    Cycad palms produce three toxins: cycasin, beta-methylamino-L-alanine, and an unidentified toxin.3-6 Cycasin, which is converted to its aglycone, methylazoxymethanol, may cause centrilobular and midzonal coagulative hepatic necrosis and gastrointestinal irritation. In addition, cycasin is carcinogenic, mutagenic, and teratogenic.3,5,6 Beta-methylam...

    In one study, the most common signs in dogs ingesting cycad plants were gastrointestinal, hepatic, and neurologic.10 In cases reported to the American Society for the Prevention of Cruelty to Animals (ASPCA) Animal Poison Control Center and recorded in the AnTox database between 1988 and 1998, the most common signs of cycad toxicosis in dogs were v...

    Gastrointestinal abnormalities in dogs with cycad poisoning include hemorrhage and mucosal necrosis. Histologic abnormalities in the livers of these dogs include cirrhosis with marked focal centrilobular and midzonal coagulation necrosis.2

    Cycad toxicosis is diagnosed based on a history of known exposure (e.g. observed ingestion, identification of chewed plants, identification of plant material in vomitus) and compatible clinical signs. Although cycasin and beta-methylamino-L-alanine can be found in the livers of animals that ingest cycad palms, no diagnostic laboratories routinely t...

    Treatment of cycad toxicosis is symptomatic and supportive. No antidote for any cycad toxin is available.2 Measure hepatic enzyme activities and bilirubin concentrations on presentation, and monitor these values daily for 72 hours. If elevations are found, monitor the parameters until they return to normal. Administer supportive therapy as needed. ...
