Safety & Cautions
Food like use is generally lower risk, but concentrated extracts may not match dietary safety. Use caution with pregnancy/breastfeeding, allergy, and chronic high dose supplementation.
High caution
Caution level: High. Multiple caution categories apply, or the record uses avoid/contraindication language.
- Interaction-AwareMedication or interaction context is explicitly noted.
- Liver-SensitiveLiver-related caution language appears in the profile.
- 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.

Study design details
Evidence Grade
Grade C: Limited Evidence
Evaluation of methodological rigor, population reach, and evidence alignment.
- Design Match
- Narrative review
- Risk of Bias
- High
- Consistency
- Not assessed
Strongest recorded design is a narrative review, drawn from 1 recorded study, none of which measured an outcome in people.
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
