Triglochin palustre (Scientific name)

General poisoning notes:

Marsh arrow-grass (Triglochin palustre) is a native plant that is found sporadically across Canada in damp brackish or calcareous places. A cyanogenic glycoside, triglochinin, is found in the plant. This chemical becomes more abundant during times of moisture depletion within the plants. Occasional poisoning occurs with cattle and sheep in the lower Cariboo district of British Columbia (Majak et al. 1980, Looman et al. 1983).

Notes on Toxic plant chemicals:

A cyanogenic glycoside, triglochinin, is found in marsh arrow-grass. This chemical is also the main toxic component of seaside arrow-grass (Majak et al. 1980).

Notes on poisoning:

In all animals, symptoms of poisoning are similar to those of cyanide poisoning, including convulsions, nervousness, trembling, and recumbency, followed by death. The blood is bright red Looman et al. 1983).
