Traditional Plant Claim Check Matrix

A matrix with an explicit standard rather than a general sense of plausibility.

The standard has four levels. Widely tested, some evidence, traditional only, and contradicted. Assigning a claim to a level requires justification, which is what stops this becoming a vote.

The page has the matrix, the four levels defined, twelve claims and teacher notes. It also has an honest passage about why traditional only is not the same as false. Many things worked long before anyone tested them, and the absence of a study is a fact about the research, not about the plant.
