Evidence grows. Every claim shows where it stands.
Tradition tells researchers where to look, and trials show what holds up. We rate each use of a remedy separately, so ginger can be promising for nausea and unproven for colds.
Not enough evidence
Too few good human studies to say yet. Not shown is different from shown not to work.
Promising but early
Positive results from small, early or mixed trials. Worth knowing about, and worth raising with your clinician.
Strong evidence
Our top rating. Consistent results from good human trials or reviews.
Evidence says no, or unsafe
Tested properly and failed, or linked to documented harm.

How every guide is made
Sources you can check
Each guide lists its sources, from NIH and European regulators to peer-reviewed trials, numbered where they're used.
Graded one use at a time
A remedy can be strong for one job and unproven for another, so every use gets its own rating.
Respect for tradition
We record how healing traditions have used a plant, and say plainly where that history has and hasn't been tested.
Reviewed and dated
Every guide shows the month it was last reviewed, so you know how current the evidence is.
