Documented use categories
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

Traditional and practical context is preparation-specific. A documented use category is not proof of clinical effectiveness.
Evidence boundary
Evidence must be assessed by exact species, plant part, preparation, route, dose and health question.
Safety boundary
Confirm botanical identity, plant part, route, dose, medicines, allergies, pregnancy, breastfeeding and age before use.
