Digitalis lanata that is extracted from "Digitalis lanata". It is used to treat some heart conditions such as atrial fibrillation. It slows atrioventricular conduction so that the heartbeat slows down and slightly increases contraction power (positive inotropic effect). Because of the improved circulation in congestive heart failure caused by fast atrial fibrillation, the kidneys can function better, which stimulates the flow of urine, which lowers the volume of the blood and lessens the load on the heart. This is the effect that was first described when the plant was discovered as a medicine (Withering 1785). Digitalin was not discovered until the mid-19th
