For centuries, motherwort has been used as a medicinal plant to treat heart diseases. The herb has diuretic properties and may inhibit artery calcification formation.
It is also used as a remedy for milder forms of Graves’ disease (an autoimmune disease that affects the thyroid) and for hypertension.
Motherwort is considered more effective in lowering blood pressure than valerian (Valeriana officinalis), and the plant’s high content of vitamins A and C also add to its beneficial effect.
Extracts of the plant have been used as a treatment for mild and chronic cardiac and vascular diseases, especially in the elderly.
It has also been used for rapid heart rate, some other minor irregularities in the heart’s rhythm and to reduce the risk of blood clots (thrombosis).
Many herbalists consider the plant particularly effective in treating palpitations (tachycardia), especially when this is due to anxiety. The herb has been used traditionally for most heart-related problems associated with anxiety, tension, and stress.
The German Commission E states that motherwort can be used for irregularities related to the heart caused by overstimulation of the thyroid gland (Hyperthyroidism/thyrotoxicosis).
