   • 1766, Thomas Wallis (surgeon), The Farrier's and Horseman's Complete Dictionary: Containing the Art of Farriery in All Its Branches:

     For that kind of lax and scouring called bloody flux, see the article BLOODY FLUX.

     Flux, bloody flux and scouring feature from the first, but were overtaken in the 1650s by 'plague in the guts', soon renamed 'griping in the guts'. An apparent decline in bloody flux was more than matched by high levels of 'griping in the guts'.
