Herbal extracts: the future treatment option for drug-resistant epilepsy.

Epilepsy is a neurological disorder characterised by two or more unprovoked seizures. The high prevalence and incidence of epilepsy globally, especially in Asia, has remained a big concern over the course of centuries. Patients are usually prescribed the already known anti-epileptic drugs, but even after going through three different generations of anti-epileptic drugs, some people still suffer from drug-resistant form of epilepsy. These patients are usually prescribed a higher dose of anti-epileptic drugs, which results in more adverse effects. That is why new treatment options, like herbal extracts, should be explored for patients who do not respond to the classic anti-epileptic drugs. The current narrative review was planned to explore if herbal extracts can be the future for the treatment of drug-resistant epilepsy.

A flavonoid driven phyto-pharmacological effects of Capparis decidua Edgew. in rodents.

This study elicits the underlying mechanism(s) of Capparis decidua when used for different gut disorders. HPLC chromatogram of C. decidua extract (CD.Cr) and its respective fractions showed a variety of phytochemicals of which, kaempferol being in a high proportion. In mice, CD.Cr at doses of 70 and 150 mg/kg enhanced the wet feces output to 33 and 44% respectively as compared to carbachol (47.6%), while doses of 500 and 700 mg/kg, presented 41 and 70% safety against castor oil-driven diarrhea, respectively. Its flavonoid constituent, kaempferol at doses of (50 and 100 mg/kg) produced 51.7 and 82% safety when compared to nifedipine which provided 95% safety at dose of 40 mg/kg against castor oil-driven diarrhea like loperamide. In isolated jejunum preparations, C. decidua extract and its respective fractions (except pet-ether) produced atropine-sensitive inhibitory effects, whereas kaempferol and nifedipine showed atropine insensitive effects. Against high K+-induced contractions, C. decidua's fractions and kaempferol both exhibited a concentration-related non-specific inhibition while displacing the Ca++ -CRCs to right-ward with suppression in maximal response like nifedipine. In isolated rat ileal preparations, CD.Cr and respective fractions elicited atropine-sensitive gut excitatory responses. In summary, this article reports C. decidua's laxative effect through cholinergic receptor activation as well as its antidiarrheal effects, where its flavonoid constituent kaempferol produces Ca++ antagonist like activity, thus justifying C. decidua folk use in constipation and diarrhea.
