Uses: Horse chestnuts and buckeyes (a similar but often smaller North American species of the same genus) somewhat resemble true chestnuts in appearance but are edible only after careful preparation. The wood of the horse chestnut is soft and has been used for paper pulp and carpentry, woodenware, and other similar purposes. A compound derived from horse chestnut, aesculin, is a pharmaceutical agent used as an astringent and anti-inflammatory.
There is an unproven belief that horse chestnut increases the strength and tone of the veins in particular, so horse chestnut extract is often used to treat phlebitis, varicose veins, and haemorrhoids.
