Plant Story Source or Safety

Two separate questions that students collapse into one. Where did this come from, and is it safe.

A claim from a trusted person can still be unsafe. A claim from an unreliable source can still be correct. Keeping the two axes apart is the skill.

The page has a two axis grid, twelve claims to place, and teacher notes with the current position. It also carries the standing rule about natural not meaning safe, restated because it needs restating, and a short list of plants in the region that genuinely cause harm and are still widely recommended.
