Horseradish

General poisoning notes:

Horseradish (Armoracia rusticana) is a cultivated plant that can persist after cultivation. The plant contains glucosinolates, which can cause toxicity in livestock. Irritation of the mucous membranes can occur in humans who grind the roots to produce horseradish condiment. See the notes under Brassica oleracea for more information on these chemicals. Under normal circumstances horseradish is safe.
