Has been a lifesaver of 4 of my horses to date - It is the 1st product I reach for if I 1 of my horses is down. Even if we are at a show it helps with stress colic as well and they can still compete! Thank-You for having this product, will never be without it. This product is my go to each and every time I have a horse down. Has always worked and reverses the symptoms of a colic. Some quicker than others depending on how long they might have been down for so 15 minutes if caught early to 2hrs or so if caught after 6 hrs. I know it will work through Banamine and this is why the 1st horse took longer - vet was out twice and nothing he did medically worked for this mare. The GutFlush is what saved her life!
