Goldthread (Coptis chinensis) has a long history of use in Traditional Chinese Medicine (TCM), where it is primarily valued for its "heat-clearing" and "detoxifying" properties. The active compound in Goldthread, berberine, is known for its broad-spectrum antimicrobial effects. In TCM, Goldthread is often included in formulations aimed at treating "hot" conditions, which can include sinus congestion or infections, especially those associated with yellow or thick mucus (a sign of "heat" or infection in TCM theory). However, the historical use relates more to general infections and inflammations of the upper respiratory tract rather than specifically targeting the sinuses as understood in Western medicine.

From a scientific perspective, while berberine and related compounds have demonstrated antimicrobial and anti-inflammatory activity in vitro and in animal studies, there is limited clinical research directly evaluating Goldthread or its extracts for sinus health or sinusitis in humans. Thus, its use for supporting the sinuses is justified primarily by tradition, with low-to-moderate evidence based on historical application and biological plausibility rather than robust clinical trials.
