I am a mother of a 3 year old. My son is suffering from cold and cough. He gets vomiting whenever he coughs continuously. Also, he gets cold and coughs very often in the last one year. Until 15 months of age, he did not get even a single episode of cold or a cough. I am so worried about him now. His cough is very severe at night, and he did not sleep yesterday due to a constant cough. He never gets a runny nose, and I am very much concerned about this. This time, he had fever and cold initially, and his cough started after four days. Also, he lost weight due to a cough. He maintained good weight till 1.5 years of age and nowadays, it is very hard for him to gain weight.
He had the same type of a cough before six months, and it was diagnosed as viral fever and cough. For a cough, I gave Ascoril-D for two days. Then started with tulsi, betel leaves, cumin and honey kashaya once in the morning and once at night. Kindly tell me some remedy for his cough. Also, how to increase his immunity as well as weight?
