Horse Chestnut
Horse Chestnut is used to improve circulation, reduce varicose veins, and alleviate symptoms of chronic venous insufficiency.
Horse Chestnut (Aesculus hippocastanum) is a tree native to Europe whose seeds have traditionally been used to support vein and circulatory health, particularly in cases of varicose veins and chronic venous insufficiency.
The active compound, aescin, may strengthen blood vessel walls, reduce swelling, and improve circulation. It is typically used in standardized extract form to ensure safety and efficacy.
Horse chestnut is commonly taken for leg swelling, vein discomfort, and vascular tone. While supported by several clinical trials, raw seeds or unprocessed forms should be avoided due to toxicity.
