Lamb's-quarters
General poisoning notes:
Lamb's-quarters (Chenopodium
album) is a naturalized annual herb found in disturbed soils across Canada.
This plant can cause sickness and death in livestock if large quantities are
ingested. The plants can accumulate both nitrates and soluble oxalates. Cattle
and sheep have been poisoned. Humans who consume large quantities of the plant
and are subsequently exposed to sunlight suffer photosensitization (Whitehead
and Moxon 1952, Cooper and Johnson 1984).
