Roasted Aconite Lateral Root … Classic Formulas

Pao Fu Zi · Aconiti Lateralis Radix Praeparata

Primary Actions

  • Restores collapsed Yang and revives devastated fire ... Pao Fu Zi is a strongly warming prepared aconite lane used when cold collapse presents with icy limbs, faint pulse, somnolence, or severe Yang exhaustion.
  • Warms Heart, Spleen, and Kidney Yang ... it is used for deep deficiency-cold patterns with diarrhea, edema, abdominal cold pain, weak circulation, and failure of water transformation.
  • Warms the channels and disperses severe cold pain ... the roasted whole-root-forward form is associated with stubborn cold-damp painful obstruction, weak low back, and fixed pain that improves with heat.
  • Supports the pulse and lower-burner fire ... it is chosen when profound Yang weakness affects palpitations, chronic fatigue, or collapse-level cold.

Classic Formulas

  • Si Ni Tang ... archetypal rescue formula for Shaoyin collapse, cold extremities, and a nearly extinguished pulse.
  • Zhen Wu Tang ... warms Spleen and Kidney Yang while mobilizing retained fluids for edema, dizziness, and abdominal pain.
  • Fu Zi Li Zhong Tang ... strongly warms the middle burner for chronic diarrhea, weak digestion, and deep interior cold.
  • You Gui Wan ... restores Mingmen fire for chronic lower-body cold, weakness, and Kidney-Yang deficiency.

Classical Text References

  • Classical Fu Zi traditions in Shang Han Lun and Jin Gui Yao Lue treat the prepared lateral root as indispensable for restoring Yang, warming fire, and dispersing severe cold, while always respecting its toxicity.
  • Paozhi literature differentiates whole-root and slice forms because roasting, steaming, and slicing affect handling, decoction, and the balance between rescue, warming, and pain-relieving uses.
  • Modern dispensing inference ... most current sources discuss prepared Fu Zi broadly rather than isolating Pao Fu Zi as a separate pharmacology category, so this page follows the whole-root roasted lane within that broader prepared-aconite family.
