Benefits & Side Effects of Palo Azul Tea

Palo Azul tea is a popular South American beverage, but its unique nutritional profile and health benefits have caused it to rise in popularity in recent years in other parts of the world as well.

What is Palo Azul Tea?

Palo Azul tea is an herbal diuretic tea brewed with the bark of the Palo Azul plant, scientifically known as Eysenhardtia polystachya. Also known as kidneywood, this herb has been used in traditional medicine for thousands of years, and the bark is known to contain some very unique nutrients. When you purchase Palo Azul, it typically comes in the form of wood chips of the bark, which you can then steep in the water to release the flavonoids, sterols, and phenolic compounds contained in this powerful plant. These active ingredients can have a range of effects in the body, but this tea is particularly well known for its hepatoprotective effects, meaning it protects the liver so it can properly detoxify the body. In recent years, it has become very popular for those who need to pass drug tests, likely due to its diuretic effects flushing out metabolites from certain recreational drugs, such as marijuana.

The possible primary benefits of Palo Azul tea include the following:

  • Protecting kidney health
  • Reducing inflammation
  • Weight loss
  • Treating digestive upset
  • Preventing chronic diseases
  • Improving mental health

Let’s look at the benefits in detail below:

Might Help In Kidney Health

The primary use of Palo Azul tea throughout history has been to strengthen and protect the body’s natural detoxification systems. Results from a study published in Pharmacognosy Magazine indicate that this tea might prevent oxidative stress, suppressing kidney and pancreas cell damage. This tea may also lower your risk of kidney stones, promote healthy urination and the rapid expulsion of toxins metabolites from the body. [6] [7] [8]

May Reduce Inflammation and Arthritic Pain

The active components of this tea are known to possibly minimize the pain and discomfort of arthritis, as well as other inflammatory conditions, such as gout. Another study published in the African Journal of Pharmacy and Pharmacology showed that Palo Azul tea may even be effective in treating both chronic and acute inflammation, and effectively reduced edema (swelling) in inflamed areas. [9] [10]

Can Help Treating Digestive Upset

The incredible calming anti-inflammatory properties of Palo Azul tea extend to the digestive system as well. A 2018 study published in the Journal of Ethnopharmacology indicates that this tea is an effective anti-diarrheal agent; just as effective as standard drugs. [11]

May Help In Weight Loss

A study published in Pharmacognosy Magazine showed promising effects on body weight in animal models. Mice receiving Eysenhardtia polysachya showed a significant reduction in not only body weight, but also blood glucose, triglycerides, and cholesterol. The mechanism for this weight loss effect is not well understood, though it may be partially due to the plant’s diuretic effects. Further studies are needed to better explore the use of this tea as a potential weight loss aid. [12]

Can Aid In Preventing Chronic Disease

Oxidative stress is associated with many chronic diseases like diabetes. Compounds within the tea show high antioxidant and free radical scavenging activity, which may potentially help protect against these conditions. Palo Azul tea may also be especially an effective and protective agent for diabetes. The tea inhibits high blood sugar, high cholesterol and protects the liver, all of which is important in helping to prevent various complications of diabetes. [13]

The tea's color alters as you cook it. It transitions through a variety of shades of brown, red, and blue. If you want the color of the tea to be bluer, you can cook it for half an hour. Moreover, the blue color is merely seen as a refraction of light. If you wish to have an even more intense shade of blue, pour the tea in a clear water bottle or glass and hold it near the light. This will help you see the blue hues of the tea. 

Palo Azul Tea Side Effects

There are very few side effects associated with Palo Azul tea, and there are no reported cases of toxicity. However, some people do experience gastrointestinal distress, and this tea is not recommended for pregnant or nursing women, given the lack of solid research on its potential impacts.
