Loquat (Pi Pa) and Fritillary Bulb (Chuan Bei) are the two most commonly used herbs for treating a severe cough, especially a productive one, due to their ability to cool inflammation, strengthen the lungs, dissolve phlegm. This herbal blend is best used for a Hot Cough which can appear as belabored breathing, productive cough with yellow or brown phlegm, physical weakness, fever, and sweating, but may help relieve symptoms of Cold Cough as well. Mix two teaspoons of Herbal Loquat Extract with tea or water for a delightful taste. Take as needed.
