Wow !! I have never heard of this either. It sounds suspicious.
I have a licensed naturopath who is also a licensed acupuncturist and a doctor of oriental medicine. He has done alot of acupuncture on me, including when I had very active cancer in my body and he never told me I made him tired.
I suggest you try a different acupuncturist and see if you get the same reaction. You could bring the tea to the second acupuncturist or to a store where they sell Chinese herbs and see if they can tell what's in the tea.
Do you have a friend who can read Chinese? That person might be able to tell you more if the tea is in a package or box with Chinese language on it.
If there is a little English on the package try doing an internet search using those terms. Plum Flower Brand is a well known brand of Chinese medicine. That brand is easy to search on the internet.
Good luck. Take good care of yourself.
