Palo Azul vs Bacteria


Studies find that palo azul can help treat cavities, E. coli and bad breath

A clinical study tested 47 different plants for the treatment of dental diseases such as toothache, dental caries, periodontal disease and gingivitis. 

As it turns out, palo azul was among the plants that showed the highest inhibitory effect against certain bacterial diseases! For this reason, it was among the plants most frequently used for treating tooth pain, gum diseases, cavities, and bad breath!

Another study even concluded that it “showed good antimicrobial effects in E. coli!” 

How can palo azul protect against bacteria?

The answer is simple: Flavonoids.

Flavonoids are natural products commonly found in vegetables, fruits, plants, bark, flowers, wine and tea such as palo azul.

There’s a ton of studies that have found numerous health benefits in flavonoids and these are are attributed to their anti-oxidative, anti-inflammatory, anti-diabetic, anti-aging, anti-hypertensive, anti-bacterial, anti-mutagenic, anti-viral and anti-carcinogenic properties.

In fact, a medical review that analyzed the results of 161 studies mentioned that flavonoids proved to be potent antimicrobial and viral inhibitors.

Therefore, they are found to be effective against many infectious diseases (bacterial and viral) such as E. coli.

* Here is an interesting finding!

“Flavonoids are known to be synthesized by plants in response to microbial infection; thus it should not be surprising that they have been found in vitro to be effective antimicrobial substances against a wide array of microorganisms.” It’s due to their potent antibacterial, antimicrobial and antiviral activity that flavonoids “show inhibitory activity against E. coli."

A large number of studies have suggested protective effects of flavonoids against many infectious (bacterial and viral) and degenerative diseases such as cardiovascular diseases, cancers and other age-related diseases.

Finally, book about botanical medicine writes the following statement about palo azul:

“Flavonoids have also been recognised for their antimicrobial activity and many researchers have isolated and identified the structures of flavonoids having properties of antifungal, antiviral and antibacterial activity. Because of this property, many flavonoids are now being used extensively in the fields of nutrition, food safety and health.

Below we have outlined the key points from ALL of the research we’ve done and we’ve also cited all of the research literature.

Key findings from medical studies

• One study tested 47 plants and concluded the following: “Our study demonstrated that most of the medicinal plants showed an antibacterial effect in vitro, and justified at least in part their use in traditional medicine.” The same study mentioned that “the most frequent uses were to treat tooth pain, gum diseases, bad breath and cavities.”

• Moreover, this same study found that Eysenhardtia polystachya (palo azul) was among the plants that showed the “highest inhibitory effect against Streptococcus mutans and Porphyromonas gingivalis.”

• Another study found that palo azul “showed good antimicrobial effects in E. coli” and concluded the following: “The results here presented corroborate the folk medicinal use of Eysenhardtia polystachya (palo azul) in the treatment of infections, diarrhea, inflammation, and pain.

• “Flavonoids have also been recognised for their antimicrobial activity and many researchers have isolated and identified the structures of flavonoids having properties of antifungal, antiviral and antibacterial activity.”

• “Flavonoids show activity against several types of virus including HSV, respiratory syncytial virus, polio virus and Sindbis virus.”
