The Horse Chestnut tree originated in the Balkans but is thought to have been imported to Europe by the ships of the East India Company, hence its name. It is a large tree (about 25 m high) with coppery bark and dark green foliage. Its leaves are harvested in summer, and in autumn its bark and fruit, the chestnuts, are harvested.
The Chestnut bud has traditionally the status of venous tonic in gemmo. It is often recommended to people with a feeling of heavy legs.
