I think just the simgle swoon would be better, but make it longer... say a couple of minutes.
Partial wounds could be simulated through tunnel vision, loss of hearing, slight fever and dryness of the throat. The victim becomes dizzy and begins to experience an itchy rash, then the poison goes to work on the central nervous system causing severe muscle spasms, followed by the inevitable drooling. At this point, the entire digestive system collapses, accompanied by uncontrollable flatulence, until finally, the poor bastard is reduced to a quivering, wasted piece of jelly.
