Palo Azul is a favorite in wellness circles for its soothing effects, but it has long been used in folk medicine throughout Mexico City and beyond. It’s more than just pretty to look at, as it’s packed with history and purpose! If you’re curious about why this wood has such a devoted following and what it can offer you, you’re in the right place.
What is Palo Azul?
Palo azul’s name translates to “blue stick” in Spanish. It is derived from the bark of Eysenhardtia polystachya (Mexican kidneywood), a small tree or large shrub that can grow anywhere from 1.5 to 7 meters tall.
It has twisted, slender trunks and branches with feathery, small leaflets arranged along a central stem. Contrary to what others may believe, its bark doesn’t look visibly blue, but brownish-gray. The distinctive blue color only appears when the bark is steeped in hot water and then held up to the light at a right angle.
The tree produces small, white to pale lavender-colored flowers in the spring, which helps attract pollinators. After blooming, palo azul then produces legume-style seed pods.
These flowers and seed pods make it easier to spot Eysenhardtia polystachya in the wild, as it would otherwise look just like other small trees and shrubs in the desert.
Where Does Palo Azul Grow?
It can be found in central and southern Mexico, as well as in areas of the US, such as Texas, Arizona, and New Mexico, where it is native to these states. The tree thrives in a warmer climate with dry, rocky soils and arid conditions. Places that are wet, humid, or cold aren’t suitable for this tree.
Uses of Palo Azul
Palo azul has a rich history of being used as an herbal remedy in folk medicine, where it’s believed to be particularly effective for the kidneys and the bladder. Traditional herbalists often make use of the leaves, bark, and pods of the plant as they are rich in vitamins, minerals, and antioxidants, which are associated with cleansing and calming properties.
Below are the different ways to use parts of the palo azul tree that may benefit your health:
May Support Bladder and Kidney Function
Traditionally, bark and/or leaf infusions from the tree are prepared to support urinary health. These parts of the plant are believed to help flush out toxins, support kidney health, prevent urinary infections, and prevent the formation of kidney stones thanks to their diuretic properties.
Natural compounds like tannins and flavonoids can help soothe the bladder and urinary tract, reducing the frequency and urgency of urination, and even prevent the growth of crystals in the kidneys before they start.
The diuretic properties of palo azul make it popular among individuals seeking weight loss or gentle detoxification. It’s worth noting, however, that claims of rapid weight loss through this herbal tea should be approached with caution. Any form of weight management should be combined with healthy lifestyle changes for the results to last.
Helps Reduce Inflammation
The tree bark contains flavonoids, which have anti-inflammatory effects and can also help reduce oxidative stress. Bark extracts in traditional medicine are used to help ease joint pain, stiffness, swelling, and symptoms of rheumatoid arthritis.
Acts as Digestive Support
Some use parts of the tree to support digestive health. Teas made from the bark may help soothe the digestive tract and relieve bloating and digestive discomfort. Some studies suggest that it can be as effective as loperamide in treating or managing diarrhea, although further research is needed to support this claim.
Regulate Blood Sugar Levels
Using this herbal medicine may also be beneficial in blood sugar regulation. The flavonoids and antioxidants in the palo azul tree can be helpful for individuals with insulin sensitivity and insulin resistance, as they help lower blood glucose levels. However, proper evaluation of antidiabetic effects still needs to be conducted to confirm this effect.
Treatment of Oral Cavity Infections
The antimicrobial compounds in the plant may also help treat oral bacterial diseases. Historically, the bark has been used to make a rinse to help reduce gum inflammation and support oral hygiene.
Helps with Gout
Since the use of palo azul bark and leaves helps prevent fluid retention, it may also aid in reducing uric acid levels in the body. This is especially helpful for those suffering from gout or joint flare-ups and inflammation.
How to Use Palo Azul
The best way to enjoy the tree’s benefits is by drinking palo azul tea, which you can prepare using loose bark or commercially available tea bags. Here’s how to prepare it:
- Boil about one ounce (about 28 grams) of tree bark in one gallon of water in a pot.
- Let it simmer for 20-30 minutes, or until the water changes to a bluish-brown hue.
- Let the tea cool for a bit before straining it to remove any debris.
- Pour the tea into a cup and drink hot or cold. You can add lemon, honey, or cinnamon to enhance its earthy flavor if desired.
- Store any leftovers in the fridge for up to a week.
Considerations and Safety Precautions Before Using
Many of the perceived benefits of palo azul are based on historical use and anecdotal evidence. While it’s generally considered safe to consume parts of the tree in moderation, here are a few things to keep in mind:
- Not a miracle cure. Although it offers some health benefits, it should not be relied upon solely for treating chronic diseases such as diabetes or kidney disease.
- May interact with medications. Consuming this herbal remedy may affect how medications are absorbed or eliminated by the body.
- Don’t drink the tea when pregnant or breastfeeding. It’s best to avoid consuming the tea if you’re pregnant or breastfeeding, since there is limited research conducted on its safety.
- Always consult a healthcare provider. If you’re unsure, consult your doctor before incorporating this natural remedy into your health routine.
