Introduction
Can ginkgo tree fruit be eaten? The fruit of the ginkgo tree is known as ginkgo nut (bai guo). Mature ginkgo nuts are edible and typically ripen in September and October. If the outer skin turns yellow and feels soft, the nut is ready for consumption. Ginkgo nuts contain ginkgolic acid and ginkgo phenol, which experiments have shown to possess antibacterial and bactericidal properties, making them useful in treating respiratory infectious diseases.

Generally speaking, the fruit of the ginkgo tree refers to ginkgo nuts (also known as "white nuts"). Whether ginkgo nuts are edible depends on whether they are raw or cooked. If any discomfort occurs, it is recommended to seek medical attention promptly. The details are as follows:

1. Not edible (raw)

The outer pulp of ginkgo nuts contains certain amounts of toxic substances such as hydrogen cyanide and ginkgolic acid. Consuming raw ginkgo nuts directly may lead to poisoning symptoms, including nausea and vomiting. In severe cases, it could even be life-threatening. Therefore, they should not be eaten in this form.

2. Edible (cooked)

However, if ginkgo nuts have been properly processed—such as having their skins removed and being thoroughly cooked—these methods can effectively reduce toxin levels. When prepared this way, moderate consumption is safe and acceptable.

In summary, ginkgo fruits should not be consumed raw. However, the inner kernel (the white nut) can be safely eaten after appropriate processing. Before consumption, it is essential to understand the correct preparation methods and adhere to the principle of moderation to ensure safety.
