While these two formulas share the same ingredients, they differ in their application and therapeutic effects. This article aims to shed light on the distinctions between these two remedies, helping readers understand their unique properties and when to use them.

Xiang Sha Ping Wei Wan, also known as the Pill for Soothing Stomach and Harmonizing Qi, is primarily used to treat symptoms of stomachache, bloating, and poor appetite. This formula is designed to eliminate dampness, regulate the spleen, and harmonize the qi, thereby alleviating the aforementioned symptoms. The key ingredients in Xiang Sha Ping Wei Wan include:

2. Atractylodes (Cang Zhu): Atractylodes is used to strengthen the spleen and improve digestion.

3. White Peony (Bai Shao): This herb helps to alleviate pain and regulate the qi.

4. Ginger (Sheng Jiang): Ginger warms the middle burner and helps to dispel dampness.

On the other hand, Xiang Sha Yang Wei Wan, or the Pill for Nourishing Stomach and Harmonizing Qi, is formulated to treat symptoms of chronic gastritis, stomachache, and bloating. This formula focuses on nourishing the spleen, warming the middle burner, and harmonizing the qi. The key ingredients in Xiang Sha Yang Wei Wan are similar to those in Xiang Sha Ping Wei Wan, but with the addition of some different herbs:
