Pau d‘arco is said to treat numerous conditions including, cancer, Candida overgrowth, constipation, fibromyalgia, diabetes, lupus, bacterial infections, viral infections, and various parasites. Pau d’arco strengthens the body’s immune system, detoxifies the liver, treats various ailments, contains many antioxidants, and is said to promote overall health.
What Is Pau d'Arco?
Pau d‘arco is a large canopy tree indigenous to tropical regions of South America, from the Bignoniaceae family, the Tabebuia genus, and the impetiginosa species. These flowering trees are often chosen in tropical landscaping for their beauty and durability. They can grow up to 30 meters tall and 3 meters wide. Pau d’arco trees only grow in tropical regions, so they can only be grown in the U.S. in Hawaii and southern Florida.
History of Pau d'Arco Use by the Western World
The Portuguese learned that the bark was useful in treating tropical diseases, including the problematic schistosmiasis caused by flatworms. After this, the incorporation and use of pau d‘arco within traditional herbal medicine spread to Europe and later North America. Widespread knowledge of pau d’arco was not seen until the late nineteenth century when scientists isolated one of the active ingredients, lapachol, and identified its chemical structure. Lapachol was first synthesized in the 1920s.

Pau d'Arco and Cancer
Like many natural remedies, especially those with claims to heal cancer, information found is contradictory. There are reports of widespread use to heal cancer with miraculous shrinkage and elimination of tumors and reports of curing leukemia countered with warnings that claim the dosage needed to cure cancer would be toxic and may cause internal bleeding.

Pau d'Arco Research Issues
One problem with most of the scientific research on this herb is the focus on the isolated compound, lapachol, typically a synthesized version. Pau d‘arco contains other helpful compounds such as quinoids, benzenoids, flavonoids, and beta-lapachone. The side effects of the isolated lapachol are more intense than the side effects of the whole pau d’arco herb.
Pau d'Arco Warnings
There are strong warnings against using pau d‘arco when pregnant or lactating and not giving it to children. These warnings are not generally explained, but large quantities are known to cause digestive upset and bleeding. Be wary of prescription drug interaction, especially with blood thinners. Others warn that too high a dose could weaken immunity. There are also warnings that not all supplements claiming to be pau d’arco contain the correct herb. Obviously, if using pau d'arco to treat a serious disease, consulting a knowledgeable and experienced naturopath will help you determine the correct dosage and schedule and help you source a reputable brand.
