Subject: Where to find slippery elm bark
             I've always had luck finding it in health food stores, but I 
                  suppose a GNC might carry it as well.
                   
                  I've never been of the mind to give animals or people any kind 
                  of treatment "just because" -- there has to be a reason. I 
                  would not recommend giving your ferret slippery elm bark just 
                  to give it. Also, I would not recommend using it with ferrets 
                  who have tummy troubles without seeing a vet -- oftentimes 
                  ulcers can be fixed up with medicine and a little TLC, and the 
                  slippery elm just treats the symptoms.
                   
                  Good luck!
                  Amy, Dave, Sarah & Paul (and their gaggle of giggling ferrets)
