The Active Ingredient Is: Pau d'Arco Extract

Pau d'Arco extract is derived from the inner bark of the Tabebuia impetiginosa tree and used in the form of a 5:1 concentrate to provide a potent botanical extract. This form is prepared to deliver the bioactive components associated with traditional use for immune support and microbial balance.

The extract is produced as a concentrated botanical powder encapsulated in a vegetable shell, reflecting sustainable sourcing and organic certification principles associated with this type of product.

What Does Pau d'Arco Extract Do?

Pau d'Arco contains bioactive compounds such as lapachol and beta-lapachone that exhibit antioxidant and anti-inflammatory properties and may have antifungal activity. It may support immune function and microbial balance by helping the body counteract oxidative stress and maintain a balanced internal environment.

These actions contribute to normal immune and microbial regulation, supporting daily wellness through natural plant-based mechanisms.
