I took great care in formulating this cough syrup for you. This is for the cough that comes with or after a serious illness. The cough that just will.not.quit. This cough often falls in the category of post-infection complications. Say you've had the flu, and just as you think you're getting better, you get sicker. That sickness often includes a miserable, phlegmy, death wish of a cough. And this is the syrup that will renew your will to live.
