mr.me,
sorry dear without your consent, i asked your question at thrity nine homeopathic, allopathic, herbal forums / mailing lists for getting knowlege and clarification. All of them replied that
coryza and catarrh represent different conditions. These words have not same meanings. These words have different meanings and applications in medical science. These words used to represent different conditions/stages. Every body was so annoyed on me on asking this simple questions. They said why are you asking this simple question. I replied I am confused with reply of RICKY who is a good homeopath and practicing in UK. May be these words have same meaning in homeopathy?

but in repertory different symptoms are mentioned for
coryza and catarrh
