Medicinal Benefits of Horse Chestnut

Botanical Profile

  • Hippocastanaceae family; Horse chestnuts exist in nature as both a tree and a shrub

  • 15 recognized species of horse chestnut. The European horse chestnut is believed to have originated in the Balkan region of eastern Europe but is now grown in every country in the Northern Hemisphere.

  • Grows to 118 ft. tall, with a domed crown of stout branches; The leaves are opposite and palmate with 5–7 leaflets

  • The flowers are usually white with a small red spot; flowers are produced in spring

  • 1–5 fruit develop on each flower cluster

  • The fruit's shell is a green, spiky capsule containing one (rarely two or three) nut-like seeds called conkers or horse-chestnuts.

  • The sticky sap on horse chestnut buds protects them from frost damage and insects.

  • Horse chestnut conkers are slightly poisonous to most animals, causing sickness if eaten.

Historical Background

  • A famous specimen of the horse-chestnut was the Anne Frank Tree in the centre of Amsterdam, which she mentioned in her diary and which survived until August 2010, when a heavy wind blew it over. Eleven young specimens, sprouted from seeds from this tree, were transported to the United States.

  • After a long quarantine in Indianapolis, each tree was shipped off to a new home at a notable museum or institution in the United States, including the 9/11 Memorial Park.

  • An ancient superstition of carrying a horse chestnut seed around in one’s pocket to prevent or cure arthritis still exists in some countries

She felt a little betrayed and sad, but presently a moving object came into sight. It was a huge horse-chestnut tree in full bloom bound for the Champs Elysees, strapped now into a long truck and simply shaking with laughter - like a lovely person in an undignified position yet confident none the less of being lovely. Looking at it with fascination, Rosemary identified herself with it, and laughed cheerfully with it, and everything all at once seemed gorgeous.
