Antioxidants vs Hypertension
On top of all the other beneficial properties of palo azul, this magical tea also has one of the most well studied and healthful compounds in the world. Flavonoids! Flavonoids are antioxidant compounds which are found in fruits, vegetables, green tea, etc.
You’ve probably heard of the antioxidant health benefits of green tea and how they can help you lose weight, lower blood pressure, lower cholesterol, reduce the risk of diseases, etc. Many studies have attributed these beneficial effects from green tea to flavonoids in green tea (catechins).
We read two medical reviews composed of findings from 327 different studies conducted specifically on flavonoids, and their findings revealed that "dietary flavonoids are associated with a lower risk of hypertension and CVD (cardiovascular disease).”
The scientists who published these reviews also observed that “the blood pressure level was reduced in patients with hypertension” after greater consumption of flavonoids.
Scientists in one study observed the “consumption of them (flavonoids) is associated with improvement in endothelial function (blockage of arteries) via vascular endothelial nitric oxide synthase and protein kinase B (Akt) activation.”
What is endothelial function?
The endothelium is a thin membrane that lines the inside of the heart and blood vessels. Endothelial cells release substances that control vascular relaxation and contraction, as well as enzymes that control blood clotting, immune function, and platelet adhesion.
Endothelial dysfunction has been shown to be important in predicting stroke and heart attacks due to the inability of the arteries to dilate completely. Dysfunction can result from high blood pressure, diabetes, high cholesterol, and smoking.
Studies have shown that endothelial dysfunction precedes the development of atherosclerosis, a chronic disease characterized by abnormal thickening and hardening of the artery walls. This can cause a stroke or a heart attack.
In other words...Endothelial dysfunction causes a blockage in the arteries that can lead to hypertension, stroke, or heart attack.
These are the most flavonoid-rich foods: apples, pears, onions, strawberries, blueberries, celery, peppers, and teas such as palo azul
Lastly, various epidemiological studies concluded the following:
Flavonoids in tea may “lower blood cholesterol concentrations and blood pressure, thereby providing some protection against cardiovascular disease.”
This is why you should be eating vegetables, fruits and drinking green tea or palo azul tea every day! Below, we have summarized the key points of the studies we reviewed.
P.S...Don't keep this to yourself, share these tips with your loved ones!
Key findings from medical studies
“It was observed that the blood pressure level was reduced in patients with hypertension(,90).”
• “The observational studies done by Hügel et al.(,89) indicated that dietary flavonoids are associated with a decreased risk of hypertension and CVD.”
• “A diet rich in all flavonoid classes through herbs and beverages improves vascular health leading to a reduced risk of diseases.”
“Flavonoids can prevent injury caused by free radicals in various ways and one way is the direct scavenging of free radicals. This action protects the LDL particles and, theoretically, flavonoids may have preventive action against atherosclerosis.”
• “They have miscellaneous favourable biochemical and antioxidant effects associated with various diseases such as cancer, Alzheimer's disease (AD), atherosclerosis, etc.“
• An “antihypertensive effect has been observed in total flavonoid fractions.”
* Palo Azul is commonly referred to by its scientific name: Eysenhardtia polystachya / E. polystachya / E.P - Cyclolepis genistoides / C. genistoides - kidney wood - palo dulce
