Two Excellent Zhi Zi (栀子Gardenia Fructus) Formulas for Sleep
Continuing the discussion of classical formulas for sleep, Sharon introduces two effective zhīzǐ formulas: Zhīzǐ Chǐ Tāng and Zhīzǐ Gānjiāng Tāng.
She begins with zhīzǐ itself, the fruit of the gardenia plant: bitter in flavor and cold in nature, it discharges fire, dispels vexation, clears heat through urination, cools blood, and resolves toxins. Its key action is to disinhibit the shàoyáng pivot. When that pivot is inhibited, descending heat (the physiological life-force) accumulates and turns pathological, affecting all three jiāo. Zhīzǐ is uniquely able to clear heat across all three. It works especially well when an inhibited pivot agitates the spirit or blood and concentrates the urine to a hot yellow.
Both formulas treat an agitated spirit manifesting as insomnia, differing by where the blocked pivot sits. Sharon uses Zhīzǐ Gānjiāng Tāng when the insomnia involves too much thinking (waking and unable to turn the mind off), and Zhīzǐ Chǐ Tāng when the patient wakes with a distinct feeling of anguish. When patients relate to neither, a zhīzǐ formula isn't appropriate.
A follow-up post will explore why dàndòuchǐ and gānjiāng are used.

One of my students, Polina Shneyderman, recently posted her results using Zhīzǐ Chǐ Tāng as follows:
