Classical Text References

  • SPECIES DISAMBIGUATION: The pinyin 'Feng Xian Tou Gu Cao' (凤仙透骨草) indicates the Impatiens-derived variant of Tou Gu Cao — 'Feng Xian' (凤仙) is Impatiens balsamina L. (garden balsam/touch-me-not; Balsaminaceae), used as a regional source of Tou Gu Cao in northern and eastern China; the XLSX source assigns the official Latin Herba Speranskiae Tuberculatae (which strictly refers to Speranskia tuberculata) to both this herb (#84) and the primary Tou Gu Cao drug (#85) — the two plants share the TCM indication for Wind-Damp Bi syndrome but differ in botanical source; Impatiens balsamina is also the source of Ji Xing Zi (急性子, seeds) and Feng Xian Hua (凤仙花, flowers), two separate TCM drugs
