It wouldn't be medicinal unless it had bones in it. You know when
Shang dynasty oracle bones started turning up in fields in Henan, the
farmers who found them thought they were dragon bones, so they ground
them up and drank them as tea.

I'd actually really like to see a recipe for Guangdong liangcha if you
can get one. I shy away from drinking stuff like that off the street
because of the sanitation aspect. I'd also be interested to hear more
about the idea that water from different sources has different qi
qualities. What waters are considered good for brewing tea, and how
can you tell what a water's qi is like?
