Calcined Magnetite — Classic Formulas

Duan Ci Shi · Magnetitum Praeparata

Primary Actions

  • Anchors and calms the Spirit - used for restlessness, insomnia, palpitations, and agitation when a heavy settling mineral is needed.
  • Calms the Liver and subdues Yang - classically chosen for dizziness, headache, tinnitus, or blurred vision when Liver Yang rises upward.
  • Opens the ear orifices and brightens the eyes - one of the classic mineral medicines for tinnitus, hearing decline, and vision dimness associated with Kidney deficiency.
  • Aids the Kidneys in grasping Qi - extended to deficiency-type wheezing or breathlessness where the Kidneys fail to hold Qi downward.

Classic Formulas

  • Ci Zhu Wan (磁朱丸) - classic formula in which Ci Shi joins cinnabar to calm the Spirit, settle floating Yang, and benefit the eyes and ears.
  • Er Long Zuo Ci Wan (耳聋左慈丸) - tinnitus and hearing-loss formula lineage using Ci Shi to connect Kidney deficiency treatment with the ear orifices.
  • Ci Shi with Dai Zhe Shi or Shi Jue Ming - mineral combinations used when severe upward disturbance causes dizziness, tinnitus, and irritability.

Classical Text References

  • Me & Qi presents Ci Shi as a classic heavy mineral that anchors the Spirit, subdues Yang, opens the ears, brightens the eyes, and helps the Kidneys grasp Qi.
  • Classical sources cited by Me & Qi repeatedly connect magnetite with tinnitus, deafness, dim vision, and the broader Heart-Kidney or Liver-Kidney axis.
  • PREPARATION NOTE: Duan Ci Shi is not a new herb but the clinically prepared magnetite form, used because raw ore is too hard, impure, and difficult to reduce to a useful medicinal powder.
