Specialty Definition: HORSE-CHESTNUT

Domain Definition
Noah Webster [Noun] A large nut,the fruit of a species of Aesculus; or the tree that produces it. The tree is much cultivated for shade.. Source: Webster's 1828 American Dictionary.
Aerospace Horse-chestnut is and introduced tree that is found in the southern parts of Ontario and Quebec. It has poisoned cattle, horses, and pigs, causing sickness and death (Reynard and Norton 1942, Muenscher 1975). Human poisoning has also occurred. Horse-chestnut fruits, leaves, and flowers contain the chemical aesculin. Young leaves and flowers are especially toxic to cattle (Reynard and Norton 1942). Children occasionally ingest the fruit but few authenticated cases of poisoning are found in the literature, although death has been reported (Lampe and McCann 1985). Aesculin is a saponin (7-hydroxycoumarin 6-glucoside) that yields aesculetin (6,7-dihydroxycoumarin) upon hydrolysis. Aesculin is related to hydrocoumarin found in spoiled sweet-clover hay (Cooper and Johnson 1984). LD-50 measurements from nut extracts were as follows (Williams and Olsen 1984): 1- 10.6 mg/g of body weight for chicks; and 2- 10.7 mg/g of body weight for hamsters. General symptoms of poisoning: 1- Humans and Cattle: a- death; b- depression; c- diarrhea; d- gastroenteritis; e- muscle twitching; f- paralysis; g- pupil dilation; h- restlessness; i- unconsciousness; j- vomiting; and k- weakness.

Common Expressions: HORSE-CHESTNUT

Expressions Definition
Common Horse-chestnut The Common Horse-chestnut (Aesculus hippocastanum) is a large deciduous tree, native to a small area in the mountains of the Balkans in southeast Europe, but widely cultivated throughout the temperate world. It grows to 35 m tall, with a domed crown of stout branches, on old trees the outer branches often pendulous with curled-up tips. The leaves are opposite and palmately compound, with 5-7 leaflets; each leaflet is 10-25 cm long, making the whole leaf up to 50 cm across, with a 20 cm petiole. The flowers are white with a small red spot; they are produced in spring in erect panicles 10-20 cm tall with about 20-50 flowers on each panicle. Usually only 1-5 fruit develop on each panicle; the fruit is a green, softly spiky capsule containing one (rarely two or three) nut-like seeds called horse chestnuts and also known as conkers. Each conker is 2-4 cm diameter, glossy nut-brown with a whitish scar at the base. (references)
