I found partial answers in earlier posts (early as 2007) and pass them along for the many who read my first and second posts. In my second post I asked if Chunyi advised drinking more than one glass of yin-yang water daily, and what are the benefits. You can do an Internet search for exact posts.

1. One earlier post stated that Chunyi advises drinking one glass of yin-yang water daily.
2. There is almost nothing on benefits, except the balancing benefits (of balancing yin and yang). 3. Shawn Grim (2007) made an interesting statement that in some specific situations Chunyi recommends drinking yin yang water hot; but usually allow it to cool to "warm" before drinking.

An article on the benefits of yin-yang water would be most interesting. And helpful.
