What the study reported
Verified extract — not AI generated
“The likely user benefit should be interpreted cautiously until the full paper is reviewed for sleep quality, relaxation, safety, and evidence-based dose context.”
Dose in the study
Use context could not be reliably extracted from metadata alone and should be verified during curation.
Side effects noted
No adverse effects reported in the indexed studies.
Caveats
This fallback uses metadata ranking and should be upgraded with full AI or manual review before stronger claims.
