Acupuncture has become more popular in recent years because it can help many patients who have not found relief through conventional medicine. As people have become more aware of acupuncture, they have lots of questions about how and why it works. This book attempts to answer the most frequent questions our own patients have asked during their visits. A better understanding of acupuncture can help patients cooperate with their acupuncturist for faster improvement of their illness. And because acupuncture is only a branch of traditional Chinese medicine (TCM), we also introduce other aspects of Chinese medicine in this book, including herbal therapy, cupping, bleeding, folk therapy, and more. The information of this book is based on the author's own understanding about Chinese medicine and goes far beyond the scope of the standard Chinese medicine textbooks. Therefore, professional acupuncturists will also find it useful to expand their own knowledge about Chinese medicine.
