Why this scored 48/100
Evergreen Apothecary Calm Colon Tincture features yellow dock (Rumex crispus) for constipation support, positioning it as safe for daily use without dependency risk. Yellow dock contains anthraquinone glycosides — the same chemistry family as cascara sagrada, senna, aloe latex, and rhubarb root — that stimulate intestinal motility through colonic bacterial hydrolysis to anthrones. Yellow dock's anthraquinone content is lower than cascara or senna, but the chemistry is the same class the EU restricted in food supplements (Commission Regulation 2021/468 covering hydroxyanthracene derivatives from Rhamnus, Aloe, Cassia senna, and Rheum) due to genotoxicity concerns. The product page's claim that yellow dock is safe for daily use without dependency risk contradicts stimulant-laxative pharmacology — chronic stimulant laxative use (any anthraquinone-based agent) can produce cathartic colon changes and functional bowel dependence. Rejected under safety_concern for the daily-use positioning of a stimulant-laxative herb.

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.
