Introduction
Under normal circumstances, Yanhu Weian Capsules, as a commonly used traditional Chinese medicine preparation, have functions and effects including harmonizing the stomach and relieving pain, soothing the liver and regulating qi, alleviating abdominal distension and pain, improving nausea and vomiting, and regulating gastrointestinal function. When using Yanhu Weian Capsules, it is important to clearly identify the applicable syndrome patterns; patients with deficiency-cold of the spleen and stomach or excessive internal heat due to yin deficiency should use them cautiously.
Generally, as a commonly used traditional Chinese medicine, Yanhu Weian Capsules have functions and effects mainly including harmonizing the stomach and relieving pain, soothing the liver and regulating qi, alleviating epigastric and abdominal distension and pain, improving nausea and vomiting, and regulating gastrointestinal function. Detailed analysis is as follows:
1. Harmonize the stomach and relieve pain: Yanhu Weian Capsules contain ingredients such as Corydalis Rhizome (Yanhusuo), which are effective in regulating stomach qi and relieving pain. They are suitable for symptoms such as stomach pain, dull pain, or distension pain caused by disharmony of stomach qi. By relaxing the gastric qi movement, they reduce gastric spasms and alleviate pain and discomfort.
2. Soothe the liver and regulate qi: This medication can regulate liver qi and is suitable for gastric discomfort caused by disharmony between the liver and stomach, manifested as worsening stomach pain during emotional irritability or symptoms such as distension and oppression in the hypochondriac region. By balancing the qi movement of the liver and stomach, it reduces the impact of liver qi stagnation on the stomach.
3. Alleviate epigastric and abdominal distension and pain: For symptoms such as epigastric and abdominal fullness and pain caused by stagnation of qi in the gastrointestinal tract, Yanhu Weian Capsules can promote smooth qi movement in the gastrointestinal tract, reduce gas accumulation, alleviate abdominal distension and pain, and improve abdominal discomfort.
4. Improve nausea and vomiting: For symptoms such as nausea, dry heaving, or vomiting caused by upward rushing of stomach qi, this medication can regulate the direction of stomach qi movement, inhibit upward rushing of stomach qi, reduce nausea, decrease vomiting episodes, and help restore normal gastrointestinal function.
5. Regulate gastrointestinal function: For individuals suffering from long-term gastrointestinal dysfunction caused by disharmony between the liver and stomach or dysregulation of stomach qi, taking Yanhu Weian Capsules can comprehensively regulate gastrointestinal function, balance the qi movement of the liver and stomach, improve gastrointestinal digestion and absorption, and reduce recurrent stomach discomfort.
When using Yanhu Weian Capsules, it is important to clearly identify the applicable syndrome patterns; patients with deficiency-cold of the spleen and stomach or excessive fire due to yin deficiency should use them cautiously. Additionally, medication should be taken under medical guidance to control dosage and duration, avoiding prolonged self-administration to ensure medication safety and effectiveness.
