Butanol extracts (10 ug/ml) Butanol extracts (20 ug/ml) Control Results: Effect of cardamom extracts (Butanol) on 3T3 cell line Original recording graphs showing the same duration (100 msec) of the opening of the channels in B1 and B2 when compared to controls. However B2 increases outward rectifying potassium currents

Results: Methonolic NicotinumTobacom Extract (0.5mg/ml) Control NA Currents were normalized by cell capacitance (pA/pF) Methonolic Extract was tested on hippocampal cultured neurons. We found that it blocks delayed rectified Potassium currents
Na currents 2 Results CentellaAsiatica Extract (0.5mg/ml)On K+ and Na+ Currents CA Control Asiaticoside, an active constituent in methanol and ethylacetate extracts of C. asiatica, has anxiolytic activity. The extracts of C. asiatica, except Aqueous extract, possess anticonvulsant and neuroprotective activity and thus can be used for effective management in treatment of epileptic seizures. Methonolic Extract was tested on hippocampal cultured neurons. We found that it does not effect delayed rectified Potassium currents CA Control Control Control CA Na currents
Results CentellaAsiatica Extract (0.5mg/ml) On Sodium Currents Control CA Wash Methonolic Extract was tested on hippocampal cultured neurons. We found that it reduces Sodium currents. This is in consistent with the previous reported studies by Visweswari et al., 2011. This medicinal herb used as an anticonvulsant and for enhanced memory. The most important ingredients in methonolic extract is Asiaticoside which has an anxiolytic activity.
