How are nodules formed according to traditional Chinese medicine?

Generally, according to traditional Chinese medicine (TCM) theory, the formation of nodules may be related to improper diet, emotional injury, qi stagnation with blood stasis, liver qi stagnation, kidney deficiency with cold congealing, and other factors. Patients are advised to receive symptom-based treatment under medical guidance to avoid interfering with disease recovery. Specific analyses are as follows:

1. Improper Diet

Excessive consumption of spicy, stimulating, greasy, or rich foods can lead to accumulation of damp-heat in the body, impairing the spleen and stomach and subsequently disrupting the normal circulation of qi and blood. Prolonged accumulation of damp-heat pathogens may result in nodule formation. Such nodules are often accompanied by symptoms such as indigestion and abdominal distension. For nodules caused by dietary factors, it is recommended to follow medical advice and use spleen-strengthening and dampness-resolving medications such as Liu Jun Zi Tang, Ling Gui Zhu Gan Tang, or Shen Ling Bai Zhu San. Patients should also adjust their diet by reducing intake of oily foods and increasing physical activity.

2. Emotional Injury

Long-term mental stress, anxiety, depression, and other negative emotions can cause stagnation of qi, impairing organ function and leading to poor circulation of qi and blood, thereby forming localized nodules. The development of such nodules is often associated with emotional fluctuations and general bodily discomfort. In such cases, patients are advised to regulate their emotions promptly; when necessary, professional psychological counseling or therapy may be sought to alleviate nodule-related symptoms.

3. Qi Stagnation and Blood Stasis

Emotional suppression, high stress levels, and irregular lifestyles may all lead to impaired qi flow, resulting in blood stasis and obstructed circulation of qi and blood in certain areas, ultimately forming nodules. These are commonly accompanied by symptoms such as chest tightness, abdominal bloating, and low mood. Under medical guidance, patients may use blood-activating and stasis-resolving medications such as Danshen Dripping Pills, Tao Hong Si Wu Tang, or Shao Fu Zhu Yu Tang, along with traditional therapies like acupuncture and cupping to promote smoother flow of qi and blood.

4. Liver Qi Stagnation

As qi flow becomes obstructed, the circulation of qi and blood is affected, leading to pathological changes such as nodule formation. The liver governs the smooth flow of qi and prefers free-flowing conditions while being adversely affected by depression. Impaired liver function or prolonged emotional depression can both lead to liver qi stagnation. In such cases, it is recommended to use liver-soothing and stagnation-relieving medications such as Chai Hu Shu Gan San, Xiao Yao Wan, or Shu Gan Jie Yu Capsules under medical supervision, combined with psychological support to maintain emotional well-being.

5. Kidney Deficiency with Cold Congealing

Insufficient kidney yang fails to warm the body, leading to local cold congealing and impaired circulation of qi and blood, which may result in nodule formation. This condition may be accompanied by symptoms such as aversion to cold, cold limbs, soreness and weakness in the lower back and knees, and increased nocturnal urination. Treatment may include prescriptions such as Jin Kui Shen Qi Wan, You Gui Wan, or Liu Wei Di Huang Wan, as directed by a physician. Additionally, patients are advised to keep warm, avoid cold exposure, and consider appropriate heat-based therapies.

Throughout the treatment process, patients are encouraged to maintain healthy lifestyle habits, avoiding late nights and excessive fatigue. Attention should also be paid to dietary regulation, avoiding excessive consumption of raw, cold, or greasy foods.
