Extended information:

Deadly mechanism: Although the roots of cassava are rich in starch, all parts of the plant, including roots, stems, and leaves, contain toxic substances, and fresh roots are toxic larger. Therefore, care must be taken when consuming cassava roots.

The toxic substance contained in cassava is linolein. If you ingest raw or undercooked cassava or drink its soup, it may cause poisoning. The reason is that linamarin or linamarinase produces free hydrocyanic acid after hydrolysis by gastric acid, which poisons the human body. If a person eats 150 to 300 grams of raw cassava, it can cause poisoning or even death.

Detoxification method: To prevent cassava poisoning, peel the cassava before eating it, and soak the potato flesh in water to dissolve the cyanogenic glycosides.
