Documented use categories

Medicine

These categories describe the kinds of human-use reports attached to the taxon in the source checklist. Multiple categories can coexist; a plant may be recorded as both food and poison, depending on part, preparation and context.

How to interpret this record

Evidence boundary

A taxonomic use record is a discovery and indexing signal. Clinical evidence must be assessed separately for the exact species, plant part, preparation, route, dose and health question.

Safety boundary

Correct identification is essential. Toxicity, contraindications, interactions and safe preparation cannot be inferred from a documented-use record.
