"worm excrement tea" used to be listed for sale on the CNNP Yunnan
Branch website (i think!) in the same section as loose leaf puerh.

It's a myth among pu'er drinkers that when the tea gets really old that
some insects can get inside of the tea and then die. Some people say
worms...some people say moths. In my experience, I've never seen it in

heh.
