'Bad egg' gas controls blood flow

Without a little hydrogen sulphide to relax the muscles, blood pressure starts to rise.

As the smell of rotten eggs wafts past your nostrils, you're more likely to be revulsed than relaxed. Yet researchers have now shown that the 'bad egg' gas, hydrogen sulphide, is produced in certain animal cells and acts as a muscle relaxant to regulate blood pressure.

  • Now I think I know why the Chinese have the traditional wisdom of eating thousand year old eggs to lower their "Fire" - probably the hydrogen sulphide in those preserved eggs helps in lowering blood pressure.

  • This is a very exciting and great discovery. Better understanding of how NO and hydrogen sulphide work to regulate blood pressure has a life-saving benefit for those with heart disease. If the research team probe more and invent more effective anti-hypertension drugs by collecting the knowlege of this discovery, the team should be credited with Nobel prize for Medicine. The discovery of NO gas was awarded with Nobel prize too.
