1, boiled fungus should not be eaten overnight, if left for too long, it may be contaminated by certain bacteria.

2, here and now, the toxins produced by the fungus such as nausea, vomiting, abdominal pain, diarrhea, etc. can cause poisoning. It can happen, and in severe cases can lead to liver failure. But it tastes good, and contains a lot of nutrients, can smooth the stomach and intestines, lower blood pressure, improve cardiovascular function, so fresh edible fungus is OK.
