New York Times:Vinegar Can Remedy Jellyfish Stings
Nothing can ruin a day at the beach like a jellyfish sting. And while such attacks are common, the methods for treating them vary, and many remedies can do more harm than good.
One exception is the application of vinegar, which according to several studies can deactivate the venomous nematocysts that jellyfish release. A study published in The Medical Journal of Australia showed that removing any tentacles left by a jellyfish, then dousing an injured body part with commercial vinegar or its crucial ingredient, acetic acid, could alleviate pain and “rapidly and completely” prevent the release of more venom.
Many of the methods that do not work are also some of the best known: rubbing alcohol, ammonia, meat tenderizer and even urine — which, contrary to conventional wisdom, is not usually very acidic. Even rinsing a sting with fresh water can be a bad idea, because the change in pH between saltwater and fresh water can prompt the release of more venom.
One important note: an attack by a Portuguese man-of-war, the jellyfish’s more dangerous relative, usually calls for serious medical attention. That is particularly the case when symptoms include muscle pain, shortness of breath, backache and hives.
THE BOTTOM LINE
Vinegar can be an effective treatment for jellyfish stings, but many other popular remedies can make the injury worse.
