High caution
Caution level: High. Multiple caution categories apply, or the record uses avoid/contraindication language.
- Stimulant-Like ProfileStimulant-like or activating caution language is present.
- 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.

- Consistency
- Consistent
Strongest recorded design is a randomized controlled trial, drawn from 3 recorded studies, 3 in people. No disagreement is recorded across them.
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
