Biotic Neural Itching
So after a google search, this is apparently the dialogue of the eterni-gel ad on Illium (still had trouble finding a youtube video of it):
Asari #1: Hey, are you okay? You seem touchy. It’s not… biotic neural itching, is it?
Asari #2: I’ve tried everything!
Asari #1: Don’t let anyone know, but I had the same thing. Eterni-gel cleared it right up!
Announcer: Eterni-gel. Because nothing should stop you from embracing eternity! [x]
I feel like the potential for headcanoning is endless on this one. It seems obvious that if it prevents an asari from embracing eternity (*wink wink nudge nudge*), then it’s a sexual disease/disorder of some kind. Because asari #1 says “don’t let anyone know”, it’s likely something embarrassing to have.
We know it has something to do with the nervous system (because it affects melding and because its symptoms manifest as “neural itching”. Yet it’s completely curable, and with a gel no less! I think someone who knows science should think up something sciency for this one…
