Coptis chinensis, also known as Huang Lian, is a traditional Chinese medicinal herb primarily used for its bitter and "heat-clearing" properties. In Traditional Chinese Medicine (TCM), it is often prescribed to clear heat and dry dampness, addressing conditions characterized by "damp-heat" such as gastrointestinal issues, infections, and certain skin conditions. Its use for sinus congestion or sinusitis is based mainly on TCM theory, where sinus congestion may be considered a manifestation of "damp-heat" or "toxic heat" in the upper respiratory tract. While Coptis chinensis is sometimes included in multi-herb formulas intended for respiratory complaints, its direct role is to reduce heat and inflammation rather than to act as a decongestant in the Western medical sense.

Scientific studies on Coptis chinensis focus on its major alkaloid, berberine, which has demonstrated antimicrobial and anti-inflammatory properties. However, there is a lack of robust clinical trials specifically evaluating its efficacy for sinus congestion or sinusitis. Most evidence remains preclinical or anecdotal, and the herb’s use in this context remains guided by traditional practice rather than established scientific validation. Therefore, while there is a historical basis for using Coptis chinensis in formulas for upper respiratory complaints, scientific support for its effectiveness in treating sinus congestion per se is limited.
