Here’s another fun fact…Due to its popularity as a diuretic, palo azul is commonly used by people as a means to clean out their system in order to pass drug tests.
In fact...In fact, diuretics are so powerful in cleansing the body, that in 1988 they were banned by the World Anti-Doping Agency because athletes were using them to detoxify their bodies and pass drug tests!
How can diuretics help you?
Alleviate kidney pain and reduce kidney stone growth
Due to the popularity of palo azul’s diuretic property, many studies have evaluated its diuretic activity and its efficacy for treating kidney pain, urinary tract pain, and kidney stones.
Various studies have found that palo azul shows effective diuretic & antibacterial activity and therefore, it significantly reduces kidney stone growth and alleviates kidney & urinary tract pain.
In fact...6 different studies found that Palo Azul prevented the formation of kidney stones (calcium oxalate crystals) and significantly decreased the size of kidney stones. Therefore, one study concluded that it can be "recommended as a preventive medication in the formation of kidney stones.”
But that's not all! Another study found that "flavonones in Palo Azul have been identified with antibacterial and antifungal activity.” Therefore, it could be used for “kidney problems, urinary tract pain, kidney calculi, and as a deflamatory."

Palo Azul's diuretic property is also effective in treating urinary tract pain, because it increases urinary flow.
The results of 4 different studies suggest that Palo Azul can reduce irritability in the urinary tract.
In addition, the methanolic extracts of Palo Azul were effective against bacteria which are “the most frequent causal agents of urinary tract infection.”

A book about botanical medicine writes the following statement about palo azul:
“If prone to acidic, overly concentrated urine, associated kidney stones and urinary tract sediment then Kidneywood (palo azul) will be of use. Because of the plant’s alkalinizing nature, acidic precipitants dissolve back into the urine, thereby reducing pain and urinary tract irritability associated with lithic deposits. Kidney wood (palo azul) is soothing to kidney and urinary tract irritability.”
Below we have outlined the key findings from ALL of the research we’ve done and we’ve also cited all of the research literature.
Enjoy! :)

