Toxicity

Cycas micronesica, another Cycas, is linked with the human degenerative disease Lytico-Bodig disease, which is similar to amyotrophic lateral sclerosis (ALS) through a neurotoxin (BMAA) in the seeds (due to symbiosis with cyanobacteria), which were a traditional food source on Guam until the 1960s.
