How to interpret this record
Traditional and practical context
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.
