cold symptoms
"First time user. Was having a slight deep cough, which alone would've been fine but it was accompanied with shortness of breath, wheezing and tightness in my chest (common asthma symptoms). I haven't had this problem in years so I asked a pharmacist. She recommended this and one dose made a huge difference.  The tightness went away and the breathing got so much better. Even the slight cough was productive now.  Definitely recommend this to anyone with the same symptoms."
