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.

Modern Research

Active Compounds

  • Auricularia polysaccharides (AAPs) — major bioactive heteropolysaccharides with immunomodulatory and metabolic activity
  • Beta-glucans and dietary fiber
  • Melanin pigments
  • Phenolic compounds
  • Adenosine and related nucleosides

Studied Effects

  • Hypoglycemic and antiglycation — degraded Auricularia polysaccharides inhibited advanced glycation end-product formation and improved glucose-handling models under high-sugar stress (PMID 32450039)
  • Wound-healing and anti-inflammatory — Auricularia polysaccharides accelerated fibroblast migration and re-epithelialization in skin-repair models (PMID 33806146)
  • Functional-food antioxidant and immunomodulatory activity — review literature identifies polysaccharides as the main contributors to antioxidant, lipid-lowering, and immune-regulating effects (PMID 33543932)
