In antiquity, Egyptian Pharaohs took hibiscus tea to refresh and control body temperature. In Iran, the hibiscus flowers are used to calm the mind and improve sleep problems.

More recently, the hibiscus tea has been used to burn fat, reduce swelling, improve bowel function and control cholesterol.

As diuretic, hibiscus tea also serves to lower blood pressure and protect functions of the kidneys and liver.

properties

The hibiscus tea is low in calories (100 grams of dried flowers provide 37 calories, but you'll use an infinitely less to prepare a cup of drink), but it contains many essential nutrients for health.

Flavonoids - such as anthocyanins and quercetin - are responsible for much of the benefits of hibiscus tea, but the flowers are also sources of vitamins, minerals, carbohydrates and proteins.

Main hibiscus tea nutrients:

  • MineralsIron, magnesium, potassium, phosphorus, copper and calcium;
  • Vitamins: A, C, thiamine (B1), riboflavin (B2) and folic acid;
  • organic acids: Between 15 and 30% of hibiscus tea is composed of substances such as malic, tartaric and citric three types of phytonutrients that serve to strengthen the immune system and improve skin health.

Fibers and fats are also present in hibiscus flowers, but in very small quantity. Tea also contains no cholesterol and is not a source of caffeine.

Benefits of hibiscus tea

Here's how the hibiscus properties provide benefits to health and fitness. So, what is the hibiscus anyway?

1. Weight Loss

One of the main reasons why the hibiscus tea has gained the spotlight of the fitness world - including being endorsed by a number of famous - is its action on metabolism.

According to a survey published in the Journal of Ethnopharmacology, the hibiscus was responsible for a reduction in weight gain in obese mice. The slimming mechanism hibiscus is not yet fully known, but it is believed that tea helps you lose weight because:

  • Lowers blood glucose, hindering the accumulation of fat;
  • Hinders the synthesis of new fat cells;
  • Decreases of LDL cholesterol and triglycerides;
  • Inhibits pancreatic enzymes;
  • It has thermogenic effect (speeds up metabolism);
  • Blocks an enzyme involved in fatty acid synthesis.

Another study published in 2014 in the journal Food & Function hibiscus confirms these properties. In the human study, scientists found that hibiscus extract reduces obesity and inhibit fat accumulation.

In research conducted by Taiwanese scientists, it was shown that participants who consumed the extract for 12 weeks had a reduction in weight, body mass index, body fat percentage and waist circumference.

Another effect of hibiscus was to improve liver function in the presence of hepatic steatosis. For the authors, this hibiscus tea's effects can be attributed to polyphenols flower.

Finally, a research developed at Hokkaido University, Japan, has shown that hibiscus inhibits the alpha-amylase, an enzyme that converts starch into sugar. This means that the hibiscus tea after meals can help reduce the absorption of carbohydrates, effect which in turn contributes to weight loss.

2. Cholesterol Reduction

No less than 80 million Brazilians are with high cholesterol rates, and the bad news is that this number is constantly increasing. Poor diet, sedentary lifestyle, stress and hereditary factors have combined to leave more than a third of people with LDL cholesterol above the ideal range.

Of course the best way to lower cholesterol is to take care of diet and exercising, but some alternatives - such as the use of certain plants - can be of great assistance. One of these is exactly the hibiscus, which is proven to reduce the concentration of low density lipoproteins in the circulation.

Studies have shown that antioxidants and bioflavonoids present in H. sabdariffa flowers help improve LDL values ​​while reinstating HDL rates, the good cholesterol.

Taiwanese researchers published in 2007 Nutrition Research a clinical test in which it was noted that volunteers who received capsules with hibiscus extract showed a decrease from 8.3 to 14.4% cholesterol only one month of use of the compound.

Another scientific work, which included the participation of 222 patients showed that those with metabolic syndrome and received hibiscus extract had a significant reduction in total cholesterol and LDL - and at the same time, HDL rates - the good cholesterol - is increased circulation.

