How does cough medicine stop a dry, tickly or wet cough?
In: 1
I had a class in college where this was discussed. The professor said it’s literally just sticky syrup coating the back of your throat. This offers a short lived feeling of relief and gives you something to cough up instead of just continually irritating your throat with dry hacking. You can get a similar effect from candy, although for me the menthol seems to help a little. Also, let’s not knock the benefits of placebos. Sometimes ignorance is bliss.
