Spirit Pearls is based on the Shanghan lun formulas Suanzaoren Tang and Baihe Huashi San as well as the clinical case histories of the Northern Chinese master physician Dr. Wu Sheng’an, whose approach to difficult and recalcitrant diseases reflects the lineages of the imperial court physician Zhu Mulin and the middle and upper burner teachings of the 18th century clinician Huang Kunzai. This unique herb combination calms shen and neutralizes anxiety/trauma by stabilizing the yin of the Heart and Lung, opening the orifice of the Heart, and reversing energetic counterflow affecting the chest and head region.
