Nyarkotey Tea : The New Innovative Cardiovascular Health and General Wellbeing Product

Nyarkotey Tea : The New Innovative Cardiovascular Health  and General Wellbeing Product

What is Nyarkotey Tea?

Nyarkotey Tea is a clinical grade, advanced, comprehensive phytomedicine product approved by the FDA for Cardiovascular Health and general wellbeing. Nyarkotey Tea is also designed to help guard against Cardiovascular Health and general wellbeing. The Nyarkotey Tea made with concentrated bioenergized Hibiscus Sabdariffa is termed as ‘Heart insurance Tea”

Lab study conducted in Ghana on efficacy showed the product Dr. Nyarkotey Herbal Tea produced dose-dependent reduction in the arterial blood pressure of the anaesthetized cat comparable to acetylcholine. The depressor effects of acetylcholine and Dr. Nyarkotey Herbal tea on the blood pressure of the anaesthetized cat were inhibited by 72.3+5.21% and 55.6 + 6.82% respectively, suggestive of muscarinic mediation.

The remarks states that, as per the findings, Dr. Nyarkotey Herbal Tea has hypotension effect and hence could be used in the management of hypertension. The No-Observable-Adverse-Effect level (OAEL) is greater than five times the stated daily dosage (7.0ml/kg) indicated by the manufacturer. The recommended daily dose is thus within the acceptable margin of safety. Human clinical trials also conducted by Dr. Chris Cole, MD in Niamey, Niger and his team to assess it effectivity also confirmed quality of life improvement for Hypertensive and Diabetic Patients.

The mechanisms for how hibiscus produces these benefits to blood pressure is revealed in the research by Obiefuna P et al 1994. According to the paper, hibiscus increases the ability of blood vessels to relax (called “vasodilation”) Obiefuna P et al 1994 and also affects a frequent target of blood pressure medications, an enzyme in the kidney called angiotensin-converting enzyme(Herrera-Arellano et al 2004 and Nwachukwu DC et al 2015.

Nyarkotey Tea formulated with concentrated Hibiscus Research:

Hibiscus Sabdariffa

The Prostate.Net described the Hibiscus Tea as the best tea for Men’s Health. The most important thing about the hibiscus sabdariffa in tea form is that it is one of the richest sources of antioxidants to be used in a beverage. This was revealed in a study published in Nutrition Journal where the investigators elucidated how they developed a comprehensive food database that listed the antioxidant content of more than 3,100 foods, spices, beverages, herbs, and supplements. After analyzing 283 different beverages, hibiscus tea beat matcha green tea when it came to antioxidant content. While green tea is still a very good beverage choice for antioxidants, hibiscus tea tops the list (Carlsen et al 2010).

Both green tea and hibiscus tea are among the top drinks for prostate health. Both types of tea contain potent antioxidants. Studies show that green tea can help prevent prostate cancer from forming and may also slow the growth of aggressive prostate cancer. Studies show that green tea can also benefit men with BPH and prostatitis. Chun-Tang Chiu et al 2015 research demonstrated the effect of hibiscus tea to reduced invasiveness of the cancer cells.

Hibiscus tea has also been shown to work as a natural diuretic in a research by Allison L. Hopkins et al 2013 , increasing both urination and bowel movements. Hibiscus also crushed kidney stones by increasing the flow of water through the kidneys, the concentration of oxalate and other stone forming substances is decreased, and instead of adding to the crystals in the kidneys, watery urine helps dissolve them. This process is not quick enough for most people, but hydration is very important for kidney stones.

As the water leaves the body, it pulls the sodium with it, which is one mechanism by which blood pressure is reduced. As mentioned above, hibiscus tea contains a rich amount of anthocyanin, which is a phenolic compound. It is believed that this active compound is responsible for the tea’s cardio-protective effects.

While the blood pressure-lowering effects of hibiscus have been demonstrated in humans in 2004(Herrera-Arellano et al ), 2010(McKay DL et al) , and 2015 (Nwachukwu D et al studies, a 2017 study(Nwachukwu DC et al) has shown that hibiscus not only helps maintain a healthier blood pressure, but it does not harm kidney function. This was also demonstrated in the lab study at Kwame Nkrumah University of Science Technology where our product sent for analysis proved no harm on the kidneys in 2016. Kidney function can be harmed by high blood pressure (Bigazzi R et al 1992) , so it’s important that treatments for high blood pressure do not cause further harm to kidney function.

