I’m living in Canada for last 15 years and I’ve this problem of constant throat infection and cough. I have been suffering from this for the past several years years. I consulted many doctors, but nothing helpeds me. I have been using all sorts of medication, nasal sprays etc, still I suffer the same. I searched online for this and found similar cases a lot. In one site ( Horton spices Markham ) I found a list of herbs that can be used to soothe the pain and irritation. Will these herbs work for throat infection and cough? Has anyone tried these?
