Aesculus

 

a genus of tree and, less frequently, shrub of the family Hippocastanaceae. The leaves, which are opposite and digitately compound, usually have five to nine leaflets. The irregular flowers are gathered in erect paniculate inflorescences. There are approximately 15 species (according to other data, 25), growing in Europe (the Balkan Peninsula), Asia (the Himalayas, China, and Japan), and North America. One of the most common is the horse chestnut (Aesculus hippocastanum), often grown in gardens and parks. The tree measures up to 30 m tall; its trunk is up to 2 m in diameter. The crown is broad and full. An extract of the roots is used in medications for hemorrhoids, dilation of the veins, thrombophlebitis, atherosclerosis, and other conditions.
