However, through research and literature search, it was found that the assertion that "fresh white fungus is toxic and contains porphyrins, which can cause solar dermatitis" lacks scientific basis. So far, no research literature and related tests have been found to contain porphyrin in Tremella fuciformis, and there have been no reports of solar dermatitis caused by the use of fresh Tremella.
