Scientific Summary
Galla Chinensis is a dried, resinous secretion harvested from the bark of the plant Rhus chinensis. It is traditionally used to support the immune system, ease cold and influenza symptoms, treat chronic diarrhea and edema, and has been employed as a cardiotonic and for abnormal uterine bleeding. Though generally considered safe when used as directed, it can cause stomach upset in some people and should be avoided by pregnant or breastfeeding women, and by those taking anticoagulants or other medications without first consulting a healthcare professional.
