Centipede venom fights pain

Molecule from toxin makes mice less sensitive to acid, heat

A chemical found in centipede venom wipes out pain just as well as morphine does, a study in mice shows.

When researchers injected mice with a molecule isolated from the venom of the Chinese red-headed centipede, mice showed fewer signs of pain in response to heat, acid and nasty injections, Chinese and Australian scientists report September 30 in the Proceedings of the National Academy of Sciences. In some tests, the compound, called Ssm6a, erased pain as well as, or better than, morphine.
