Horse chestnut is the name given to Aesculus hippocastanum. This is a plant noted for its benefits to vascular health. It has been used historically to treat and protect blood vessels, particularly in the legs, and it also helps reduce ankle swelling.
Horse chestnut is taken for a wide variety of vascular problems and venous diseases. Examples include varicose veins, haemorrhoids and leg ulcers. The seeds and root are used as well for decongestive purposes.
Powdered into a compound, they are said to clear up congestion in the sinuses and chest. You can buy horse chestnut seed extract in capsule form to be taken as a supplement to promote overall health. These health supplements are in tablet form and are widely available without a prescription.
