Lung Clearing and Anti-inflammatory Pill is a proprietary Chinese medicine which is mainly composed of Chinese medicine’s Ma Xing Shi Gan Tang plus Drabanemerosa hebecarpa and Artificial Niuhuang. It mainly treats phlegm-heat and lung-heat cough, such as coughing up yellow phlegm, chest pain, fever, constipation and yellow urine. If it is taken for a long time or the patient belongs to the cold-damp and yang-energy insufficient physique, including the elderly, pediatrics, pregnant women with poor physique, it is easy to have the symptoms of inability to eat, loose stools, or even aggravation of the original condition after taking the Lung-clearing and Anti-inflammatory Pill. This is because Chinese medicine believes that any product that clears heat, resolves phlegm, or is bitter and cold is likely to injure the yang qi of the spleen and stomach, which is the foundation of the later life, and will lead to damage to the lung qi after being injured. As the drugs for treating phlegm-heat and lung-heat cough are too bitter and cold, taking the drugs for a long time will lead to the loss of yang qi and the appearance of physical discomfort, including headache, chills, cold sweats, loose stools, long and clear urine, and especially a significant decrease in appetite, which is its side effect. It is important to pay attention to the dosage time of this kind of proprietary Chinese medicine, and decide how long to take it according to the patient’s specific condition and whether the transformation of cold and heat occurs.
