Horse chestnut has been used in alternative medicine and is likely effective in treating some symptoms of chronic venous insufficiency (decreased blood flow return from the feet and legs back to the heart). These symptoms include leg pain or tenderness, varicose veins, itching or swelling in the legs, and fluid retention (puffy or swollen ankles or feet).

Other uses not proven with research have included fever, cough, diarrhea, hemorrhoids, enlarged prostate, menstrual cramps, and swelling caused by arthritis, sprains, or bone fractures.