Volunteers who combined treatment of hibiscus with a diet also saw their triglyceride levels significantly to Defect, indicating the cardioprotective effect of hibiscus tea.

3. Helps in Diabetes Prevention and Metabolic Syndrome

Beside of hypertension and high levels of LDL, the excess sugar in the blood is one of a set of conditions that comprise Metabolic Syndrome. The term refers to metabolic risk factors that manifest themselves in a person and increase the chances of developing diabetes and heart complications.

In addition to pay attention to cholesterol and reduce deposits of abdominal fat, control glucose levels is another way to prevent metabolic syndrome, a condition that affects about 20% of the population.

In the same study (cited above) developed in Mexico with 222 participants, researchers found that hibiscus helps to control blood glucose and improves insulin resistance, two fundamental conditions for the prevention of diabetes.

4. Reduced Pressure

By stimulating renal function, hibiscus tea favors the elimination of excess fluids, reducing the volume of blood and lowering blood pressure. In a study published in Phytomedicine, it was found that volunteers who took hibiscus tea prepared with 10 grams of dehydrated cup of Roselle showed a reduction in blood pressure.

According to another study, this time in the Journal of Human Hypertension, regular consumption of hibiscus tea can help reduce systolic pressure up to 7.2 points.

Published in 2015 in the Indian Journal of Pharmacology, a Nigerian research has found similar results. By comparing the effects of hibiscus tea with lisinopril (a type of medicine used to treat high blood pressure) in hypertensive diabetics, researchers found that both reduced the blood pressure by more than 30% compared to placebo.

This means that the hibiscus is as effective as medication in treating hypertension - effect, the researchers said, it may be reassigned to the presence of anthocyanins in tea.

5. It is Diuretic

Based on the available scientific literature to date, researchers have observed that the diuretic effect of hibiscus tea is due to the action of H. sabdariffa as an aldosterone antagonist.

Produced in the cortex of the adrenal glands, aldosterone is a hormone which controls the retention of sodium and potassium elimination through the kidneys, thus contributing to the maintenance of water balance of our body.

For those who think of using hibiscus tea for weight loss, this means that in addition to stimulating fat burning, the drink also eliminates excess fluids, lowering the pointer balance and reducing bloating.

6. Improves intestinal function

The hibiscus tea is mildly laxative, as its active compounds improve digestion and promote intestinal transit. For best results with hibiscus tea, have a cup of the liquid upon waking, still fasting.

Phytonutrients hibiscus will "awaken" the renal and hepatic function, while the volume of water stimulates bowel movements, favoring the elimination of feces.

7. you can prevent cancer

Like other food rich in antioxidants, hibiscus contains phytonutrients that may slow the growth of cancer cells by reducing the amount of free radicals in the circulation.

A survey conducted by the Institute and Department of Biochemistry, Chung Shan Medical and Dental College, Taiwan, suggests that hibiscus protocatequínico acid acts as an antioxidant and antitumor inducing apoptosis (programmed cell death) of tumor cells.

8. Antioxidant

The hibiscus tea is not only to reduce the measures but also to maintain health. Antioxidants of hibiscus flowers have an important role in reducing the cell damage caused by oxidative stress.

Although free radicals are commonly associated with aging skin, this is not the only evil that can cause health: excess toxic substances also weakens the immune system and predisposes the body to disease - especially those involving the progressive loss of neurons (read Parkinson's, Alzheimer's).

We can therefore say that the hibiscus tea is used to fight free radicals, reduce inflammation and prevent neurodegenerative diseases.

9. protects the liver

Some studies have examined the effects of hibiscus tea on the liver and the preliminary results have been promising. In a survey published in Food and Chemical Toxicology, the leaves of hibiscus were responsible for a reduction in oxidative damage to the body, and antioxidants plant also reduced liver inflammation.

In addition to preventing future problems in the liver, these hibiscus tea estates also help treat liver disease already installed.
