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.

A

Strong

Multiple RCTs, consistent direction, adequate effect size

B

Moderate

Some RCTs or consistent observational data in humans

C

Preliminary / Mixed

Animal or in-vitro only, or conflicting human data

D

Traditional / Theoretical

Traditional use only; no controlled human trials

Dosing & Timing

Dose guidance

Preparation specific; use standardized product label for Root/bark extracts containing berberine and require source backed dosage review before therapeutic claims.

Botanical profile context

How to interpret Berberis

Berberis dosage ranges, effects, drug interactions, and harm-reduction safety guide for anti inflammatory. Strong Human Evidence research evidence. 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 Berberis, 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.
