There is no such thing as the “fastest” way to replenish lung qi today. You have to choose the right treatment for yourself, and you can replenish your lung qi through diet and medication. 1. Diet: Some of the foods in our daily life have medicinal effects, such as yam, lily, lotus root, fungus, pig lungs, etc., which can help replenish lung qi to a certain extent. 2. Drugs: Herbs or formulae can be chosen to replenish lung qi. Herbs such as Astragalus, Codonopsis, Chinese yam, Cordyceps, etc. have the effect of replenishing lung qi. Formulas such as Lung Tonifying Soup and Lung Tonifying Soup can be used to treat coughing and wheezing (coughing and wheezing caused by weakness of the lungs) and shortness of breath and spontaneous sweating. For patients with lung qi deficiency, medication should be administered after pulse diagnosis by a physician, paying attention to keeping warm, avoiding cold, exercising appropriately to improve the body’s immunity, and eating less spicy, irritating, cold and greasy food.
