Ginkgo biloba, also known as ginkgo, is sweet and can be cooked and fried. It has the functions of eliminating phlegm, relieving cough, moistening lung and relieving asthma, but it can cause poisoning if eaten in large quantities. Ginkgo biloba contains hydrocyanic acid toxin, which is very toxic. The toxicity is reduced after heating, and it is easier to be poisoned when eaten raw. The general poisoning dose is 10-50 capsules, and the poisoning symptoms appear at 1- 12 hours after eating ginkgo biloba. In order to prevent ginkgo poisoning, it is not advisable to eat more ginkgo, which is more common in children. If you are an adult, cooking soup, even if you eat 50 pills, should be no problem.
