If need be, take these characters to a Chinese herb shop or supermarket and you’ll be guided to the ingredients (black beans, dry lotus leaves - 1 big piece per tea, etc.)
Please note, my Tai Chi sifu gave this recipe to me. He’s a renowned Chinese herbal doctor, and has treated my family since before I was born. HOWEVER, I am not a doctor, and therefore I recommend consulting your own healthcare professional before taking this tea. I am simply sharing this information as something that was helpful to me and my family.
