The main virtue of horse chestnut is its venotonic, basqueconstrictive and anti-inflammatory actions. The seeds contain flavonoids (esculin), saponosides (escin), tannins and minerals . The leaves contain coumarin heterosides, flavonoids and phytosterols, also present in the bark, which is especially rich in allantoin and tannins.
Aescin and esculin are the substances that give it the ability to promote peripheral blood flow and prevent stagnation . Together with the ginkgo, the red vine and the butcher's broom, it is considered one of the best herbal remedies to treat the different symptoms associated with problems of weakness or venous insufficiency.

• Tingling and cramps, feeling of numbness in feet, legs (especially calves) and hands.
• Swollen veins in the legs or phlebitis, causing heaviness and burning. Horse chestnut reduces inflammation and helps burn away.
• Hemorrhoids. It prevents their appearance and helps to combat them, although it can be associated with a proper diet.
