Not edible.
Black fungus soaked for a long time, there will be toxins produced, can not be eaten. Black fungus soaked in moderation, if soaked more than one, refrigerator for 24 hours, more than 24 hours, no matter whether it is spoiled or not should be thrown away. The fungus soaked for a long time will breed bacteria, so that the fungus appeared to deteriorate and tasteless, but also produce toxins, endangering the health of the body, and the fungus soaked for a long time will be relatively soft, and its edible taste will also be reduced, so the fungus is not edible.
After a long time of soaking, if the storage environment is not suitable, the bacteria will reproduce a lot, there is a class of bacteria called Pseudomonas aeruginosa will be metabolized to produce a kind of toxin called "rice fermentation bacterial acid". This toxin is very toxic, can cause liver and kidney damage, and cause systemic organ failure, high lethality.
This toxin is usually found in spoiled fungus and fungus, and this toxin is very resistant to high temperatures, even if the fungus and fungus after heating or stewing, the toxin can not be decomposed, at the same time this toxin is not easy to wash off, and there is no effective medication after ingestion, can be said to be very dangerous. Pseudomonas syringae likes high temperatures, such as 25-35 degrees Celsius environment, so the consumption of fungus poisoning often occurs in the summer.

1, hypoglycemic effect Mullein polysaccharides on tetracycline diabetic mice hyperglycemia has a preventive and curative effect, so that the experimental mice glucose tolerance and tolerance curve has been significantly improved, but also reduce the amount of drinking water in diabetic mice.
2, lipid-lowering effect Mucuna pruriens polysaccharides can significantly reduce serum free cholesterol, cholesterol lipids, triacylglycerol, 9-lipoprotein content of hyperlipidemia rats, reduce high cholesterol-induced hypercholesterolemia in mice.
3, inhibit platelet aggregation Adenosine and several related water-soluble oligomers, can significantly extend the concentration of thromboplastin time inhibition of platelet aggregation, proving that adenosine is a potent platelet aggregation inhibitor. It can be absorbed intact by the small intestine, but the active does not affect the synthesis of coagulant oxytetracycline from [14C]arachidonic acid, showing that the substance does not inhibit platelet cyclooxygenase.
4, anti-thrombosis Fungus polysaccharide can obviously prolong the formation time of rabbit specific thrombus and fibrin thrombus, shorten the length of thrombus, reduce the wet and dry weight of thrombus, reduce the number of platelets, reduce the platelet adhesion rate and blood viscosity, and can obviously shorten the time of guinea-pig euglobulin dissolution, reduce the content of fibrinogen in the paddles of the blood, and elevate the fibrinolytic enzyme activity, which is an obvious antithrombotic effect.
