The bark and wood of the tree are used externally and internally to treat:
· arthritis
· pain
· inflammation of the prostate gland
· fever
· dysentery
· boils
· ulcers
· various cancers
One of the easiest ways to use pau d’arco is by consuming a tea made from the inner bark of pau d’arco or applying the tea water to the skin.
What Is Pau D’arco?
Pau d’arco, also called taheebo, is an evergreen tree that has rose-colored flowers. There are nearly 100 species of pau d’arco, but only a few yield high-quality material. It takes extremely skilled gatherers to know what species are the most effective. Two well-researched and used species are lapacho, tabebuia, impetiginosa, and red lapacho tabebuia.
The medicinal part of the tree is the bark, specifically the inner lining of the bark, called the phloem (pronounced floam). Unfortunately, many companies use the whole bark, containing the dead wood too, and this naturally dilutes the activity of the material.
The bark of tabebuia Avellaneda is valued for its powerful and therapeutic phytochemicals. Research on red lapacho tabebuia identified two active chemicals in pau d’arco called naphthoquinones: lapachol and beta-lapachone.
These chemicals have the power to kill bacteria, fungi, viruses and parasites. They have also shown anti-inflammatory properties, which are important in treating health conditions such as osteoarthritis.
Benefits
1. Rich in Lapachol and Other Antioxidants
Pau d’arco tea contains several compounds, including quinoids, benzenoids and flavonoids. These compounds have displayed biological activity against harmful organisms.
Pau d’arco also has a significant amount of lapachol, which comes from the stem of the tree. The U.S. Department of Agriculture indicates that lapachol is known be toxic and resistant to nearly all types of harmful organisms.
A 2005 study published in Oncology Reports found that lapachol has great potential as an application in fighting metastasis, which is the spread of a cancer or other disease from one organ of the body to another. Metastasis is the major process responsible for the death in cancer patients, and recent research involving lapachol is promising.
Lapachol is also used for its antioxidant and antimicrobial effects, but some research suggests that high doses of this compound can lead to dangerous side effects, like reproductive toxicity. Pau d’arco also contains another chemical called beta-lapachone, which has also demonstrated toxicity to harmful organisms, similar to lapachol.
2. Reduces Pain
Research shows that pau d’arco tea has the power to naturally reduce pain in patients suffering from cancer and other serious health conditions. It has the ability to lessen the pain associated with several kinds of cancer, especially cancer of the prostate, liver or breast.
Consuming pau d’arco tea has also been found to help relieve arthritic pain.
A 2001 study published in BMC Pharmacology examined the ant nociceptive (pain-reducing) and antiedematogenic (to reduce swelling) effects of pau d’arco inner bark, measured by experimental models in mice that underwent pain stimulated by nerve cells. The inner bark aqueous extract, administered orally in three different concentrations, reduced the sensory process that provides the signals that lead to pain.
3. Fights Candida
Pau d’arco helps the body fight candida. Candida, also known as candidiasis, is a common yeast infection that has been proven to contribute to many health problems, from a sore throat to serious stomach problems.
The body normally produces yeast in the mouth, vagina, rectum and digestive tracts, and in normal amounts it remains harmless. However, if the body’s natural pH balance is upset, candida symptoms can quickly grow out of control.
4. Reduces Inflammation
An overactive immune system results in the body being flooded with defense cells and hormones that damage tissues.
Dietary and environmental toxins build up in the body, and this turns the immune system on — keeping it highly reactive. This is what leads to inflammation, which is at the root of most diseases.
A 2014 study published in the Journal of Toxicological Sciences found that Pau d’arco increased the expression of Nrf2-target genes in the intestine. Nrf2 is a protein that regulates the expression of antioxidant proteins that protect against oxidative damage triggered by injury and inflammation.
The results of this study show that the activation of Nrf2 could mediate the beneficial effects of pau d’arco, particularly in the intestine, which can be severely affected by inflammation.
5. Helps Treat Ulcers
Ulcers are burns that form in the lining of the upper part of the gastrointestinal tract.
When they occur in the stomach, they’re called gastric ulcers. If they form in the first part of your small intestine, the duodenum, they’re referred to as duodenal ulcers.
Peptic ulcer disease begins when a weakness in your stomach or intestinal lining allows acid to create an erosion or sore in the lining. It’s the most common type of stomach disease, according to the American Gastroenterology Association.
Ulcers are caused by an increase in stomach acid caused by stress, medications, diet, smoking, alcohol or H. pylori, a type of bad bacteria. The most common ulcer symptom is a burning pain aggravated by stomach acid that comes in contact with the ulcerated area.
A 2013 study published in Phytotherapy Research found that pau d’arco extract significantly accelerated the healing of acetic acid induced gastric ulcers in rats by increasing mucus content and cell proliferation. This suggests that pau d’arco could be a treatment for peptic ulcer diseases in humans.
