Is the fresh fungus poisonous?
Fresh fungus contains a light-sensitive substance called porphyrin. After entering the body, it will distribute to the human epidermal cells with the blood circulation. If you are exposed to the sun at this time, you may cause solar dermatitis, rash and other diseases, if you eat too much can cause respiratory tract allergy and respiratory difficulties occur.
This kind of material is insoluble in water, although the fresh edible fungus does not reduce its toxicity even though it has been washed or soaked in water. So do not eat fresh fungus.
Dried fungus is a sun-treated product. In the process of exposure, porphyrins can be decomposed spontaneously, so dried fungus is non-toxic. Before the edible fungus is eaten, the water-flavoured fungus formed after immersing in water is also non-toxic and can be eaten with confidence.

Why shouldn't eat fresh fungus
Because in the fresh fungus contains light-sensitive substances of a porphyrin, after the humans eat it, the sun can cause skin itching, edema, and can cause severe skin necrosis. Therefore, it is generally considered that it is best not to eat fresh fungus and select dried fungus.
The sun-dried fungus, which is exposed to sun exposure, will decompose most of the porphyrins during exposure, and before eating, the dried fungus will be soaked in water. The remaining porphyrins will dissolve in the water and the water will dry out. Wood can be eaten safely. It should be noted that more water should be changed when soaking dried fungus.
