Notes
The fleshy outer testa of the seeds contains ginkgo acid, ginkgo alcohol and ginkgo phenol, which are toxic.
Ginkgo contains slightly toxic substances: hydrocyanic acid, ginkgo acid, hydrogenated ginkgo acid, hydrogenated ginkgo acid, ginkgo phenol, and ginkgo alcohol. Therefore, you should pay attention to how you eat ginkgo when eating it.
If cooked and eaten, ginkgo acid and ginkgo acid can be decomposed, and hydrocyanic acid has a low boiling point and is easy to volatilize and remove, so the toxicity of cooked ginkgo is less. In order to prevent ginkgo poisoning, cooked food and eating less are the fundamental methods. The medical community believes that raw ginkgo should be limited to about 10 pills a day. Excessive consumption can cause symptoms such as abdominal pain, fever, vomiting, and convulsions.
Some people like to drink ginkgo leaves soaked in water, which is dangerous. Ginkgo leaves contain toxic ingredients. Excessive dosage or prolonged use can harm heart health.
