    SWEET CLOVER Overview Information

    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.

    How does it work?

    Sweet clover contains ingredients that can thin the blood and help wounds heal.

    SWEET CLOVER Uses & Effectiveness What is this?

    Possibly Effective for:

    • Problems with circulation including leg cramps and swelling.
    • Varicose veins.

    Insufficient Evidence for:

    • Water retention (edema).
    • Hemorrhoids.
    • Bruises, when applied to the skin.
    • Other conditions.
    More evidence is needed to rate the effectiveness of sweet clover for these uses.

    SWEET CLOVER Side Effects & Safety

    Sweet clover seems to be safe for most people when used appropriately. But, it can cause liver damage and bleeding problems when used in large amounts.

    Special Precautions & Warnings:

    Pregnancy and breast-feeding: Not enough is known about the use of sweet clover during pregnancy and breast-feeding. Even though one small study found no harmful effects when used during the last 6 months of pregnancy, stay on the safe side and avoid use until more is known.

    Liver disease: There is some concern that sweet clover might make liver disease worse. If you have liver problems, get medical advice before starting sweet clover. Also, be sure to have liver function tests done.

    Surgery: Sweet clover might slow blood clotting. Some physicians worry that it might increase bleeding during or after surgery. Stop using sweet clover at least 2 weeks before a scheduled surgery.

    The following doses have been studied in scientific research:


    • For poor circulation (chronic venous insufficiency): 2-3 cups of sweet clover tea daily. A cup is made by steeping 1-2 teaspoons finely chopped sweet clover in 150 mL boiling water for 5-10 minutes and then straining. If you use sweet clover, be sure to have liver tests done, especially if you have a liver disease or existing liver damage.
