Digitalis ( Digitalis purpurea ) contains cardiac glycosides like digitoxin,digoxin,gitoxin,gitalin etc. These gycosides have a positive Ionotropic and Chronotropic effect on the heart ie they increase the force and rate of contraction of heart which is one of the reason it can be used in heart failure however its use is not recommended as digitalis causes adverse effects like arrhythmias, hyperkalemia etc.
