General poisoning notes:
Five-hooked bassia
(Bassia hyssopifolia) is a naturalized herb found in southern parts of
western Canada. The plant is suspected of poisoning livestock. James et al.

above-ground parts of the plant.

Notes on poisoning:
In experimental
feeding of sheep, five-hooked bassia caused symptoms similar to poisoning by Kochia
scoparia. In addition to the symptoms listed, hemorrhaging on the rumen
surface and enlarged kidneys occurred. Calcium concentrations in the serum of
five sheep dropped from an average of 10.9 mg/mL to 3.6 mg/mL. Signs of
photosensitization were also noted in some of the sheep (James et al. 1976).
