Introduction
In general, Erchen Pills may be effective for stomach distension and gas caused by phlegm-dampness obstruction and qi stagnation of the spleen and stomach. However, they are not suitable for all cases of stomach bloating and gas. Proper symptom-targeted use is necessary when taking them. For daily prevention and relief of stomach distension and gas, it is important to maintain regular eating habits, avoid overeating, consume fewer raw, cold, greasy, and gas-producing foods, maintain a healthy emotional state, and engage in appropriate physical activity to promote gastrointestinal motility.

Generally, Erchen Pills have a certain effect on stomach distension caused by phlegm-dampness obstruction and spleen-stomach Qi stagnation. However, they are not suitable for all cases of stomach bloating, and appropriate symptom-targeted usage is necessary. Detailed analysis is as follows:

Erchen Pills are a type of patent Chinese medicine primarily composed of ingredients such as dried tangerine peel, Pinellia (Banxia), Poria (Fuling), and licorice. They have functions of drying dampness, resolving phlegm, regulating Qi, and harmonizing the stomach. For stomach distension caused by phlegm-dampness blockage or spleen-stomach Qi stagnation—such as when accompanied by symptoms like nausea, vomiting, chest and epigastric fullness, and excessive phlegm—Erchen Pills can help alleviate discomfort by regulating spleen and stomach functions, resolving phlegm-dampness, and promoting the movement of Qi.

However, if stomach bloating is caused by other factors such as food accumulation, insufficient gastric motility, gastric ulcers, etc., the effect of Erchen Pills may not be significant, and may even fail to relieve symptoms due to inappropriate application. Moreover, Pinellia in Erchen Pills is warm and drying in nature; long-term or excessive use may irritate the stomach and intestines, so appropriate dosage must be followed.

In daily life, to prevent and relieve stomach distension, it is important to maintain regular eating habits, avoid overeating, reduce consumption of raw, cold, greasy, and gas-producing foods, maintain a positive emotional state, and engage in appropriate physical activity to promote gastrointestinal motility and maintain normal spleen and stomach function.

How long does it take for Erchen Pills to take effect?
Erchen Wan may show effects within 3 to 7 days. If the phlegm-dampness symptoms are severe, such as chronic cough with excessive phlegm, significant chest tightness and abdominal distension, and the patient has a weak constitution with poor spleen and stomach function, the body's recovery process may be relatively slow, and it may take 5 to 7 days to feel symptom improvement. In this case, the medication should be taken continuously at the prescribed dosage, while maintaining a light diet to avoid increasing the burden on the spleen and stomach.

Is Mecobalamin Tablets harmful to the stomach?
If the gastric function is normal, taking Mecobalamin tablets at the conventional dosage generally does not cause significant irritation after entering the gastrointestinal tract. The stomach can normally digest and absorb the medication without causing discomfort such as stomach pain or nausea. However, if the patient has gastric diseases such as gastric ulcer or gastritis, or takes a large dose on an empty stomach, it may cause mild irritation to the gastric mucosa, leading to symptoms such as gastric distension or mild stomach pain.
