Evidence-based safety
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

What the evidence actually shows
This table contains 3 structured sources, including 0 human evidence sources; 0 are human trials. A reliable participant total cannot be calculated because sample size is not consistently structured in the cited sources. Source-to-conclusion relationships are not classified in this structured set, so consistency is not yet classifiable.
Profile-wide evidence grade: see the profile grade above · Confidence: not separately assigned
What would change our conclusion?
Larger, well-controlled human trials using comparable populations, doses, preparations, and clinically meaningful outcomes could materially strengthen or weaken this conclusion. Replication in a different population or a high-quality synthesis resolving current disagreement could also materially change confidence.

Botanical profile context
How to interpret Sophora Flavescens
Sophora Flavescens herb profile with evidence context, key research topics, source notes, safety context, and references presented in an evidence-first… Use this herb profile as a starting point for evidence review, not as a recommendation to start a new supplement. Botanical products can vary by plant part, extract ratio, standardization, dose, and contaminant testing, so two labels with the same common name may not behave the same way.
When reviewing Sophora Flavescens, compare the traditional-use context against the human evidence, mechanism notes, and safety cautions. Pay special attention to pregnancy, breastfeeding, liver or kidney disease, blood-pressure effects, sedation, stimulation, anticoagulant use, antidepressants, and any prescription medication overlap.
For product decisions, prefer transparent labels, named extracts, clear serving sizes, and third-party quality testing. Avoid treating a long list of possible mechanisms as proof that an herb will solve a specific condition.
