Sago raw starch suspension in water is then collected in a settling container. The sago cycad, "Cycas revoluta", is a slow-growing wild or ornamental plant. Its common names "sago palm" and "king sago palm" are misnomers as cycads are not palms. Processed starch known as sago is made from this and other cycads. It is a less-common food source for some peoples of the Pacific and Indian Oceans.- Unlike "metroxylon" palms (discussed above), cycads are highly poisonous: most parts of the plant contain the neurotoxins cycasin and BMAA. Consumption of cycad seeds has been implicated in the outbreak of Parkinson's disease-like
Sago of raw sago are imported each year into Malaysia to support the keropok lekor industry. In 1805, two captured crew members of the shipwrecked schooner "Betsey" were kept alive until their escape from an undetermined island on a diet of sago. Any starch can be pearled by heating and stirring small aggregates of moist starch, producing partly gelatinized dry kernels which swell but remain intact on boiling. Pearl sago closely resembles pearl tapioca. Both are typically small (about 2 mm diameter) dry, opaque balls. Both may be white (if very pure) or colored naturally grey, brown or black, or artificially
