What are the symptoms of constipation due to qi deficiency?

Symptoms of constipation due to qi deficiency include dry and hard stools, black-colored stool, headache, dizziness, pale complexion, general weakness, low energy, and poor appetite. When difficulty in defecation occurs, treatment primarily focuses on reinforcing qi and moistening the intestines, such as using modified Huangqi Tang (Astragalus Decoction). Patients can also improve their condition through dietary therapies aimed at eliminating dampness. For example, they may consume Chinese yam or taro, and red beans are also effective for removing dampness.
