Caution when combined
Severity and certainty are shown separately. A high-priority caution can still be theoretical: these pairings are screened from shared contraindication mechanisms and are not automatically documented clinical interactions. Provenance identifies the source fields that produced each flag; it does not upgrade the certainty of the pairwise claim.

How evidence grades work
Each grade reflects the strength and consistency of published human evidence — not marketing claims. Grades are based on study count, design quality, effect size, consistency, and recency.
- Strong
- Multiple RCTs, consistent direction, adequate effect size
- Moderate
- Some RCTs or consistent observational data in humans
- Preliminary / Mixed
- Animal or in-vitro only, or conflicting human data
- Traditional / Theoretical
- Traditional use only; no controlled human trials

|---|---|---|---|---|---|---|---|---|
Background | Systematic review Uses a predefined method to find and evaluate relevant studies, but may or may not pool their results statistically. | — | — | — | — | — | A systematic review found the clinical evidence for kudzu/Pueraria preparations too heterogeneous and limited for confident therapeutic conclusions, despite promising signals in some alcohol-use and metabolic studies. | PubMed → |
Background | Randomized controlled trial Randomly assigns participants to interventions or controls, reducing many sources of bias when the trial is conducted well. | — | — | — | — | — | In a randomized trial of chronic alcohol use, kudzu root at 1.2 g twice daily did not significantly improve craving or sobriety outcomes versus placebo. This is useful negative evidence and should sit beside more favorable alcohol-consumption studies. | PubMed → |
