What formula would you choose for treating Qi stagnation in the stomach?

The choice of Ding Xiang Shi Di Tang for treating Qi stagnation in the stomach is appropriate because this formula specifically addresses conditions related to stagnation and cold, particularly in the context of digestive function. Ding Xiang, or clove, is known for its warming properties and can help to alleviate cold-type conditions that lead to Qi stagnation in the stomach. Shi Di, or persimmon calyx, helps to alleviate nausea and vomiting, which can often accompany symptoms of Qi stagnation in this area.

Ding Xiang Shi Di Tang enhances digestion, promotes the free flow of Qi, and addresses cold-induced stagnation that might cause discomfort or fullness in the stomach. This aligns with the principles of traditional Chinese medicine, which emphasize the importance of both Qi and warmth in promoting healthy digestion and alleviating symptoms associated with stagnation.

In contrast, the other formulas do not specifically target Qi stagnation in the stomach as effectively. Shen Ling Bai Zhu San focuses primarily on the strengthening of the Spleen Qi and the transformation of dampness, making it less suited for classic presentations of Qi stagnation specifically. Xiao Jian Zhong Tang is more geared toward addressing Yang deficiency and abdominal pain rather than stagnation alone. Si Jun Zi Tang is a classic formula
