Hydrogen sulfide joins the list of the body's friendly, if foul, gases
Hydrogen sulfide deserves its bad reputation. It's famous for filling the air of high school chemistry labs with the smell of rotten eggs. One strong whiff of the noxious gas can knock you to the ground. Too much can kill you.
Aside from its odorous infamy, hydrogen sulfide, or H2S, has long been considered biologically unimportant. But it turns out that H2S produced in the body manages many major biological functions. Some preclinical data show that H2S can ameliorate the side effects of anti-inflammatory drugs. And just last December, scientists reported that relatively high doses of H2S extend the life span of the minute roundworm Caenorhabditis elegans. Perhaps, such research suggests, the Fountain of Youth is a chamber of tha
