Pau D'arco

Pau d'Arco, derived from the inner bark of the Tabebuia avellanedae tree native to Central and South America, has a long history of traditional use among indigenous communities and has drawn modern scientific interest for its bioactive compounds, particularly lapachol and beta-lapachone. Research suggests these naphthoquinone compounds may exhibit anti-inflammatory, antimicrobial, and immune-modulating properties, with laboratory studies showing activity against certain bacteria, fungi, and parasites. Studies also indicate potential analgesic effects, though much of the existing evidence comes from in vitro and animal research, meaning human clinical trials remain limited. Commonly consumed as a tea brewed from the dried inner bark, Pau d'Arco continues to be explored as a subject of interest in ethnobotanical and pharmacological research, with scientists working to better understand its mechanisms and safety profile.
