Notes on Poisonous plant parts:

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).

Toxic parts:

flowers
leaves
mature fruit

Notes on Toxic plant chemicals:

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):

10.6 mg/g of body weight for chicks

10.7 mg/g of body weight for hamsters.

Toxic plant chemicals:

aesculin
