Gallia nectar
Gallia nectar was a Talaxian beverage made from a flower that bloomed once every six years and grew only near a certain lake in Paxau. It was the specialty of the Paxau Resort. 

In 2373, Neelix, Harry Kim, and Tom Paris each had a glass of Gallia nectar before Paris changed the program to be more "fun". ()
