My son is suffering from cough ( not dry) especially during night time and during early hours is there any home remedy?

my son age is 4 years 6 months i am already using the medicine prescribed by the doctor.

Give a half cup pomegranate juice with a pinch of ginger powder and a pinch of Pippali powder.

OR



Give half a cup of fresh grape juice, mixed with some honey before drinking. It act as an expectorant which allows to get rid of sticky phlegm.
