Comment(s)
No studies were found comparing the two treatments. Most studies have been done in Australia on Box Jellyfish stings, for which, vinegar is used to prevent stinging cells adherent to the skin from discharging.
Clinical Bottom Line
Vinegar has been shown to work in Australian jellyfish, but there is no data on bicarbonate use.
