Jade Dragon Cool Sinus Herbal Supplement 200 Pills EXP 11/2028

Six-dimension breakdown

Why this scored 43/100

Jade Dragon Cool Sinus is a Traditional Chinese Medicine (TCM) patent formula — specifically Bi Yan Wan, a classical multi-herb combination historically used in TCM practice for nasal congestion and sinus inflammation from wind-cold or wind-heat pattern presentations. The formula typically contains 12-15 herbs including Cang Er Zi (Xanthium sibiricum fruit), Xin Yi (Magnolia biondii flower bud), Bai Zhi (Angelica dahurica root), Fang Feng (Saposhnikovia divaricata root), Ju Hua (Chrysanthemum morifolium flower), and others in specific proportions. Two significant flags apply. First, the Cang Er Zi component contains sesquiterpene lactones with documented hepatotoxicity risk — multiple published case reports have linked Xanthium-containing TCM preparations to acute hepatitis, and the FDA has monitored the class. Second, TCM patent formulas as a category have persistent quality control issues in retail distribution: mainland-Chinese-manufactured tea pills have been repeatedly identified as containing undisclosed pharmaceutical adulterants (corticosteroids, NSAIDs, antihistamines), heavy metal contamination, and mislabeled ingredients. Without visible US-market third-party assay, GMP certification, and independent contamination testing, this falls into the proprietary_blend_hides_dose category — no per-herb milligrams are disclosed, safety cannot be verified. Rejected.

Evidence & sources

The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.

Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

How to read the Evidence dimension

• 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
• 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
• 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
• 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
• 0–19: No credible evidence base or unverifiable claims.
