(Li Haoguo) Stops spermatorrhea, secures Qi, promotes the circulation of Qi stagnation, warms the Middle Jiao to promote appetite, and controls saliva secretion.
Meridian Tropism: Enters the Spleen meridian; also enters the Heart and Kidney meridians. It is a substance that promotes Yang and dispels Yin. (Also serves as a supplement to address insufficiency of Heart Qi, Mingmen, and Sanjiao.)
Preceding Theory: Zhang Congzheng (Haicang) stated: Zhizi Ren is originally a Spleen herb. It primarily regulates the Ministerial Fire and Sovereign Fire. In Jixiang Wan, it enters the Lung meridian; in Sizijunzi Tang (Four Gentlemen Decoction), it enters the Spleen meridian.
Contraindications: Miao Xiyong (Jingshu) stated: For syndromes belonging to dryness-heat, or patients with internal fire, it should not be used. Therefore, vomiting caused by heat rather than cold, or qi rebellion caused by anger with uneven breath, are contraindications.
