Ci Wu Jia Root Classic Formulas … Natural Herb Library

Primary Actions

Tonifies qi and strengthens the Spleen ... Ci Wu Jia is used for fatigue, poor appetite, and worn-down resilience without the heavier cloying feel of richer tonics.
Tonifies the Kidney and strengthens sinews and bones ... it fits chronic low-back soreness, weak limbs, and recovery after long-standing debility or overexertion.
Calms the spirit while supporting adaptive resilience ... traditional use extends to insomnia, dream-disturbed sleep, and mental fatigue when depletion and overwork coexist.

Ci Wu Jia tea, tincture, and tonic-wine traditions ... functional-support use more characteristic than a single famous textbook formula.
Qi and Kidney support pairings with Huang Qi, Dang Shen, or Gou Qi Zi ... used when fatigue and depletion dominate.
Wind-damp weakness pairings with Du Zhong and Niu Xi ... traditional strategy when soreness and weakness coexist.

Traditional summaries describe Ci Wu Jia as invigorating qi, strengthening the Spleen, and nourishing the Kidney while also calming the mind.
Its use sits between tonic and functional-support categories rather than at the attacking or purgative end of the materia medica.
