The Pau D Arco tree is a tropical evergreen that grows in Central America, South America and the Caribbean. The medicinal effects of Pau D’Arco are attributed to lapachol.
Key Health Benefits of Pau D Arco
Pau D’Arco has also been found to have antiviral activity against cold sores, and anti-protozoal activity against malaria. Topically, Pau D’Arco tea can be used to treat bacterial and fungal infections, bites, minor skin injuries and psoriasis.
What Parts of Pau D Arco Are Used Medicinally?
Pau D’Arco’s most medicinally effective part is the inner bark. Unfortunately harvesting the inner bark often results in the death of the tree. Increased demand for this tree has made Pau D’Arco an endangered species in some South and Central American countries. You may want to inquire as to the harvesting practices of the company that provides the raw material for you.
Pau D Arco Supplement Varieties
Pau D’Arco supplements are made from a variety of species in the genus Tahebuia. Some supplements are made from the inner bark while others are a mixture of the bark with other less active plant parts. Few Pau D’Arco supplements are standardized to the lapachol content. All of these factors make it difficult to use Pau D’Arco safely. Due to the toxicity of lapachol internal use of Pau D’Arco is best undertaken with the guidance of a health professional.
Pau D’Arco is available as dried bark, for tea, and encapsulated tree parts. Tea is traditionally used for its medicinal properties but very few of the medicinally active components of Pau D’Arco are water-soluble. Encapsulated dried bark, which is standardized, is the best supplemental form of Pau D’Arco.
Cautions & Considerations
Individuals with active bleeding or blood disorders should not use pau d’arco. Pau D’Arco interacts with blood thinners, aspirin and any herbal product that thins the blood. Pau D’Arco is not safe for use in pregnant and nursing women. High doses of lapachol can lead to anemia, diarrhea, dizziness, nausea and vomiting.
