According to the US researchers, the gas that comes out with many stink bombs may also play a role to control blood pressure.
The foul odor of flatulence is the result of those small amounts of hydrogen sulphide that are generated by bacteria live in the human gut.
However, it appears that the gas can also be produced by an enzyme that is found in blood vessels.
The tests in mice may help to find some new treatments for high blood pressure, the Science journal says.
Researchers from John Hopkins University, Maryland, discovered that the gas was generated in the cells along with blood vessels by an enzyme named CSE.
The researchers engineered the mice to be deficient in this enzyme and they found that levels of hydrogen sulphide were quite reduces in a comparison with normal mice.
