Source Naturals Pau D’Arco 500mg




It’s no surprise that inflammation is one of the leading causes of disease. The human body should be in perfect balance with no internal inhibitions. If arteries are clogged, joint and muscles are swollen, or any type of excess is present, organs, joints, and muscles can’t optimally perform. To restore (or maintain) balance in the body, you need to limit inflammation. Pau D’Arco has been used for centuries as an all-natural source for reducing inflammation in the body as well as a host of other physical ailments that limit normal body function.

Pau D’Arco is an herbal supplement from the inner bark of several species of Tabebuia trees. These trees grow in the rainforests of Central and South America, where civilizations have thrived for years. Source Naturals’ Pau D’Arco is the highest quality inner bark of the Purple Lapacho tree found in Brazil and Northern Argentina. The native tribes of these countries have used Pau d’Arco as a treatment for stomach, skin, and inflammatory conditions. Additionally, they’ve used them to support healthy immune response to pain, arthritis, inflammation of the prostate gland, fever, dysentery, as well as boils and ulcers.

Essential Compounds In Pau D’Arco

There are two critical compounds in Pau D’Arco that provide these health benefits: lapachol and beta-lapachone. Both are naphthoquinones, which are wide-spread phenolic compounds that naturally exist in nature. Phenol compounds are gaining notoriety in health recently since many of them naturally occur in fruits and vegetables.

Research suggests phenols may have the potential ability to reduce inflammation that may lead to cancer. Additionally, the consumption of vegetables and beverages that are rich in phenol may reduce the risk of numerous diseases due to their antioxidant abilities.


Lapachol is present in the inner bark of Pau d’arco trees. Research shows lapachol may be an effective natural medicine for use in treating abscesses and shows potential in being antiviral, antimicrobial, and anti-inflammatory.


Beta-lapachone has been isolated from the Tabebuia tree to study its benefits. There is extensive and promising research on beta-lapachone’s ability to stimulate autophagy (death of cells). This is extremely beneficial for cancer patients, since targeting and causing the death of cancer cells (what chemotherapy does) can help with remission.

An Essential Supplement

Aside from the numerous benefits of these two compounds, both also contain quercetin. Quercetin is a plant flavonoid that is present in multiple plants and foods. Red wine, onions, green tea, apples, various berries, Ginkgo biloba, and St. John’s wort are a few. Quercetin supports healthy heart and blood vessel function. Additionally, patients with arthritis, bladder infections, and diabetes typically use quercetin to alleviate adverse symptoms.

With these two key compounds that support healthy immune response to inflammation while promoting blood cleansing, Pau D-Arco has become an essential supplement for balancing your body’s health and promoting homeostasis.

Suggested Use: 1 to 2 tablets twice daily between meals.

Note: Infants and children should not consume Pau D’Arco.
