Home treatment for jellyfish stings

The tentacles of jellyfish contain venomous cells. If you come into contact with those cells, they pierce your skin and release poison, even if the tentacle is severed from the jellyfish.


  • Pain and burning, up to several hours
  • Raised welts that might last for many days
  • Skin rashes may appear days or weeks after the sting.


  • Rinse immediately in salt water (not fresh water).
  • Keep movement to a minimum to reduce release of venom.
  • Use a knife or tweezers to remove tentacles.
  • Vinegar may stop the stinging.
  • After the above treatment, immersion in hot water may also provide some pain relief.
  • Apply lavender, tea tree or roman chamomile essential oil to the sting.


  • Jellyfish are more common when the water is warm.
  • If you have trouble breathing, consider it a medical emergency.
  • If you develop hives (allergic reaction), get to an emergency room. Other allergic reactions for which you should seek medical help if they are not short-lived:
  • It is not advised to urinate on the sting or to use meat tenderizer or lemon juice (old home remedies).
