With those antibiotics, they are worried more about MRSA than zoa juice. You wouldn't use that with a typical zoanthid juice (Palytoxin) injection. You would use a steroid and antihistamine. Palytoxin effects the sodium potassium pump in your cells that believe it or not can lead to paralysis, respiratory depression and even death. It's crazy, but true.
Thanks for reporting the story. Sorry it had to happen to you. Hopefully we can all learn from it. Sheesh. I always tell my students that learning hurts lol.
