficulty. The classical symptomatology of the disease Apasmaara is comparable with that of epilepsy. Apasmara arises from the aggravation of both Sareerika and Manasika Doshas and is localised in Hridaya, which is a Mahamarma. Bhela considers the seat of Mana between Siras and Talu and hence the site of pathogenesis of Apasmaara is none other than brain (located in the head) [3]. The vitiated Doshas affect brain/Kapalamajja since the symptoms can be correlated to symptoms of neurological diseases. In the present review an attempt has been made to identify the Apasmarahara (antiepileptic) herbs and formulations mentioned in the Ayurvedic classics, lexicons and compendia. MATERIALS AND METHODS Ayurvedic Samhitas, compendia and lexicons were consulted to compile the specific information about anti epileptic herbs. The available published modern literature related to the epilepsy, research journals and internet based information about the pharmacological activities is compiled and analyzed. OBSERVATION AND RESULTS Very few herbal drugs namely Vacha,Bramhi ,Kustha ,Shatavari, Rason, etc. are mentioned in Samhitas as Apasmarahar and single herbs like Mundi, Sankhapuspi ,Tagar and Bol etc are also included in various Nighantus. Bruhatrayi and Chikitsagranthas described several formulations in different dosage forms which are also summarized in the table below. Table 1.

All therapeutic text books of Ayurveda, including Brihatrayee have a very detailed description about this major clinical condition. Apasmara is the transient appearance of unconsciousness associated with loathsome activities (like frothing and abnormal postures of the body), due to perversion of memory, intellect and other psychic Hetal et al. / Pharma Science Monitor 6(4), Oct-Dec 2015, 88-98 Impact factor: 0.3397/ICV: 4.10 93 faculties. In this condition Sharirika Doshas (viz. Vata, Pitta & Kapha) along with Manasika Doshas (Rajas and Tamas) are vitiated. Management of Apasmara includes Nidana Privarjana (avoidance of causative factors), lifestyle modifications, medication, and treatment procedures. There is close relationship between Sharirika and Manasika Doshas and hence the treatment is aimed at restoration of Tridosha balance coupled with correction of Manasa Dosha. The treatment methods described in Ayurvedic classics include Daiva Vyapasraya therapies and Satvavajaya i.e., psychotherapy besides Yuktivyapasraya Chikitsa which is done through drugs, diet and counselling. After a thorough review, totally 16 single drugs were identified as having Apasmarahara property. Among these all herbs except, Bola, Padmacharini and Tailakanda are experimentally proven for their antiepileptic activity. Tikta rasa is said to possess Medhya[20] property and most of the drugs mentioned have Tikta Rasa. Ushna Virya of these drugs is also useful to alleviate Vata Dosha. Furthermore, Medhya property indicates the action of a drug on brain. The main seat of pathogenesis of Apasmara (epilepsy) can be considered as brain. Medhya rasayana drugs like Sankhapushpi are rich sources of antioxidants which are very good for the prevention of nerve cell damage and preservation of cell health [21] . Since Apasmara is produced by both Shareera and Manasa Doshas being located in the important vital point it is difficult to be treated. Hence it should be treated with Rasayana therapies. The drugs like Vacha, Sankhapushpi etc. possess Rasayana properties also. Among the formulations mentioned majority are Ghritha and Taila preparations. Substances with high lipid solubility may cross the blood-brain barrier (BBB) by simple diffusion. Brahmi Ghrita and Mahapanchagavya Ghrita are experimentally and clinically proven for their antiepileptic activity. The prime measure recommended in epilepsy is blood-letting (Siravedha) from the veins of the middle of jaw joint [22]. Table 4. PLANTS WHICH ARE EXPERIMENTALLY PROVED AS ANTICONVULSANT: No 1. 2.

CONCLUSION Apasmara is included under Manasika Vikara which resembles the symptoms of epilepsy. Recent research studies showed significant antiepileptic activity of herbs like Sankhapuspi, Vacha, Rason, Shatavari, Vrudhadaru, Tagar etc. Certain formulations namely Brahmi Ghrita and Mahapanchagavya Ghrita are also proved experimentally and clinically for their anticonvulsant activity. It appears that these drugs are more useful in petit mal type of epilepsy. Extensive clinical research is required for these herbs and formulations to prove their efficacy in the management of all the types of epilepsy. REFERENCES 1.
