General Symptoms of Poisoning:

Notes on Poisoning:

Ingesting material containing calcium oxalate raphide crystals causes irritation of the soft mouth parts and perhaps the throat of humans and animals. Swelling of tissues causes pain and a burning sensation that slowly subsides. Cool liquids or analgesics may be indicated. The insoluble oxalates do not cause systemic poisoning (Lampe and McCann 1985).
