Hibiscus and its effect on blood sugar levels, blood pressure and cholesterol : Scientific studies
Hibiscus, scientifically known as Hibisgus Sabdari, is a perennial shrub that includes over 200 species of plants with a wide and spectacular variety of colors, growing in warm, tropical and sub-tropical climates. It is the national flower of Haiti, Malaysia and South Korea, and many around the world use the various parts of the plant in a variety of dishes, beverages and especially in tea brews. Beyond its good taste, drinking an herbal brew with the hibiscus plant may also have positive health outcomes.
Drinking a hibiscus plant brew was tested in a study published in the Phytotherapy Research. This study is a meta-analysis, i.e., a statistical analysis that integrates data from a number of previous independent studies in order to draw a broader and more certain conclusion from them. The study examined the effect of drinking an hibiscus brew on blood lipid profile, fasting blood sugar and blood pressure, in 7 clinical studies that included a total of 362 subjects. The findings of the study showed that the hibiscus treatment caused a substantial and statistically significant decrease in sugar levels and systolic and diastolic blood pressure. In addition, the findings showed that the hibiscus treatment brought about a large decrease in LDL (low-density lipoprotein) values known as "bad cholesterol", although this effect was not statistically significant. Based on these findings, the researchers concluded that hibiscus consumption has a beneficial effect in controlling blood sugar levels and blood pressure values. 
Another study published in the journal Fitoterapia reviewed findings from controlled clinical trials that examined the effect of the hibiscus plant on a wide range of risk factors associated with cardiovascular disease. First, the researchers found that the hibiscus leaves are used in at least 10 countries around the world with no evidence of side effects. Second, findings from randomized controlled trials show that hibiscus treatment lowers systolic and diastolic blood pressure levels in people with hypertension. Third, in more than half of the randomized controlled trials, hibiscus leaves were also found to be effective in lowering bad cholesterol (LDL) and triglyceride levels, and in raising good cholesterol (HDL) levels. The most common explanation for these effects of the hibiscus plant is that it acts as an antioxidant and reduces the oxidation of bad cholesterol. Based on all of these findings, the researchers concluded that the hibiscus plant is a promising treatment for high blood pressure and cholesterol levels and encouraged further research on the subject.

My husband suffers from a high cholesterol problem which is accompanied by fatigue and weakness. Furthermore, the results of other blood tests were not encouraging. Since he started using the "Cholesteren Tea" brew, his wellness has improved miraculously. In addition, there was a considerable improvement in his mood. The Blood results were also improved. I highly recommend using the brew. Thank you from the bottom of my heart for the wonderful products of “Nufar” company.
Hello, I must thank you for the product you developed, "Cholesteren Tea".
To my great surprise the use of the above mentioned tea for two weeks + a certain diet, decreased my cholesterol in general from 254 to 187 and primarily decreased the LDL, which is the problematic component, from 180 to 120. The product solved a very difficult problem of mine, since I cannot get any statins and the doctors were uncertain about how to help me and reduce my bad cholesterol, and here – help has arrived from an unexpected source. Thank you.
My name is Miriam Kochav and I work in alternative medicine in a wide range of fields for about 20 years. I first met with your tea at the "Mother Earth" nature shop in Haifa, where I was advised to try to give it to patients.
I first bought the "Glucoden" tea and distributed it among my patients for the purpose of an experiment, to observe its effect. My patients tasted it and of course purchased it at the nature shop. After about a month, my patients reported back their blood test results showing that their blood sugar levels were decreased. Even those who did not have a sugar problem, drank the tea after their main daily meal and reported about a feeling of relief after the meal.
Next I tried the "Cholesteren" Tea. Of course, not immediately, but after a period of about two months I have been told about a decrease in cholesterol levels, and this, of course, conditional on proper nutrition and a healthy lifestyle.
Now I am trying the product "Nufar Fibers" for a healthy lifestyle and to reach the desired weight, and I hope they will be as wonderful as all your products. It feels that you are putting your heart and soul into them, so that the public will be able to enjoy from super foods and products.
In gratitude and many thanks,
Following high blood cholesterol results, I was looking for a natural solution to the issue. A homeopath recommended me to use your product. Before using the tea my cholesterol level was 360. After ten days of using the tea my cholesterol level decreased to 260.
Dear Nufar company,
Thank you for the Cholesteren Tea product. I used it for about a month and a half, and to my great surprise in the blood tests I saw that my cholesterol levels decreased from 256 to 197, and especially the bad cholesterol, LDL, to 107.
I highly recommend using Cholesteren Tea.

Dear Nufar natural Products
I am Shimon Malka, 64-years old. A few years ago, I was diagnosed with hypertension, borderline diabetes and an enlarged prostate.
I was exposed to Nufar products following my wife who was diagnosed with borderline cholesterol and started treatment with Nufar's Cholesteren (tea brew, twice a day). When she repeated the blood tests it turned out that the bad cholesterol decreased and the good one increased, so she did not have to take pills.
I purchased Prosta Dan for the prostate twice a day and saw that the results of the values did not increase, thank God. I also started drinking the Pressure Tea for blood pressure and thank goodness I am now balanced. Notably, I take blood pressure pills, but I feel really good and balanced.
It was important to me to write this recommendation for everyone who needs it. I also didn't believe until I saw my wife's results, and then my own. It is very important to go to the physician for treatment and at the same time to add natural treatment with Nufar's products, which work and balance.
And for all of that, many thanks.
Hello Dear Nufar company,
For a long time now, I have been suffering from high cholesterol that gets worse over the years. The doctor recommended me to start medication treatment, but the medication I was taking had side effects of dizziness and after a few days I stopped taking it. I bought the “Cholesteren Tea” when I visited a nature shop without believing it would really help, but I thought it would not hurt either, and anyway I love drinking herbal tea.
To my surprise, with a routine blood test, I saw that, for the first time in over twenty years, my cholesterol level decreased. The attached document of my test results shows that the cholesterol decreased from 268 in March to 223 in June. This is after using the tea for about a month.
I hope that this blessed phenomenon continues. I also plan to try more of Nufar's products, hoping that the ability you have demonstrated will be valid with other products as well...
Attached please find the results of my lab test after drinking “Cholesteren Tea”.
