Red vine is the leaf of the common grapevine, Vitis vinifera. The French name is vigne rouge. Red-leaved types are picked in autumn, when the leaves turn deep red.
It is sold mainly for tired, heavy, swollen legs. European folk use also pointed it at varicose veins and piles. Long use in tradition is not proof that it works, and it is not proof that it is safe.
Here is the short verdict. A standard leaf extract has reduced leg swelling in several human trials. The trials are few, fairly short, and many were paid for by the maker.
The main idea is that red vine leaf helps leaky leg veins hold fluid better.
In cell and animal studies, its flavonoids appear to tighten the walls of small blood vessels. They also seem to calm inflammation in those vessels. Less fluid then leaks into the tissue of the lower leg.
In people, the tested extract has lowered the measured volume of swollen lower legs. It does not remove varicose veins. Whether it slows vein disease over years is not known.
The form with human evidence behind it is the standard dry leaf extract, taken by mouth.
- Capsules or tablets of red vine leaf extract. - Dried leaf for tea or a leg soak. - Tincture, the leaf steeped in alcohol.
You will also find these on the shelf.
- Gels, sprays and creams for the legs. - Blends with horse chestnut or butcher's broom.
Skin gels can feel cooling and pleasant. Cooling is not the same as treating.
The trials used capsules, not gels, teas or blends. Blended products also make it hard to know what, if anything, is acting.
European folk healers used red vine leaf for heavy legs and visible veins. In France it was known as vigne rouge and brewed as a tea. Leaf baths and compresses were laid on tired legs and on piles.
Grape leaves were also eaten and used for bleeding and loose bowels. Modern interest began in Germany, where a leaf extract was made for vein complaints.
These older uses were handed down by habit, not tested the way medicines are tested now.
Stop and see a doctor if you get a rash, itching or stomach upset that does not settle.
Get urgent care for swelling of the face, lips or throat, or for trouble breathing.
See a doctor the same day for one leg that is suddenly swollen, hot, red or painful. Book an appointment for skin changes, weeping or an open sore near the ankle, for bleeding from the back passage, or for breathlessness with swollen legs.
In the EU and UK, red vine leaf is sold as a food supplement or a traditional herbal product. The European Medicines Agency has published a herbal monograph on the leaf. In the United States it is an ordinary dietary supplement and is not approved to treat any disease.
