Quote from: Medusa: A novel from the NUMA files by Clive Cussler with Paul Kemprecos, G.P. Putnam’s Sons, Penguin Group (USA) Inc. (2009), pp 236-237.
“An antiviral has to kill the pathogens without hurting the host. The medusa toxin went beyond that, actually protecting its host organism’s health…for a while, anyway. The process is called hormesis. In small doses, a toxin can trigger repair mechanisms in the body, maybe even retard aging. It works in the same way exercise does, by stressing the body so that it changes the metabolism for the better.”
