The tea is a loose herb the doctor brought back from China. He said I could buy it at any chinese herb store, but the quality might not be as good as the one he gave me.
I was given 3 little “quills” (a rolled tea leaf) I was told to break off 1/2 of one per day and use that tiny piece to brew 4-5 cups each day. The doctor called it bitter tea so I was expecting it to taste awful. It’s actually really delicious, it tastes like green tea, I would drink it all the time if I could.
Here’s a picture in case anyone wants to use it to track down some.
