    What does it do?

    Asthma is a common chronic lung disease that inflames and narrows the airways, causing symptoms like coughing, wheezing, chest tightness, and shortness of breath. Asthma can be caused by many factors such as air pollutants, weather change, viral respiratory infections (e. g., the common cold). Asthma is not curable, but the symptoms can be well controlled with inhaled bronchodilators like albuterol at the acute asthma attack and with glucocorticoids for long term prevention

    Asthma has been long recognized in traditional Chinese medicine (TCM) and can be distinguished into the cold-type or hot-type, depending on the general condition of the body heat. In the cold-type asthma, the body feels chilly, shows aversion to cold, likes hot drink, has abundant whitish sputum. In contrast, if the phlegm is hot and thick, the body is thirsty and likes cold drink, the asthma is considered hot-type. In TCM, the occurrence of asthma is related to the weak kidney function

    Su Zi Jiang Qi Tang was developed several centuries ago to deal with the cold-type asthma. The Chinese medicine applies to cough with wheezing, shortness of breath, fullness and distress in the chest, abundant whitish sputum, slippery or whitish tongue coating. Additionally, the Chinese medicine is especially helpful for ones who have lower back weakness and cold legs, which are signs of kidney Yang weakness often seen in older people

    Modern applications of Su Zi Jiang Qi Tang include asthma (bronchial asthma), chronic bronchitis, and pulmonary emphysema. In a study that included 49 chronic bronchitis patients at their acute phase, Su Zi Jiang Qi Tang was prescribed for treatment in the form of decoction for 10 to 15 days. The patients were at the age of 41 to 75, had the disease for 6 to 35 years, and were diagnosed according to the standard of the modern internal medicine. In the term of TCM they also showed the deficiency of the Lung and the Kidneys. After the treatment, 30 patients (61%) showed significant improvements, 15 (30%) showed some improvements, and 4 (9%) had no imrovement.1

    Su Zi Jiang Qi Wan may come in slightly different formulations. Su Zi Jiang Qi Wan/Pian of Guang Ci Tang is completed with 11 Chinese herbs. Noticeably, both Rou Gui (Cinnamon bark), for warming the kidney Yang function, and Chen Xiang (Aquilaria), for enhancing the asthma relieving effect of the formula, are present in the Chinese medicine

    Zi Su Zi (Perilla seed) is the chief Chinese herb in the formula that redirects rebellious Lung Qi downward to stop wheezing and dissolves phlegm to stop coughing

    Hou Po (Magnolia bark) moves Qi downward to arrest wheezing, transforms phlegm, and resolves chest distention

    • Qian Hu (Peucedani root) ventilates the Lung, clears phlegm, and stops coughing

    Zhi Ban Xia (Prepared Pinellia rhizome) is a main Chinese herb that transforms phlegm and stops vomiting

    • Chen Pi (Tangerine peel) expels dampness and transforms phlegm. The Chinese herb acts together with prepared pinellia rhizome for cough and asthma due to excessive phlegm in the Lung

    Dang Gui (Angelica sinensis root) is a common blood tonic herb. Its moistening property also neutralizes the drying properties of Perilla seed and other herbs in the formula

    Rou Gui (Cinnamon bark) tonifies the Kidneys and enhances the Yang energy of the Yin-Yang principle

    • Chen Xiang (Aquilaria wood) is a precious Chinese herb that descends rebellious Qi and regulates the Middle. It also tonifies the Kidneys and holds Qi

    • Sheng Jiang (Ginger) ventilates the Lung and disperses Cold

    Gan Cao (Licorice root) harmonizes the digestive function and synchronizes the action of multiple herbs. The Chinese herb also moistens the Lung, relieves cough and transforms phlegm

    Da Zao (Chinese date) moderates and harmonizes the action of other herbs
