Chinese medicine is a slow process thus I won't reco if junior is already coughing. coughing should not get worse. western med is more effective.
for my case I also brought to c eys but not improving after 3days so I brought to Kandang Kerbau Hospital a&e since cough has been close to a month n should have subside. Kandang Kerbau Hospital practice is to go xray for 3/4 weeks cough. found phlegm in ddi lungs n earlier prescription by gp the dosage is too low base on ddi's age & weight.
so my advice is dont't wait already bring junior to Kandang Kerbau Hospital a&e since xray is already incl in the fee, & as you dont want to turn into something serious & peace of mind as well as junior getting better prescription. Chinese med only when junior better & we want to tiao their body.
note as children attend cc thus recurrence of flu, cough will happen. best boost their immunity after they r well.
hope i've helped in some ways
