Cyanide Poisoning after Consuming a Large Amount of Gingko Nuts

Traditionally, the gingko nut is used for enhancing liver function, skin immunity, pulmonary function, and antitussive action in chronic asthma. However, when overused, it can induce central nervous system dysfunction, and the following symptoms can manifest themselves: vomiting, dizziness, convulsion, insomnia, and confusion. We experienced a case of suspected cyanide intoxication that was manifested by convulsion and metabolic dysfunction after consuming a large number of ginko nuts. We report that case, together with a review of the literature.
