What substance is recommended for rinsing Physalia stings to prevent further nematocyst discharge?
Answer
Vinegar
Vinegar, which contains acetic acid, is strongly supported by current comparative research as the most effective initial step for treating stings from the Portuguese man-of-war (*Physalia physalis*). Its primary mechanism of action is preventative; it actively deactivates the unfired stinging capsules, known as nematocysts, that cling to the skin after contact. By deactivating these microscopic stingers, vinegar ensures they cannot release their venom payload when the victim moves or rubs the area. This neutralization must occur before any physical removal of tentacles is attempted, making it crucial for halting further envenomation, which is the immediate priority following exposure to the floating hazard.
