None of those old wives' tales "cures" work.
Here's a real cure:
You got to go all by yourself, to the middle of the woods, where you know there's a spunk-water stump, and just as it's midnight you back up against the stump and jam your hand in and say:
'Barley-corn, barley-corn, injun-meal shorts,
Spunk-water, spunk-water, swaller these wars,'
and then walk away quick, eleven steps, with your eyes shut, and then turn around three times and walk home without speaking to anybody. Because if you speak the charm's busted."
This is off-topic, but cool: Comet Encke's tail ripped off by coronal mass ejection.
The most common cure in use today seems to be "Ignore the war and hope it goes away. If we pretend it isn't real it can't get any worse".
---Rushing towards history...
Actually, a proven way to get rid of wars is to cut the war until it bleeds, then the body politic realizes that the war is an infection and attacks it.
It's weird how it almost makes sense...
