Transparency
How we grade
Every claim gets one letter, based only on the strength of the evidence. Not on how old the remedy is, how popular it is, or who profits from it.
- AStrong evidence
- BModerate evidence
- CLimited evidence
- DTraditional, untested
- FWe advise against this
What the grade means
The grade answers one question: how well-supported is this specific claim? Provenance — whether something is traditional or clinical, and which culture it comes from — is recorded separately and never changes the letter. A beloved traditional remedy can be a C, D, or F. Evidence of harm forces an F no matter what.
Why "no evidence" isn't "bad"
An untested traditional remedy is a D — honestly labelled as heritage, not proof. We reserve F for things with real evidence of harm. Confusing those two is the most common way honesty slips.
