Introduction
Under normal circumstances, the main effects and functions of Shen Ling Bai Zhu Wan include invigorating the spleen and replenishing qi, drying dampness and stopping diarrhea, nourishing the lungs and boosting qi, regulating the gastrointestinal tract, and improving physical weakness and fatigue. During the period of taking Shen Ling Bai Zhu Wan, the diet should be light and bland; consumption of raw, cold, greasy, or spicy foods should be avoided to prevent interference with the drug's effectiveness or additional burden on the gastrointestinal system. Individuals with colds or fever should not take this medication.

Generally, the main effects and functions of Shen Ling Bai Zhu Wan include invigorating the spleen and replenishing qi, drying dampness and stopping diarrhea, nourishing the lungs and enhancing qi, regulating the gastrointestinal tract, and improving physical weakness and fatigue. The specific analysis is as follows:

1. Invigorating the Spleen and Replenishing Qi

Shen Ling Bai Zhu Wan contains ingredients such as ginseng, white atractylodes, and poria. Ginseng strongly replenishes vital energy, white atractylodes invigorates the spleen and dries dampness, while poria strengthens the spleen and eliminates dampness. These ingredients work synergistically to enhance the functions of the spleen and stomach, improve symptoms caused by spleen qi deficiency such as poor appetite, abdominal distension, reduced food intake with loose stools, and help restore normal physiological functions of the spleen and stomach.

2. Drying Dampness and Stopping Diarrhea

Ingredients such as white atractylodes and coix seed in the formula have functions of drying and eliminating dampness, effectively removing excess dampness from the body. For symptoms such as unformed stools, chronic diarrhea, and sticky, uncomfortable bowel movements caused by excessive dampness due to spleen deficiency, this formula can dry and drain dampness while strengthening the spleen and harmonizing the stomach, thereby reducing dampness accumulation in the intestines and alleviating diarrhea symptoms.

3. Nourishing the Lungs and Enhancing Qi

In traditional Chinese medicine, it is believed that "the spleen is the mother of the lung," and weakness of the spleen and stomach easily leads to insufficient lung qi. By invigorating the spleen and replenishing qi, Shen Ling Bai Zhu Wan can indirectly nourish lung qi, improve symptoms of lung qi deficiency such as shortness of breath, coughing, clear and thin phlegm, and weak voice, making it especially suitable for individuals suffering from both spleen and lung qi deficiency.

4. Regulating the Gastrointestinal Tract

Multiple ingredients in the formula can promote gastrointestinal motility and enhance digestive and absorptive functions. For symptoms caused by gastrointestinal dysfunction, such as indigestion, abdominal distension, and belching, this formula can regulate the qi movement of the spleen and stomach, promote food digestion and nutrient absorption, and maintain stable gastrointestinal function.

5. Improving Physical Weakness and Fatigue

Ingredients such as ginseng and Chinese yam can replenish vital energy and enhance physical vitality. For symptoms such as body fatigue, limb weakness, and low spirits caused by spleen-stomach qi deficiency and insufficient blood and qi production, this formula can promote the generation of qi and blood through replenishing qi and invigorating the spleen, alleviate the state of physical weakness, and enhance body energy.

During the use of Shen Ling Bai Zhu Wan, a light diet is recommended, avoiding raw, cold, greasy, and spicy foods, which may affect the drug's effectiveness or increase the burden on the gastrointestinal tract. This medicine should not be taken during colds or fevers to avoid prolonging the illness. If symptoms do not improve after taking the medication for some time, medical advice should be sought promptly to adjust the treatment plan.
