Strange "health" things

Germany has some health-related things that are new to me!

You can find Sauerkraut juice at the supermarket...evidently it can be used for "cleansing" or a hangover cure.

or while hiking along the other day we ran into a "Kneip". I thought it was a kiddy pool, and I was told that is was not. It's a pool with cold water (I think this one is fed from a stream) where you march around, holding onto the railing in the middle. It is supposed to be good for circulation, which Germans are very concerned about.
