In Greek medicine, the leaves and tendrils were recommended for topical application against headaches and fruit juice to treat diarrhea and liver disorders. The leaves are known to be astringent and were recommended in the 19th century for chronic diarrhea, dysentery and hemorrhages, hence the use of the leaf powder in bleeding from the uterus and nose. In folk medicine, the sap is known to be oral diuretic and useful against sores and ophthalmia. The ashes of the branches also enjoy a diuretic reputation. The leaf and tendril harvested at maturity are tonic, diuretic and venotonic.
Leclerc (20th century) recommends them in circulatory disorders of puberty, rosacea and varicose veins, but preference is given to red leaves, rich in tannins. Today in Europe, the leaf is popularly renowned for its astringent and homeostatic properties and its use in the treatment of diarrhea, bleeding, hemorrhoids, varicose veins and circulatory disorders of venous origin.
