Qi Deficiency of the Lung

The Lungs, the vital organs that govern respiration and bring fresh air and qi into the body, are the first line of defense against external pathogens. They also play a key role in regulating the voice and preserving the body's fluids. When the Lung Qi, or vital energy, becomes depleted, the body's ability to perform these functions becomes impaired, leading to a variety of signs and symptoms.

Signs & Symptoms

  • Weak cough
  • Spontaneous daytime sweating
  • Frequent sickness
  • Shortness of breath
  • Dislike of speaking
  • Tiredness
  • Weak voice


One of the primary symptoms of Lung Qi Deficiency is a weak cough, as the weak and depleted nature of the condition causes the qi to rebel and move upwards, resulting in coughing. Shortness of breath, a hallmark aspect of qi deficiency symptoms that tend to be worse with exertion, is also caused by the poor descending of qi and weak respiration.

The Lungs' relationship with the exterior of the body also becomes impaired when the Lung Qi is weak. The Lungs influence the Defensive Qi, or Wei Qi, of the body, spreading it along the surface to warm the body and protect it against external pathogens. When the Lung Qi is weak, the defensive qi also becomes weak, leading to an increased susceptibility to colds and sensitivity to cold weather, as well as spontaneous daytime sweating due to the inability to regulate the opening and closing of pores.


There are several factors that can contribute to the development of Lung Qi Deficiency, including:

  • Weak digestive system
  • Prolonged sadness or grief
  • Excessive use of the voice
  • Exposure to pollutants or toxins

Lung Qi Deficiency is also more common in people with a constitutional tendency towards qi deficiency or those who have undergone prolonged periods of illness or physical exhaustion.


Treatment for Lung Qi Deficiency involves nourishing the qi and strengthening the respiratory system through the use of herbs, acupuncture, and lifestyle changes, such as getting enough rest, eating a nourishing diet, and avoiding exposure to pollutants and toxins. In severe cases, treatment may also involve the use of Western medicine to support respiratory function. By addressing the root cause and supporting the body's natural healing processes, the Lungs can regain their vitality and the body can function at its best.
