4. Don't eat tremella overnight to prevent poisoning.
Both bag-cultured tremella and open-air basswood-cultivated tremella contain more nitrate, which will be reduced to nitrite under the decomposition of bacteria if it is left for a long time after cooking. If you drink tremella soup overnight, nitrous acid will enter the blood circulation, which will make normal hemoglobin in the human body oxidized to methemoglobin, thus losing its oxygen-carrying ability, causing poisoning and a series of enterogenous cyanosis symptoms. So don't drink tremella soup overnight.
