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.
