In the author’s previous book ‘New paradigms for Shang Han Lun’, two clinical methodologies were introduced for the prescription of traditional Asian herbal medicine. One is Dr. Lee Jema’s individual constitutional perspective (Sasang Medicine), and the other is single herbal functional perspective of Dr. Todo Yoshimas (Yakucho). This book is mainly focused on the clinical application of Shang Han Lun providing the case studies of contemporary Korean medicine doctors and Kampo medicine doctors, in addition to the descriptions of Yakucho. It is more likely pathological approach of Shang Han Lun. However, it is also critical to consider the constitution of each individual to make more accurate diagnosis and prescription. please refer to ‘New paradigms for Shang Han Lun’ to further understand how to use the right formula for the right person from the constitutional medicine perspective. This book also provides 76 formulas with the related clauses excerpted from Kang Ping Shang Han Lun to help understand the formulas in the context of the original text. Kang Ping Shang Han Lun is the closest edition to the original, and my other book ‘New paradigms for Shang Han Lun’ also offers the full translation of the Kang Ping edition along with the historical background. Each formula is analyzed with modern interpretation of Shang Han Lun in the specific clinical settings. The author’s clinical case studies are also added. These clinical cases are the little fruits of her sixteen years of practice after struggling to find better way to approach to Asian Medicine. This book will provide herbal practitioners with stepping stones on the journey to mastering Asian Medicine.
