Scientific Evidence Levels

A coarse signal of how claims are supported: traditional attribution, regional compendia, or clinical literature.

[Traditional]Traditional Use

Reported cultural or historical use in herbals, teas, or local practice. Does not prove safety, dose, or efficacy for you or your region.

[Studied]Preliminary Research

Early or limited lab, animal, or small human work. Findings are not treatment guidelines and may not replicate.

[Clinical]Clinical Evidence

Structured human studies may exist, but strength varies by design, population, and outcome. Still not a substitute for qualified medical advice.

[Caution]Contraindications

Pregnancy, drug interactions, toxicity, and vulnerable groups require professional screening. FloraLexicon does not diagnose or prescribe.

Higher rungs mean more formal study—not that a plant is safe or appropriate for any use.

In FloraLexicon

Dataset evidence tags map to these bands so you can compare species without treating a label as medical advice.
