This is the last thing I want to hear, lucky for me, none of my friends ever read my blog… so they won’t have an excuse for stinking up the car on road trips.

Today I learned that hydrogen sulphide —the smelly rotten-egg gas in farts controls blood pressure in mice.

The unpleasant aroma of the gas, called hydrogen sulfide (H2S), can be a little too familiar, as it is expelled by bacteria living in the human colon and eventually makes its way, well, out. It also produced by an enzyme in blood vessels where it relaxes them and lowers blood pressure.

Those with higher levels of the gas had lower blood pressure than rodents with less.

Researcher Dr Solomon Snyder said: “Now we know hydrogen sulphide’s role in regulating blood pressure, it may be possible to design drug therapies that enhance its formation as an alternative to the current methods of treatment for hypertension.”

However, “the gas could also have negative effects on other parts of the body.” – Like the nose!

This study just furthers my justification for getting everybody on my Christmas list a 6 pack of these fart deodorizer pads.
