What are the main medicinal uses of Digitalis purpurea?

The main medicinal uses of Digitalis purpurea are primarily for treating heart failure, hypertension, and cardiac arrhythmia, which are often symptoms of atrial fibrillation and supraventricular tachycardia.

The cardiac glycosides, particularly digoxin and digitoxin, found in this plant, act by inhibiting the sodium-potassium ATPase pump, leading to increased intracellular calcium, which enhances contractility in hypertrophic cardiomyopathy and reduces symptoms of angina pectoris and palpitations. Digitalis purpurea also contains flavonoids and phenylethanoid glycosides, which contribute to its anti-inflammatory and antioxidant properties, useful in managing asthma. The increased vagal tone caused by cardiac glycosides helps regulate heart rate, thereby alleviating cardiac insufficiency.

The plant's constituents have been used to treat various cardiovascular conditions, including atrial fibrillation and supraventricular tachycardia, by regulating heart rhythm and increasing cardiac output.

The following illustration give a summary of the main medicinal uses of Digitalis purpurea.

Circulatory System

Digitalis purpurea regulates heart rate by increasing the force of atrial contractions and slowing the ventricular rate through its glycoside compounds that inhibit the Na+/K+-ATPase pump, resulting in increased intracellular sodium and calcium, which in turn enhances myocardial contractility.

Improves cardiac output due to increased cardiac contractility, which is attributed to the increased intracellular calcium levels that result from the inhibition of the Na+/K+-ATPase pump by the glycosides. Enhances diastolic function by increasing the time available for diastolic filling due to the decreased heart rate and increased atrial contraction force. Reduces blood pressure by increasing peripheral vascular resistance due to the stimulation of alpha-adrenergic receptors and the inhibition of beta-adrenergic receptors, which results from the increased intracellular calcium levels.

Digitalis purpurea also increases cardiac contractility, stimulates atrial contraction, decreases stroke volume, improves vascular tone, and increases venous return through its vasoconstrictive and cardiotonic effects that are mediated by the glycosides and their influence on the Na+/K+-ATPase pump.

The most common side effects Digitalis purpurea gives people when used improperly are listed below, along with a brief explanation.

What are the precautions to take before using Digitalis purpurea medicinally?

The precautions to take before using Digitalis purpurea medicinally are contraindicated in pregnancy due to potential fetal harm, as Digitalis exerts direct effects on the fetus and also passes the placenta, and digitalis glycosides can cross the placental barrier.

Monitoring potassium levels is crucial since Digitalis purpurea acts on the heart by increasing the contractility and decreasing the conduction velocity, and hypokalemia can exacerbate the risk of arrhythmias. Digitalis purpurea should be avoided in renal failure, as this condition can lead to an accumulation of the drug and increased toxicity. The patient should watch for signs of overdose, such as nausea, vomiting, visual disturbances, and palpitations, as these can be indicative of digoxin toxicity.

Digitalis purpurea interacts with certain medications, including quinidine, verapamil, and amiodarone, and should be used with caution in the elderly due to decreased renal function and potential interactions, and it should not be used in patients with hypokalemia, and an ECG should be monitored for arrhythmias, and the exact dosage should be used according to the patient's needs, and consulting an expert before use is highly recommended.
