What is known.
What remains uncertain.
Daily source records, trials, methods, limitations, and plain-language explanations for people who want to read beyond the headline.
Educational boundary. A registered trial is not proof of effectiveness. A study result may not apply to another person, setting, dose, medication list, or medical history.
Evidence levels
Do not flatten every source into “research says.”
Evidence from controlled research
Relevant controlled human research, with population, methods, and limitations shown.
Early or observational evidence
Preliminary, uncontrolled, indirect, or limited evidence.
Reported experience or traditional context
Personal, community, historical, or cultural knowledge—not presented as clinical proof.
Insufficient or conflicting evidence
The available evidence does not support a reliable conclusion.

01
Clinical trials
New and updated registry records. Registration does not establish safety, effectiveness, completion, or published results.
02Safety & interactions
Adverse-event, toxicity, contraindication, interaction, monitoring, and harm-reduction records.
03Systematic reviews
Systematic, scoping, umbrella, and meta-analytic records with methods and limitations still requiring appraisal.
04Case reports
Individual reports and small series that may identify signals but cannot estimate typical outcomes.
05Preprints
Public manuscripts that may not have completed peer review and may change or be withdrawn.
06Policy & law
Government and regulatory records. Legal meaning depends on exact activity, jurisdiction, entity, and date.
07All new records
The available automated discovery ledger across indexed sources and registries.
