Compound Profile

Saw Palmetto Extract

Saw palmetto extract has high quality negative evidence for BPH symptom improvement versus placebo despite plausible anti androgen mechanisms.

Use extra caution — GI upset, headache; caution anticoagulants and hormone sensitive conditions. Details

Safety

Safety & Cautions

GI upset, headache; caution anticoagulants and hormone sensitive conditions.

High caution

Caution level: High. Multiple caution categories apply, or the record uses avoid/contraindication language.

  • Hormonal Activity ContextHormone-adjacent wording is present and should be interpreted carefully.
  • Anticoagulant CautionBleeding or anticoagulant-adjacent caution language is present.
  • Pregnancy/Breastfeeding CautionPregnancy or breastfeeding caution language is present.

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
