Rating (out of 5): 2

Chinese Sumac (Rhus chinensis) has a long history of use in traditional Chinese medicine (TCM) for various ailments, including the prevention and treatment of colds. In TCM, Chinese Sumac is valued for its astringent and antimicrobial properties, and is sometimes included in herbal formulations intended to clear heat, resolve toxicity, and treat symptoms such as sore throat and cough associated with colds. Historical records and classical materia medica texts document its use for these purposes, reflecting a tradition-based rationale for its application in cold prevention and management.

However, modern scientific studies specifically supporting the efficacy of Chinese Sumac for preventing or treating the common cold are limited. While some laboratory research has identified antimicrobial and antiviral constituents in Rhus chinensis (such as tannins and flavonoids), direct clinical evidence in the context of human respiratory infections is lacking. Therefore, the use of Chinese Sumac for colds is supported primarily by traditional practices and historical usage, with only limited preclinical scientific evidence and no robust clinical trials to validate its effectiveness for this condition.
