Fish Poison Makes Hot Feel Cold and Vice Versa
SoyChemist writes "Ciguatoxin causes bizarre neurological symptoms including temperature reversal, a burning sensation, and an imaginary feeling of loose teeth. It is produced by algae and accumulates in the fatty flesh of tropical fish. While traveling to the tropics, a man from England ate some bad seafood that contained the unusual poison. His story, and the tale of some unfortunate sailors of an earlier age who suffered the same affliction, appeared in the current issue of Practical Neurology and was summarized on the Wired Science Blog. Both the Wired blog and the peer-reviewed journal neglected to mention that the potent neurotoxin has been made from scratch by organic chemists."
Ethanol is commonly known to give feelings of warmth, ; in fact, the movie A Time For Drunken Horses is so named because the winter weather is so harsh that the only way the Iranian Kurds can get horses to work is to give them liquor.
