Persistent dry cough

A 3 year old girl came in with persistent dry cough for few months not responded to her allopathy meds.
Due to shortage of meds with GP in Malaysia her Dr started her on honey only. She was admitted a few times before due to same problem.
I have treated her previously for her asthma and covid. Her numbers of admission to hospitals is getting less now.
For her current problem I gave her low dose anti viral combo, epstein barr, thuja and morgan pure.
She vomited twice after the meds. And within 2 days her cough is getting much better.
