Chinese gallnut

Ingredient Profile

Chinese Name五倍子
PinyinWu Bei Zi

Modern Research Perspective

Chinese Gallnut contains tannins, gallic acid, ellagitannins, and other polyphenols. Cell and animal studies have examined antimicrobial, antioxidant, hemostatic, gastrointestinal, and tissue-repair pathways, but evidence remains preclinical.

Human clinical evidence for a standardized single material is limited. Gastrointestinal irritation, nutrient binding, allergy, interactions, dose, and long-term safety require evaluation.

Traditional Function

Chinese Gallnut is traditionally sour, salty, and cold. It is used to astringe leakage, stop bleeding, reduce diarrhea, and clear selected heat-related conditions. Its tannin-rich nature requires appropriate pattern and dose.