The 2017 study by Nwachukwu DC et al involved 78 subjects (45 men, 33 women) aged 43 to 53 who were recently diagnosed with mild hypertension (as defined as by the Guidelines Subcommittee WHO. 1999 World Health Organization – International Society of Hypertension Guidelines for the Management of Hypertension. 1999:151-183. ) but had not yet started any medical treatment. They were divided into three groups for 4 weeks:

i. Hibiscus (26 subjects): 150 milligrams per kilogram of bodyweight of hibiscus in a drink as prepared in previous studies by Herrera-Arellano et al 2004 . This provided about 10 milligrams of anthoycyanins per day.

ii. Medical treatment (26 subjects): 10 milligrams lisinopril per day

iii. Placebo (control group = 26 subjects)

Before and after the study, diastolic and systolic blood pressure was measured and urine samples were taken to measure kidney function. After 4 weeks, researchers noted the following changes in blood pressure, with Hibiscus not only reaching statistical significance versus placebo (p < 0.001) but also the same statistical significance versus Lisinopril (p < 0.001):

Urine Vol Hibiscus Lisinopril Placebo p-value

( mL) 64% increase 37% increase 1.8% increase < 0.001

(1250 to 2050) (1240 to 1700) (1375 to 1400)

Creatinine Clearance 7.9% increase 5% increase 1% decrease < 0.001

(mL/min) (101 to 109) (100 to 105) (102 to 101)

Regarding kidney function, researchers assessed two overall measures of kidney function, creatinine clearance and urine volume over a 24-hour period(Boron WF et al 2009) . Hibiscus again reached statistical significance versus both placebo (p < 0.001) and Lisinopril (p < 0.001):

Diastolic blood

Pressure Hibiscus Lisinopril Placebo p value

(mmHg) 12.2% decrease 9% decrease 1.1% decrease < 0.01

(99 to 87) (100 to 91) (99 to 98)

Systolic blood pressure 11.1% decrease 8% decrease 0.7% decrease < 0.01

(mmHg) (154 to 137) ( 151 to 139) (153 to 152)

When suggesting mechanisms for how hibiscus produces these benefits to blood pressure, the researchers cited research showing that hibiscus increases the ability of blood vessels to relax (called “vasodilation”) Obiefuna P et al 1994 and also affects a frequent target of blood pressure medications, an enzyme in the kidney called angiotensin-converting enzyme(Herrera-Arellano et al 2004 and Nwachukwu DC et al 2015.

Although a weakness in this study was the homogenous population studied, the researchers concluded that “Consumption of hibiscus with a standardized amount of 10.04 mg anthocyanins improved renal function in patients with mild to moderate hypertension, with better effects than lisinopril”. They added that “Further research is required to explore the possibility of utilizing our important finding and integrating it into our National Health Care Program since hibiscus is easily available and affordable in Nigeria.”

A 2012 Tufts University study published in the Journal of Nutrition reported that hibiscus tea demonstrated promising results when pitted against placebo tea. In the double-blind, placebo-controlled study, 65 adults with prehypertension or mild hypertension were given either three 240-mL servings of either hibiscus or placebo tea daily for six weeks.

At the end of six weeks, adults who had consumed the hibiscus tea had a lower systolic blood pressure when compared with adults in the placebo group, but the same was not true for diastolic pressure. The authors concluded that “daily consumption of hibiscus tea…lowers BP in pre- and mildly hypertensive adults and may prove an effective component of the dietary changes recommended for people with these conditions.”

The healthful benefits of hibiscus don’t end there. Another study explored the impact of hibiscus extract powder in patients with metabolic syndrome. Metabolic syndrome is a combination of disorders that increase a person’s risk of developing diabetes and cardiovascular disease. Components of metabolic syndrome include insulin resistance, obesity, high blood pressure, elevated triglycerides, and low “good” cholesterol (high-density lipoprotein, HDL).

The study evaluated the effects of Hibiscus sabdariffa extract powder on people with and without metabolic syndrome. All the participants took 100-mg capsules of hibiscus extract daily for one month. At the end of the month, individuals with metabolic syndrome showed significantly lower levels of glucose and total cholesterol as well as an in increase in HDL levels. Hibiscus extract also lowered triglyceride levels in people with and without metabolic syndrome.

Analysis of Hibiscus Tea on ED

Remember that erections are all about your arteries - nitric oxide in your arteries and nice low blood pressure levels (which indicates higher blood flow):

1. Increased eNOS Activity and Nitric Oxide. We get most of our arterial nitric oxide from the endothelium and this is governed by the eNOS enzyme. It turns out that the polyphenols in hibiscus tea activate this enzyme and cause your endothelium to produce more nitric oxide.

Well, one would say ", this is animal study in the lab and not in actual human subjects." You are correct though. Nevertheless, one of the big tests for any possible NO-increasing compounds is whether or not it can produce big drops in blood pressure. In this article I have reviewed research papers on this, this has been demonstrated in at least five studies, three of which I have acknowledged below.

Also, I do not need to point out that boosting arterial nitric oxide, which is the center of attention in this article, will largely help significantly with mild to moderate erectile dysfunction. Not promising you that it will solve it, but you have nothing to lose.

