The Benefits of Pau d'Arco
6 health benefits of pau d’arco
Pau d’arco has been extensively researched for its alleged therapeutic qualities.
Here are six potential benefits of using pau d’arco.
1. Reduces inflammation
Pau d'arco can help reduce inflammation due to its high concentrations of naphthoquinones and phenolic compounds.
Naphthoquinones such as lapachol, alpha-lapachone, and beta-lapachone have been found to inhibit inflammatory agents, including prostaglandin E2 and cyclooxygenase-2.
Moreover, phenolic compounds such as acteoside and isoacteoside in pau d’arco can help regulate inflammatory cytokine activity.
Cytokines are signaling molecules that can trigger and perpetuate inflammation. These compounds also affect various biological pathways involved in gene expression and immune system functions.
Naphthoquinones and phenolic compounds in pau d'arco synergistically mitigate inflammation and related symptoms such as pain, swelling, fever, redness, and stiffness. This may offer potential therapeutic benefits for inflammatory conditions.
A study published in the Journal of Ethnopharmacology observed the anti-inflammatory effects of pau d'arco in mice. The researchers concluded, "Pau d’arco extract may be developed as a new therapeutic remedy for various inflammatory diseases such as arthritis and atherosclerosis.”
2. Natural pain relief
Over-the-counter pain medications are among the most widely used drugs globally. However, these pharmaceuticals can cause gastrointestinal and cardiovascular issues, kidney problems, and increased blood pressure.
By reducing the activity of inflammatory cytokines, pau d'arco has been shown to help mitigate the pain associated with menstrual cramps and inflammatory conditions such as arthritis.
Pau d'arco offers similar pain-relieving effects as conventional painkillers but with a lower risk of adverse effects, making it a promising and potentially safer natural option for managing pain.
3. Potent antimicrobial remedy
"Pau d'arco displays potent antibacterial and antifungal activities, making it a potential remedy for microbial conditions such as oral thrush, candidiasis, and certain skin infections,” says Dr. Berg.
This has been confirmed in a study published in the Annals of Clinical Microbiology and Antimicrobials, showing pau d'arco's potent antibacterial activity in an in vivo dermal irritability analysis.
The findings revealed that lapachol is particularly effective against antibiotic-resistant bacteria, including Methicillin-resistant Staphylococcus aureus (MRSA). MRSA poses a serious health threat, potentially leading to severe infections, pneumonia, sepsis, or even death if left untreated.
4. Strengthens immune defenses
A robust immune system is essential for fighting pathogens and maintaining a healthy body.
Research published in the Arabian Journal of Chemistry found that pau d'arco is a rich source of quercetin, a potent flavonoid known for its immunomodulatory properties.
A study published in Molecules confirms the impressive immune-enhancing properties of Tabebuia impetiginosa extract.
The authors suggest that pau d'arco helped white blood cells operate more effectively. These cells play a critical role in immunity by destroying harmful microbes.
In addition, ethanol extracts of pau d'arco effectively modulated the activity of T-cells, a type of immune cell involved in the body's adaptive immune response.
By promoting balanced T-cell levels, pau d'arco may help prevent an overactive immune response, which can lead to autoimmune diseases such as celiac disease or rheumatoid arthritis.
5. Potential anti-cancer properties
Pau d'arco may have potential in cancer prevention.
A review study published in Expert Opinion on Therapeutic Patents summarizes that naphthoquinones in pau d'arco demonstrated potent anti-cancer effects towards various cancer cell lines.
Another study published in Molecules found that an extract of Tabebuia impetiginosa was able to hinder the growth of several in vitro cancer cells, including breast, lung, cervical, and hepatocellular carcinoma.
Pau d'arco also contains oleic acid, a health-promoting fatty acid found abundantly in olive oil.
According to research published in Cancers, "Oleic acid significantly inhibited cell proliferation and tumor growth in endometrial cancer cells," further highlighting pau d'arco's potential as a natural adjunct to traditional cancer treatment.
6. May support weight loss
A study published in the American Journal of Chinese Medicine focused on the role of pau d'arco in the prevention and management of obesity.
The researchers found that beta-lapachone administration prevented body weight gain in obese mice by reducing the weight of white adipose tissue, the body's primary site for fat storage.
The study also revealed that beta-lapachone could induce thermogenesis. This process involves the production of heat within the body, which can have implications for energy expenditure and weight management.
How to use pau d’arco
Pau d'arco is available in various forms, including dietary supplements, loose powders, liquid bark extracts, topical applications, and teas.
To make pau d’arco tea, steep 1 to 2 teaspoons of pau d'arco bark in eight ounces (240 milliliters) of hot water for about 15 minutes.
The tea has a slightly bitter, earthy taste that can be balanced by adding honey or lemon.
Here are three tips to help you find high-quality pau d'arco products.
1. Research the brand
Choose a brand that has a good reputation for producing high-quality herbal supplements and is transparent about its sourcing and manufacturing processes.
2. Check for third-party testing
Reputable companies often conduct third-party testing of their products to evaluate purity and potency. This ensures the supplement contains the desired compounds and is free from contaminants.
3. Read labels carefully
Check the label to ascertain the product contains 100 percent pure pau d'arco bark and no fillers or additives. The label should also specify the species of Tabebuia tree bark used, as some are more potent than others.
Pau d’arco dosage
In a study published by HHS Public Access, a daily dose of 1050 milligrams of encapsulated Tabebuia avellanedae bark extract was generally safe and well-tolerated in healthy women experiencing menstrual cramping.
However, there is no standardized recommended dose, and it's best to consult a healthcare professional before incorporating pau d'arco into your routine to minimize the risk of side effects.
Potential downsides of pau d’arco
Pau d'arco is generally considered safe when used appropriately, but it can cause side effects in some people. Reported adverse effects include nausea, vomiting, dizziness, diarrhea, and indigestion.
In severe cases, allergic reactions can occur. Individuals with allergies to plants belonging to the Bignoniaceae family should exercise caution and consult with a healthcare professional before using pau d'arco.
Additionally, large doses of pau d’arco have been shown to slow blood clotting, which could lead to excessive bleeding in individuals taking blood thinners or those with blood-related issues.
Pregnant and breastfeeding women should also avoid using pau d’arco due to insufficient safety data.
Key takeaways
In summary, pau d'arco, derived from the inner bark of the Tabebuia tree, offers numerous potential health advantages due to its rich content of naphthoquinones, phenolic compounds, and antioxidants.
Notable pau d'arco benefits include pain relief, antibacterial and antifungal effects, and immune-enhancing properties while potentially lowering the risk of certain cancers.
While generally safe, pau d'arco may cause side effects and interact with certain medications. Pregnant and nursing women and those with bleeding disorders should consult a healthcare provider before use.
