A medicinal preparation made from leaves or other parts of plants of the genus Digitalis (chiefly D. purpurea and D. lanata), and used in the treatment of certain types of heart disease.The cardiac glycosides contained in digitalis have two principal effects on the heart: they increase the force of contraction and slow the conduction of the cardiac impulse, esp. through the atrioventricular node. They are thus most useful in the treatment of congestive heart failure and tachycardia of atrial origin.Digitalis is sometimes used as a general term for these glycosides, esp. digoxin and digitoxin, which are now preferred for therapeutic use.
