The degree of pain reduction in test subjects using a specific jellyfish (cnidaria) sting inhibitor and repellent lotion, compared to control subjects being protected by a normal water repellent sunscreen or no sun lotion at all. The jellyfish exposed skin parts will be treated for pain relief with hot or cold therapy or a commercially available local pain relief product (xylocain) from pharmacy.

| Measure | Time frame |
|---|---|
| Main Objective: The purpose of the study is to investigate the effectiveness of a sun lotion containing a specific Jellyfish sting inhibitor versus regular sun lotions as controls. ;Secondary Objective: Investigate the effectiveness of hot/cold immersion for the treatment of Jellyfish (Cyanea sp) stings versus local pain relief with prescription free pharmaceutical drugs.;Primary end point(s): The primary outcome is a clinically important reduction in pain as measured by the visual analogue scale (VAS). Secondary outcomes is to count the number of nematocyst fired when use of protection versus no protection. | — |
