Introduction
Ginkgo seeds contain toxic substances that can irritate the gastrointestinal mucosa and cause poisoning. Cooking at high temperatures can destroy these toxins. If the seeds are consumed without prolonged storage and show no signs of spoilage, eating a large amount generally will not lead to poisoning. However, if they have been stored for a long time or improperly stored, leading to spoilage, consumption may result in poisoning.
In general, cooked ginkgo nuts that have not spoiled are unlikely to cause poisoning even if consumed in large amounts; however, if the nuts have spoiled, poisoning may occur. The specific analysis is as follows:
1. No poisoning
Ginkgo nuts contain toxic substances such as ginkgolic acid and hydrogen cyanide, which can irritate the gastrointestinal mucosa and lead to symptoms of poisoning when ingested. However, thorough cooking destroys these toxic components through high temperature. If the cooked ginkgo nuts have been properly stored for a short period without spoilage, eating larger quantities generally will not result in poisoning.
2. Poisoning may occur
If cooked ginkgo nuts are stored for a prolonged period under improper conditions and become spoiled, they may harbor significant amounts of bacteria or other harmful substances. Consuming spoiled ginkgo nuts, especially in large quantities, can irritate the gastrointestinal lining and lead to poisoning, manifesting as nausea, vomiting, and similar symptoms.
If poisoning occurs, immediate measures such as inducing vomiting should be taken to reduce absorption of the toxic substances in the gastrointestinal tract. In severe cases, prompt medical attention is required, and treatments such as gastric lavage or catharsis may be necessary.
