Pau D'Arco Overview:
Pau D'Arco is a large canopy tree of the Amazon rainforest. The inner bark of this tree has been used for hundreds of years as an antibacterial, antifungal, and antiparasitic.
In recent years, the antibacterial activity of Pau D'Arco has been well proven, and mainly attributed to the naphthoquinone content of the bark and phenolic content of the leaves.
Some of the most significant research on pau d'arco in recent years has been on its ability to reduce tumors. The quinone content, including lapachol, have shown significant anticancer activity when included in the whole plant extract. In isolation, these chemicals bring with them side effects including severe nausea and anti vitamin K activity.
Bacterial and fungal infection including candida. Not effective for E. coli.
