Buy Pau D'arco Bark: Lower Stress

By Pierre Federkeil

Pau d'arco (Tabebuia avellanedae) is native to South America, where reportedly it has been used to treat a wide range of conditions, including pain, arthritis, inflammation of the prostate gland (prostatitis), fever, dysentery, boils and ulcers, and various cancers.

Although preliminary lab tests show that a chemical in pau d'arco called lapachol can kill some viruses, bacteria, and fungi in test tubes, it isn't known whether it will have the same effects when taken by humans. So even though pau d'arco is sometimes used for conditions ranging from candidiasis (a yeast infection of the vaginal or oral areas), herpes simplex virus, and influenza to parasitic diseases such as schistosomiasis and bacterial infections such as brucellosis, there is no evidence it works. Test tube studies to evaluate whether pau d'arco has any effect on cancer have shown mixed results; and even in studies where pau d'arco does reduce the number of cancer cells, the amounts used would be toxic to humans.

In spite of this negative report, pau d'arco has since been used successfully to treat such things as fevers, arthritis, infections, malaria, skin problems, cancers, and even complications of AIDS. Two reasons for the discrepancy between the research and reality are these.

A study at the University of Rio de Janeiro discovered that pau d'arco helps treat Staphylococcus aureus infections that resist antibiotics. Research at Seoul National University suggests that the herb is active against human intestinal bacteria, which cause food poisoning.

Most of the chemical research on pau d'arco has been done on the wood and not the inner bark. Pau d'arco contains chemical compounds called naphthoquinones such as lapachol that may have antifungal, antiviral, and antibacterial properties, as well as significant amounts of the antioxidant quercetin.

Pau d'arco is sold as tablets, dried bark tea, and tincture (which contains alcohol). The chemicals that give pau d'arco its medicinal effects dissolve poorly in water, so a tea is not recommended.

Early reports declared pau d'arco to be useful in treating leukemia and other cancers, but the National Cancer Institute's research into lapachol (the constituent with the most anti-tumor activity) was halted due to mild side effects. More recent lab tests in Korea determined that another constituent, beta-lapachone, kills cancer cells of the lung, colon, and prostate. Pau d'arco is some time away from being used to treat cancer, but the Incas may have been on the right track.

Pregnant and nursing women should not use pau d'arco until it is sufficiently researched. Pau d'arco has been shown to have blood-thinning actions in some people, and may cause anemia when used long term. Possible side effects from ingesting too much pau d'arco include nausea, vomiting, diarrhea, dizziness, and stomach cramps. Another precaution consumers should heed is assuring that the product they purchase is produced by a reputable manufacturer. Some tested have very few active ingredients. The pau d'arco imported from Argentina is generally considered to be the highest quality bark. - 17269
