Cassava is also called sweet potato. It has great economic value and can be made into starch. Some areas in southern China have the habit of eating cassava, but cassava can't be eaten raw. Because cassava is a plant containing cyanosides, it can release hydrocyanic acid after being hydrolyzed by enzymes or acids. Hydrocyanic acid is protoplasm toxin. After being absorbed, cyanogen ion will combine with iron in cytochrome oxidase in human body, which will make respiratory enzyme inactive, and oxygen can not be used by cells and tissues, resulting in hypoxia and suffocation. Poisoning symptoms usually appear within one to several hours after eating. First, nausea, vomiting, abdominal pain and diarrhea, then dizziness, irritability, convulsions and coma, which can lead to death in severe cases. So cassava can't be eaten raw. It must be soaked in water for a long time or cooked before eating. Hehe, I hope it works for you. Good luck, happy every day, happy New Year and all the best.
