Under normal circumstances, the main functions and effects of Yanhu Weian Capsules include soothing the liver and harmonizing the stomach, promoting qi circulation to relieve pain, strengthening the spleen to aid digestion, regulating qi to relieve abdominal distension, and alleviating gastric discomfort. Detailed explanations are as follows:
1. Soothe the Liver and Harmonize the Stomach
Yanhu Weian Capsules contain ingredients such as Corydalis (Yanhusuo) and Nutgrass Flatsedge Rhizome (Xiangfu). Corydalis helps promote qi circulation and activate blood flow, while Nutgrass Flatsedge Rhizome regulates liver qi. Together, these ingredients harmonize liver and stomach function, improve symptoms caused by disharmony between the liver and stomach, such as epigastric distension and pain, belching, and acid regurgitation, and help restore balance to the liver and stomach's qi mechanisms.
2. Promote Qi Circulation and Relieve Pain
Ingredients such as Corydalis and Costus Root (Muxiang) in the formula promote qi circulation through the meridians and have effects of activating blood circulation and relieving pain. For symptoms of gastric pain, distension pain, or dull pain caused by qi stagnation, this formula can unblock the stomach's qi mechanism, dissipate stasis, reduce pain and discomfort, and relieve spasm-like gastric pain.
3. Strengthen the Spleen and Aid Digestion
Ingredients such as Atractylodes (Baizhu) and Poria (Fuling) in the formula strengthen the spleen and invigorate qi, enhancing the digestive functions of the spleen and stomach. For symptoms such as poor appetite, indigestion, and postprandial abdominal distension caused by spleen and stomach weakness, this formula promotes digestion and absorption of food, reduces food stagnation in the stomach, and improves digestive function.
4. Regulate Qi and Relieve Abdominal Distension
Ingredients such as Nutgrass Flatsedge Rhizome and Costus Root regulate qi, relieve depression, and alleviate abdominal distension. For symptoms such as epigastric fullness and discomfort, or chest and hypochondriac distension, this formula can unblock qi circulation, relieve the sensation of fullness in the stomach, maintain smooth gastrointestinal function, and reduce abdominal discomfort.
5. Alleviate Gastric Discomfort
Through the combined effects of soothing the liver, regulating qi, and strengthening the spleen, Yanhu Weian Capsules can regulate various gastric discomfort symptoms. It can provide auxiliary relief for symptoms such as stomach pain, acid regurgitation, belching, and indigestion caused by conditions like gastritis and peptic ulcers, thereby improving the overall condition of gastric discomfort.
