Black Fungus (Auricularia auricula-judae or Auricularia polytricha), often known as Wood Ear mushroom, is a staple in Traditional Chinese Medicine and East Asian cuisine. With its soft, ear-like shape and deep black sheen, it may appear humble—but its medicine is profound.
Black Fungus is traditionally valued for nourishing the blood, improving circulation, and restoring moisture to tissues that have become dry, stagnant, or depleted. It is a mushroom of subtle correction—helping the body regain flow without force.
