I have this super irritating cough for almost 2 weeks. Been
coughing like mad every single day. Went to GP and Polyclinic, and
their cough medicine is useless
So i decided to try drink chinese herbal tea. The lady ask me,
cold or hot cough. Well the thing is i dunno i got phelgm anot as
so far i have not cough out any single phelgm (nor do i see any
yellow saliva), its just this uncomfortable feeling in the
throat
To play safe, i drink one dose for cold and one for hot.
Yestedat nite i nv cough so i though i recover and went to slp
in a air con room
Now coughing like mad again
Whenever you're not feeling well, ALWAYS REMEMBER TO DRINK
HOT/WARM. 
No COLD FOOD/DRINKS!
