Identity and form
Pau d'Arco is inner bark from a declared Handroanthus or Tabebuia species; lapachol-related constituent exposure varies.
The label should identify the source, form, preparation, and active or marker amount when those details determine comparability.
What the evidence can answer
Human research has examined Pau d'Arco in relation to immune function, antioxidant and redox pathways. The amount, source, preparation, population, comparator, and measured outcome determine whether a result applies to a finished product.
Current WQ evidence label: Limited human evidence. This label describes the present evidence context, not a promise of benefit.
Safety and decision context
High-caution knowledge. Combination with anticoagulant or antiplatelet therapy requires professional review. Pregnancy and breastfeeding safety is uncertain or specifically cautioned. This substance has drug-like pharmacology or a drug/supplement boundary that requires specialist review.
Review medicines, pregnancy or breastfeeding, allergies, medical history, and the complete finished label with a qualified professional when relevant.
