The term “Paui” is a common misspelling of Pau d’Arco, which refers to a traditional herbal remedy. This remedy is derived from the inner bark of specific trees native to the Amazon rainforest. Pau d’Arco has been used for centuries in traditional practices for its wellness properties. While “Paui” might appear in searches, the correct term is “Pau d’Arco.”
Understanding Pau d’Arco
Pau d’Arco originates from the inner bark of several Tabebuia species, most notably Tabebuia impetiginosa or Tabebuia avellanedae, which are large canopy trees found in Central and South American rainforests. The name “Pau d’Arco” itself is Portuguese for “bow tree,” reflecting its historical use by indigenous peoples for crafting hunting bows. Indigenous cultures have used this inner bark for various ailments, general wellness, and as a tonic for over 1,500 years.
Active compounds in Pau d’Arco are naphthoquinones, primarily lapachol and beta-lapachone. These compounds, along with others like flavonoids and benzenoids, are extracted from the bark. Research has explored their properties in laboratory settings.
Potential Health Applications
Pau d’Arco has been used to support the immune system. It is also associated with anti-inflammatory properties, with compounds in the bark believed to reduce inflammation. This traditional use extends to managing conditions like arthritis and other inflammatory issues.
Pau d’Arco is also thought to possess antimicrobial and antifungal effects. Historically, it has been applied to combat various infections, including fungal and yeast infections. It has also been used against bacterial and viral concerns.
Important Considerations for Use
Pau d’Arco is available in various forms, including teas, tinctures, capsules, and powders. General dosage guidelines exist, such as 1-4 grams per day divided two to three times daily for no more than seven days; however, these are not medical advice, and individual needs vary. It is often suggested that lapachol intake should be around 1.5-2.0 grams per day.
Side effects, especially at higher doses, can include nausea, vomiting, and dizziness. High concentrations of its active compounds may also lead to anticoagulant effects, increasing the risk of bleeding. Pau d’Arco is possibly unsafe during pregnancy due to the risk of pregnancy loss and should be avoided by individuals with bleeding disorders or those undergoing surgery. It can interact with blood-thinning medications and NSAIDs, and its long-term safety is not well-established. Consulting a healthcare professional before use is important.
Sourcing and Quality
When selecting Pau d’Arco products, seek reputable suppliers. Products should ideally specify the Tabebuia species used, such as Tabebuia impetiginosa or Tabebuia avellanedae. Consider sustainable harvesting practices due to increasing demand impacting wild populations. Some companies work with environmental agencies to ensure adherence to sustainable practices. Check for third-party testing for purity and potency to ensure the product contains the intended active compounds.
