Researchers shed light on how to best treat a jellyfish sting

(CNN) - When it comes to home remedies, there's a lot out there. It's hard to say what's really effective and what's not.

Now, there's a new study that's shedding some light on what to do, and what not to do if you're ever stung by a jellyfish.

A paper published in the Annals of Emergency medicine says putting vinegar, alcohol, meat tenderizer or even urine on the sting may not be the way to go.

So what does work?

The study says your best bet is to put hot water or Lidocaine, which is a local anesthetic on the wound.

If you don't have any of that on hand, researchers say saltwater will also do the trick.
