The extremely hot peppers, known as chiles, are present in many cultures and are responsible for giving the strong flavor, sometimes to the limit of pain, much of the world's hottest sauces, from Mexico to India.

The good news for fans is intense flavors that the peppers would be a good remedy for hypertension. Scientists already knew of its beneficial effect in the short term, following an acute ingestion. But now it has been found, by experiment with rats, which are also effective to relax blood vessels and control blood over time.

Although further research is needed to confirm this effect in humans, scientists now have some clues: hypertension in northeast China affects more than 20% of the population, while in the Southwest Asia where the diet is rich in hot peppers, the figure is between 10% and 14%.

"People in these regions like to eat hot and spicy with lots of chili peppers," says Zhu. "For example, a popular dish in my hometown, Chongqing, is the spicy pot". Apart from confirming these variables still missing chile determine the amount necessary to elicit a beneficial effect in humans.
