Overview

Horse chestnut is a tree native to the Balkan Peninsula. The seeds, leaves, bark, and flowers have been used for centuries to treat a variety of health problems. The most common use of horse chestnut extract is for chronic venous insufficiency (CVI), a condition in which the veins in the legs are not able to efficiently pump blood back to the heart. This can lead to symptoms such as varicose veins, swelling, and pain in the legs. The active compound in horse chestnut is aescin, which is believed to work by strengthening the walls of the veins and reducing inflammation. Horse chestnut is also used to treat hemorrhoids and other conditions related to poor circulation.
