Tabebuia impetiginosa; formerly T. avellanedae
Pau d'arco has been studied well with early results promising. Research on anticancer activity was conducted in the late 1960s and early 1970s by the National Cancer Institute. Analyses of commercial products have found that many lack the known active constituents.
What is this miracle bark?
It's called Pau d'arco (pow-DAR-co). The actual meaning of the word is "bow stick", which refers to various trees of the Tabebuia family that can be found growing in the mountains of Brazil, Argentina, Bolivia, Paraguay and Peru.
More recently, Brazilian researchers studied and did confirm that the ancient Pau d' arco is indeed anti-bacterial naturally. Even more recent studies confirm:
- In Rio de Janeiro a study was conducted at the University and confirmed that pau d' arco does help treat Staphylococcus aureus infections, even when it resists antibiotics.
- The Seoul National University conducted a study that suggests pao d' arco is active against human intestinal bacteria that cause food poisening.
- The National Academy of Sciences confirmed that pau d' arco contains anti-inflammatory properties as well as anti-viral activity, including against herpes I and II.
