This was an add I saw on the forum page.
Seeing as equine influenza is caused by a virus I don't see how an antifungal and antibiotic can work
I also don't get how it improves lung capacity - I didn't know that was possible (apart from exercise and conditioning). Besides, how do you measure lung capacity on a horse? (now Flash, take a deep breath and breath out as fast as you can into this balloon...) And if you can measure a horse's lung capacity, how do they know it even works?
It sounds a bit fishy to me... what do you think?
