Pau d'Arco — taheebo — is the inner bark of the Lapacho tree, a large flowering hardwood found throughout South and Central America. The Incas and indigenous Amazonian peoples used it to treat infections, fever, and inflammatory conditions. Its primary active compound lapachol and the naphthoquinone beta-lapachone have demonstrated potent antifungal, antibacterial, antiviral, and antiparasitic activity in research. It remains a cornerstone herb in South American traditional medicine for candida, chronic infections, and immune rebuilding.
