木薯品種有甜木薯(Manihot
esculenta )苦木薯(Manihot utilissima)
兩種，甜木薯種的塊根含較低的氰酸，表皮呈淡青色；苦木薯 的塊根含多量的氰酸，表皮呈褐色，兩者不難區別。塊根又以皮層
含氫氰酸最高，因此，木薯要先刮去外皮，煮熟後才能食用。木薯中毒系由其所含亞麻苦甙
(linamarin) 及亞麻苦苷酶
(linamarase)
水解後析出游離的氫氰酸(hydrocyanic acid）所
致。塊根未煮熟或氰酸(cyanic
acid)未完全分解前就拿來食用，內含的毒素會轉化為氰化氫
(hydrogen cyanide)。
中毒症状：輕者噁心、嘔吐、下痢、昏眩；嚴重者呼吸衰竭而死亡。還可引起甲狀腺腫，並會傷
害視神經和運動神經等。[1]