Key findings about kidney pain
• One particular study revealed that the aqueous extract of E. polystachya (Palo Azul) "induced an important diuretic activity" because increases in urinary flow and urinary sodium excretion were observed.
• Researchers from one study found that “isoflavones in Palo Azul stopped the formation of calcium oxalate crystal growth in rats. They also concluded that “you can take Palo Azul as a preventative measure to avoid kidney stone growth.”
• Another study stated that isoflavones from Palo Azul “significantly lower(ed) growth rate and nucleation rate of calcium oxalate crystals” and “work as inhibitors in the formation and crystal growth of COM and phosphate and may protect against stone formation by reducing the degree of aggregation and the size of particles precipitated.”
Key points about urinary tract pain
• “Due to the alkalinizing nature of this plant, acidic precipitants dissolve back into the urine, thus reducing pain and irritability of the urinary tract.”
• “The bark of E. polystachya (Palo Azul) induces an increase on urinary excretion of water and sodium, similar to furosemide, but with the advantage of a potassium-saving effect. These findings support the claims of diuretic efficacy of the bark of E. polystachya (Palo Azul) in the Mexican Traditional Medicine.”
Medical Studies
* Palo Azul is commonly referred to by its scientific name: Eysenhardtia polystachya / E. polystachya / E.P - Cyclolepis genistoides / C. genistoides - kidney wood - palo dulce
The isoflavones isolated from heartwood of Eysenhardtia polystachya: 7-hydroxy-2’, 4’, 5’-trimethoxyisoflavone [A] y 7-hydroxy-4’-etoxyisoflavone [B] showed significant dose dependent protection against urolithiasis induced by zinc disc implantation in albino rats. The change of oxalate concentration in urines normal, abnormal and artificial treated with isoflavone [A] was reduced in 64.23, 38.6 y 22.43% respectively. When the compound [B] was added reduced in 55.95, 18.62 y 20.32% respectively. The activity of compounds [A] on the formation of phosphate for normal abnormal and artificial urines were of 70.31, 44.57 y 38.61% respectively. With the added of compound [B] were reduced in 63.8, 40.61 y 30.16% respectively. The compounds [A] and [B] produced significantly lowering growth rate and nucleation rate of calcium oxalate crystals at concentration of 4.6 X 10-4 M exerted a maximum response of 89% and 72% reduction respectively.
Conclusion: The isolated isoflavones [A] and [B] from E. polystachya work as inhibitors in the formation and crystal growth of COM and phosphate and may protect against stone formation by reducing the degree of aggregation and the size of particles precipitated. These compounds can be recomended as a preventive medicine in renal stone formation.
(Jan 21, 2016) Diuretic activity of the bark of Eysenhardtia polystachya
The present results reveal that E. polystachya aqueous extract (500 and 750 mg/kg) induced an important diuretic action because increments in the urinary flow and urinary excretion of sodium similar to furosemide were shown.
The bark of E. polystachya induces an increase on urinary excretion of water and sodium, similar to furosemide, but with the advantage of a potassium-saving effect. These findings support the claims of diuretic efficacy of the bark of E. polystachya (Palo Azul) in Mexican Traditional Medicine.
If prone to acidic, overly concentrated urine, associated kidney stones and urinary tract sediment then Kidneywood (palo azul) will be of use. Because of the plant’s alkalinizing nature, acidic precipitants dissolve back into the urine, thereby reducing pain and urinary tract irritability associated with lithic deposits. Kidney wood is soothing to kidney and urinary tract irritability.
The results of this study are as follows. The following flavonoids have been found (in Palo Azul): dimethoxy-methylenedioxy-pterocarpan and dehydrorotenone, sterol betasistosterol, triterpene beta-amirine, flavonoids coatline A and B and coumarin flemichaparin (12) have been found.
These flavonones have been identified with antibacterial and antifungal activity. Recent studies have "evaluated the effect of isoflavones isolated from the bark of Eysenhardtia Polystachia( blue stick) on the growth of urinary crystals confirming the use of the plant in urolitasis (25).”The infusion or decoction is used for kidney problems, urinary tract pains, kidney calculi, and as deflamatory. Eysenhardtia Polystachia (Palo Azul) according to the results of the study etnobotanico Eysenhardtia Polystachia (Palo Azul) is a plant used mainly to treat kidney disease.
Polystachya is a tree used widely in traditional Mexican medicine as a herbal remedy and is native to north-eastern Mexico, especially in the Nuevo Leon and Tamaulipas states. The E. texana tree is also known as kidneywood because of its use for kidney and bladder complaints. This tree is distributed throughout south-central USA and northern and central Mexico. The aim of the present study is to evaluate the antimicrobial activity of methanolic extracts of E. polystachya and E. texana against nine species of bacteria and one species of yeast related to urinary tract infections.
Methanolic extracts of Eysenhardtia polystachya and E. texana were active against S. epidermidis (mean inhibition: 1.75 cm for both extracts). In addition, E. polystachya was active against Proteus vulgaris (mean inhibition: 1.75 cm), Enterbacter aerogenes (mean inhibition: 1.75 cm) and S. aureus (mean inhibition: 1.25 cm). The bacteria included in this study are the most frequent causal agents of urinary tract infection.
Conclusion: According to the results of this study, methanolic extract of E. polystachya has broad-spectrum effect because the antibacterial activity observed included both Gram-positive and Gram-negative organisms.
Based on these results, the isolation and characterisation of active compounds from E. polystachya is particularly important in light of the multidrug resistance observed in certain Gram-positive and Gram-negative bacteria,12,13 against which only a few therapeutic options are available.
In this study was evaluated the inhibitory effect of 7-hydroxy-2′,4′,5′-trime-thoxyisoflavone (1) and 7-hydroxy-4′-ethoxyisoflavone (2) isolated from bark of E. polystachya on aggregation calcium oxalate crystals in two different assay with a non-crystal-seed system.
Both isoflavones showed a marked inhibitory activity on crystal aggregation on urine non-stone-formers, whereas in urine from recurrent stone-formers and simulated orine showed less inhibitory activity compared to normal urine.
Conclusion: Also the effect of the isoflavones (1) and (2) on crystal growth of calcium oxalate (COM) at conditions of constant solution supersaturation was determined. The isolated isoflavones 7-hydroxy-2′,4′,5′-trimethoxyisoflavone and 7-hydroxy-4′-ethoxyisoflavone from E. polystacha work as inhibitors in the formation and crystal growth of calcium oxalate, reduced the degree of aggregation and the size of particles precipitated.
(Jan-May, 2007) Herbal Drugs in Urolithiasis - A Review
The present review aims to give data highlighting the present trends in research of medicinal plants accredited with antiurolithiatic activity.
Antiurolithiatic activitiy of two compounds viz., 7-hydroxy2',4’,5'-trimethoxyisoflavone and 7-hydroxy-4'-methoxy isoflavone isolated from the heart wood of Eysenhardtia polystachya was studied in rats by observing calculus formation experimentally induced by zinc discs. A significant decrease in urinary stone size was observed in animals treated with these compounds (23).
Conclusion: As the present review illustrates, a number of medicinal plants are evaluated mainly against calcium oxalate and magnesium ammonium phosphate types of kidney stones, employing various experimental models of urolithiasis. Further, chemical studies of the plants are needed to isolate the active principles and investigate them in order to identify a promising lead compound. Currently, in the management of urinary stones surgical procedures and extra corporeal shock wave lithotripsy are commonly employed. The major drawback of these procedures is recurrence of stones. The plant products and derivatives of their lead compounds as such may not replace these procedures but may surely help in decreasing the recurrence rate of renal calculi.
(Dec 18, 1998) Antiurolithiatic activity of Eysenhardtia polystachya aqueous extract on rats
The aqueous extract of the bark of Eysenhardtia polystachya was tested for its antilithiatic and diuretic activity. The urolithiasis was induced experimentally by implantation of a zinc disc in to the urinary bladder of rats. A significant decrease in the weight of stones was observed after treatment in animals that received aqueous extract compared with control groups. This extract showed an increase in the 24 h urine volume compared with the control. © 1998 John Wiley & Sons, Ltd.
Medical study of Urology College of Mexico with collaboration of Universidad Autónoma Metropolitana-Xochimilco
Another study looked at how isoflavones (a crystalline compound found in plants) from Palo Azul protected against kidney stones. They were looking to see if the isoflavones could stop the creation of calcium oxalate (the medical name for the most common type of kidney stones). They found that the isolated isoflavones in Palo Azul stopped the formation of calcium oxalate crystal growth in rats. They also put in their conclusion that you can take Palo Azul as a preventative measure to avoid kidney stone growth. This research was done by the Urology College of Mexico with collaboration with Universidad Autónoma Metropolitana-Xochimilco
