Water of Life

Uisce beatha is the traditional Irish word for whiskey. It means water of life.

Akvavit is a traditional Nordic distilled spirit. It means water of life.

In Dune, the water of life is...

liquid exhalation of a sandworm ... produced at the moment of its death from drowning which is changed within the body of a Reverend Mother to become the narcotic used in the sietch tau orgy. An "awareness spectrum" narcotic.

I picked up a bottle of two of the three. If only I could find some liquid exhalation of a sandworm for a true side-by-side comparison. That would make for one hell of a weekend!
