Over three hundred years, dried roots of Dangshen have been used in enhancing vital energy, blood circulation, lowering the blood pressure, and for treatment of watery stool with poor appetite, neurosis, hematopoietic disease, poor gastrointestinal function, gastric ulcer and nephritis etc. We collected samples of Danshen from different sources and studied anatomy of roots.
