Hi Sir,
I suffered from Flu( cold, cough and fever) And after medication, i am feeling better but taking some medicines and syrup for dry cough currently. I am feeling very weak now.
I am 60 years old. I have very low immunity. I often get cold and fever. Could you please refer a safe tonic or
vitamin for long term use. So that I can get rid of body weakness and improve taste and hunger also to improve immunity .
Thank you
