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

How to interpret Pueraria Mirifica
Pueraria Mirifica dosage ranges, effects, drug interactions, and harm-reduction safety guide for hormonal. 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 Pueraria Mirifica, 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.