2. Endothelial Function. This formula explains this:

Erectile function = Endothelial function

The endothelium is the thin layer of cells on the inside of your arteries that are responsible for controlling their expansion and contraction and the nitric oxide that governs the process. Researchers refer to this ability to relax the arteries as "endothelial function," and, generally speaking, endothelial function governs how well and how fast your erections are. (There are exceptions, of course, as low dopamine, venous leakage and other systems can negatively impact erections as well.) In any event, you can probably guess where I am headed: hibiscus tea has been shown to significantly help with endothelial function:

"Diuresis and inhibition of the angiotensin I-converting enzyme were found to be less important mechanisms than those related to the antioxidant, anti-inflammatory, and endothelium-dependent effects to explain the beneficial actions. Notably, polyphenols induced a favorable endothelial response that should be considered in the management of metabolic cardiovascular risks."

Notice that these researchers boldly told physicians to consider using hibiscus in their practices. But how many physicians actually consider natural solutions to chronic disease, even though 99% of the time, chronic disease results from unnatural lifestyles?

Again, an improvement in endothelial function will help the solid majority of men with mild to moderate erectile dysfunction. This is especially true if coupled with a high nitric oxide-based lifestyle.

3. Hypertensive Type II (Adult Onset) Diabetics. This study did a black tea versus hibiscus tea study. (Black tea is known for also improving endothelial function, although this study found the opposite.) The results were very impressive for hibiscus tea:

The mean of systolic BP (SBP) in the ST [hibiscus tea] group decreased from 134.4 11.8 mm Hg at the beginning of the study to 112.7 5.7 mm Hg after 1 month, whereas this measure changed from 118.6 14.9 to 127.3 8.7 mm Hg in the BT group during the same period."

A 20+ point drop in systolic blood pressure should get everyone's attention. Of course, this means that the participants arteries relaxed or dilated and blood flow increased.

Admittedly, the number of patients was small (60) and another study found that black tea decreased blood flow in a dose dependent manner instead of restricting it.

4. Moderate Essential Hypertension. Patients with essential are often the toughest to treat, because they have no known cause. In a small study, hibiscus provided solid results in just this situation:

127201970548 0g730m4yxs image004

"Statistical findings showed an 11.2% lowering of the systolic blood pressure and a 10.7% decrease of diastolic pressure in the experimental group 12 days after beginning the treatment, as compared with the first day. The difference between the systolic blood pressures of the two groups was significant, as was the difference of the diastolic pressures of the two groups. Three days after stopping the treatment, systolic blood pressure was elevated by 7.9%, and diastolic pressure was elevated by 5.6% in the experimental and control groups."

5. Prehypertion and Mild Hypertension. Again, this was a fairly small study (65 participants) but provided solid results:

"A standardized method was used to measure BP at baseline and weekly intervals. At 6 wk, hibiscus tea lowered systolic BP (SBP) compared with placebo (-7.2 11.4 vs. -1.3 10.0 mm Hg). Diastolic BP was also lower, although this change did not differ from placebo (-3.1 7.0 vs. -0.5 7.5 mm Hg)." This group is particularly relevant in my opinion, because we clearly have quite a few prediabetic men on the Peak Testosterone Forum.

6. Protection Against Arterial Plaque. One thing that can lower your nitric oxide and endothelial function over time is a buildup in plaque in your arteries. Why? Because plaque represents actual damage and "scarring" of the lining of your arteries. Keep in mind that blood supplied to your penis is done so via the pudendal artery and you have actual penile arteries as well. Things simply are not going to work right in the bedroom if you have significant atherosclerosis.

Meta-Analysis.All I can say for what these researchers concluded:

"Results Four trials, with a total of 390 patients, met our inclusion criteria. Two studies compared Hibiscus sabdariffa to black tea; one study compared it to captopril and one to lisinopril. The studies found that Hibiscus had greater blood pressure reduction than tea but less than the ACE-inhibitors. However, all studies, except one, were short term and of poor quality with a Jadad scoring of <3 and did not meet international standards. Conclusion .The four randomized controlled studies identified in this review do not provide reliable evidence to support recommending Hibiscus sabdariffa for the treatment of primary hypertension in adults."

The authors above know that no one except large pharmaceutical companies can afford massive, large scale trials. So, sure, it's obvious that hibiscus tea has not been held up to FDA-style scrutiny, and it never will. But it's been a solid performer in multiple studies on multiple subpopulations.

Hibiscus tea provides solid results for increasing blood flow and lowering blood pressure and should be considered by men with erectile dysfunction as a potential significant help. It should also be consumed regularly to help prevent atherosclerosis. Get Nyarkotey Tea for your cardiovascular Health.
