I was told by a Chinese medicine woman, as she called herself, that I had too much internal heat. Often I feel cold so I didn't understand. She told me that internal heat is totally different from the feeling of being cold or hot. I was drawn to this tea and tried it without knowing about the internal heat issue. But I did know I have trouble with liver and kidney according to non-traditional treatment. I found out internal heat is associated with liver issues. I feel so much better when I drink even one cup a day. I forgot the name of the tea and brand and finally found it here. I can't wait to receive my 10 boxes! It tastes pleasant and mild. This is the only store where I could find it online.
