Sweet clover is an herb. The flowering branches and leaves are used to make medicine. Be careful not to confuse sweet clover with red clover.
Sweet clover is used to increase the loss of water from the body through the urine (as a diuretic). It is also used for varicose veins and to relieve symptoms of poor blood circulation (chronic venous insufficiency) including leg pain and heaviness, night cramps, itchiness, and fluid retention (edema).
Sweet clover is sometimes used along with regular medicines for treatment of blood clots in the veins.
Other uses include treatment of hemorrhoids and blockage of the lymphatic system. The lymphatic system drains fluid from tissues.
Some people apply sweet clover directly to the skin for bruises.
