Known in TCM as Hei Mu Er (黑木耳), this sweet, neutral herb enters the Lung, Stomach, Liver, Spleen, Kidney, and Large Intestine. Traditionally, it cools Blood and stops bleeding, most often applied for constipation, hemorrhoids, and blood stasis. Modern research has identified Auricularia polysaccharides (AAPs) among its active constituents.
Part used: Fruiting body (fungus)

Traditional Use
Primary Actions
- Cools Blood and stops bleeding … used for hemorrhoids, hematuria, uterine bleeding, and other mild bleeding patterns where an edible hemostatic is appropriate
- Nourishes Blood and gently dispels Blood stasis … commonly used in postpartum or traumatic recovery when deficiency and mild stasis coexist
- Moistens the Intestines and unblocks the bowels … addresses dry constipation, especially in the elderly or after illness
Secondary Actions
- Food-medicine support for vascular circulation … often incorporated into soups and stir-fries rather than used as a strong standalone decoction herb
- Provides gentle fluid and Yin support through diet therapy while remaining light enough for long-term culinary use
Classical References
- IMPORT NOTE: The source XLSX imported this entry as 'aruicularia' and the stub English name as 'Aruicularia'. The correct botanical spelling is Auricularia auricula-judae; the slug is retained unchanged for source continuity.
- FOOD-MEDICINE NOTE: Hei Mu Er (黑木耳, black wood ear) is not a root herb but the fruiting body of an edible fungus; it is widely used in Chinese diet therapy for Blood nourishment, gentle Blood movement, and bowel moistening.
- Materia medica and later food-therapy traditions distinguish Hei Mu Er from Bai Mu Er/Yin Er (white wood ear): the black fungus is used more for Blood and bowel indications, while the white fungus is used more for Lung and Stomach Yin nourishment.
