Zamia pumila
A Florida cycad with starch-bearing roots processed by Seminoles as food; raw plant toxic.
Zamia pumila, a cycad native to Florida, produces starch-rich roots traditionally processed by Seminole tribes as a food source after thorough detoxification. The plant contains the neurotoxic glycoside cycasin, which has been studied for its role in neurodegenerative conditions, alongside starch and tannins. Modern research focuses on its toxicology, particularly the mechanisms of cycasin-induced neurotoxicity.
Cycasin, a methylazoxymethanol glycoside, is hydrolyzed in the gut to the active aglycone, which causes DNA alkylation and oxidative stress, leading to neuronal damage. This compound inhibits protein synthesis and induces apoptosis in cerebellar Purkinje cells, mimicking aspects of amyotrophic lateral sclerosis (ALS) and other neurodegenerative disorders. Tannins may contribute to gastrointestinal irritation, while the starch component is safe only after thorough processing to remove toxins.
