Runs, You must not have gone to their website. There is a disclaimer that ECR will not work if it's a twisted intestine.

But if it's a solid impaction or twisted intestine, this would only prolong the diagnosis by a vet?

I just googled it (ECR or Equine Colic Relief) and it states that it is a formula administered like a wormer (looks like the bottle comes with a syringe to squirt in horse's mouth). It is $85 a bottle which they say includes shipping. Or $80 bottle if order two and $75 per bottle if order 3 bottles. One bottle per colic bout for one average adult horse. Seems expensive but just the exam by a vet is that price (and not including anything a vet would do for the horse having a colic episode). So it appears it could be worth it. Shelf life of 12 years. Seems to be a long shelf life with natural ingredients. HDG

I have never heard of it. What exactly is it?

Has anyone heard of ECR "Equine Colic Relief" ?? Good or bad?? I saw it used recently and was impressed with the results, so I bought some. Thanks! Vicky
