Apricot Kernel (Ku Xing Ren) and Perilla Leaf (Zi Su Ye) are less commonly seen in cough syrups, but have incredibly powerful efficacy when paired together. Ku Xing Ren is said to direct Qi downward to calm coughing and wheezing, whereas Zi Su Ye disperses pathogenic Cold and enhances the Lungs. What that means is that this is a perfect remedy for Cold Cough, which may present itself in wheezing, weakness, chills, cold, flu, or even asthma. Take one teaspoon, three times daily, with a small amount of boiled water. Always consume breakfast before taking first dosage of the day.
