The Incredible Benefits of Pau D’Arco Bark in Herbal Supplements

You may have never heard of pau d’arco bark. But it is a powerful herbal tool used by indigenous tribes in the Amazon basin for centuries. 

And it’s an herb Dr. Rydland uses in several of his supplements because of its medicinal properties.

Let’s learn more about pau d’arco bark’s uses and benefits.

What is pau d’arco bark?

Pau d’arco bark comes from the inner bark of the Tabebuia impetiginosa or Tabebuia avellanedae tree species. If you’ve seen trumpet trees, then you’re familiar with the Tabebuia tree because they’re from the same plant family.

The outer bark of a Tabebuia tree is dark to reddish brown with a rough and deeply furrowed texture. The inner bark is lighter (from pinkish to pale purple) with a fibrous texture. And after drying, the bark is used in herbal preparations.

What are the benefits of using pau d’arco bark?

Several active compounds in pau d’arco bark make it beneficial. The bark contains naphthoquinones like lapachol and the antioxidant quercetin, which shows therapeutic qualities.

Here are some of the primary benefits of using pau d’arco bark in herbal supplements:

Immune support

Pau d’arco bark supports the immune system by improving the body’s ability to fight off infections.


Pau d’arco bark also helps fight inflammation from infections or other disorders (like arthritis).


The antioxidants in pau d’arco bark help neutralize free radicals and oxidative stress in the body.

Antimicrobial & antifungal

Pau d’arco bark is also helpful in fighting certain bacteria and fungal infections.

Gastrointestinal support

Who shouldn’t take pau d’arco bark?

Pau d’arco bark is considered safe when used appropriately. But some individuals shouldn’t take it or only take it after consulting their doctor.

  • Pregnant or breastfeeding women: There is limited information on the safety of using pau d’arco bark while pregnant or nursing.
  • People with bleeding disorders or on anticoagulant medication: Pau d’arco bark has mild blood thinning properties and can interact with blood thinners or bleeding disorders.
