Uses

Young curled-up fronds of C. riuminiana are edible and can be cooked as vegetables. The ripe seeds are poisonous, but they can be crushed and soaked in water several times to remove the toxins before being dried and processed into a flour-like substance used for making small cakes or gruels.[4]
