Just for a comparison, in the past, whenever I catched a flu like this, it took at least a week to have running nose and congestion controlled even under Tylenol. After that, coughing started and lasted for about 1 month. Not at this time. Thanks for the right Guang Ci Tang herbal remedies, I did not have cough and I am completely fine within a week. I am so happy and strongly recommend these remedies to everyone.
