Lack of co-ordination, diarrhoea, convulsions and coma. Death is usually caused by respiratory failure.
Notes:
Although box is usually grown as a garden plant poisoning has
been reported in horses. This has usually come about because
the horse has gained access to a garden containing box or box
clippings have been left where they can be eaten. However in
normal circumstances horses are reluctant to eat box as it has
a nasty odour when bitten.
