Herbal remedies for cough
I have a 10 year old mare that has a consistent, exercise induced cough. No fever, no discharge, no obstructions. She has been seen by 2 different vets, both coming to the conclusion that she's most likely has an allergy to mold/pollen. There is no sign of infection. She very rarely coughs with the exception of work. She can go for 5-10 minutes working with no cough and then will at times have a strong coughing fit about 15 minutes into working. It generally passes after about 5 minutes or so. Sometimes will reoccur after a walk break and going back to work. I have tried Cough Free and it seemed to help some, but not completely. I'm hosing her bedding down as well as her hay to decrease her exposure to dust. She does get about 10 hours of turnout per day. What other herbs are helpful for such a case? She was on spirulina in the past and it didn't seem to help much. I don't want to put her on strong medications if it's not needed, which at this point I don't think it's bad enough to warrant that, but I would like to give her some kind of support.
