The Myth About Vinegar And Jellyfish Stings

The common opinion:

Google Health says:

For other jellyfish stings, soak or rinse the area in vinegar (acetic acid) for 15-30 minutes to stop the nematocysts from releasing their toxins. If you do not have vinegar available, rinse in sea water,70% isopropyl alcohol, or Safe Sea Jellyfish After Sting® pain relief gel. Do not use fresh water.

The ‘vinegar myth’ is false. Instead, apply CPR to the victim, and get medical attention IMMEDIATELY.
eMedicine Health has an article about jellyfish sting symptoms:
