Works very well for my olderv20 year old gelding with EPM.

I purchased this for my 21 yo mare. She has had a cough for at least 10yrs. Vets say allergies. She has had a cortisone shot which did help for a few months but the cough came back. I have tried so many things for her and nothing really helps. The Jiaogulan seems to help . She seems to cough a little less with some reduction of the discharge from her nostril. I also have her on the spirulina. She has been on that for 2+ months. I think these do help.
