Traditional Herb Claim Evidence Ladder

Six rungs, from single anecdote through traditional consensus to controlled trial and systematic review.

The ladder makes the standard explicit rather than intuitive, and placing a claim requires knowing what kind of evidence exists rather than whether it sounds plausible.

The page has the ladder defined, claims to place, and a research task to find where the evidence actually sits. It also carries the caution that a low rung is not a refutation, and that the honest position for much traditional plant use is that it has not been properly studied rather than that it does not work.
