Generally speaking, white wood ear and silver ear are actually the same ingredient; there is no effect that white wood ear possesses that silver ear does not. Although their names differ, their nature is identical, and there is no difference in their functions. Detailed analysis is as follows:

White wood ear and silver ear are merely different names for the same type of fungus. Their nutritional components and medicinal values are completely identical. Both contain polysaccharides, amino acids, and other substances, and have the same nourishing effects.
