Should I keep giving a cat with ibd Miatake/dmg supplement?

We've been giving our cat a miatake/dmg supplement ever since she had a battle with cancer.  She got over the cancer but now is struggling with ibd.  My understanding of ibd is that the immune system attacks the cat's body so it seems as if we should stop enhancing her immune system with the maitake/dmg supplement.  But then, when reading sites regarding treatment of ibd, it says to give lysine (sp?) which supports the immune system so now I'm confused....

Any feedback would be greatly appreciated!

That is so great that she beat the cancer!     It seems like if its not one thing its something else. 

My Sebastian has chronic pancreatitis (confirmed) and suspected IBD (declined biopsy). I stay away from immuno-stimulants. DMG is definitely an immune booster.

IMO, true IBD in cats is an autoimmune disease, much like Crohn's in humans, and immuno-stimulants such as echinacea, for example, can make things worse. I have an autoimmune disease myself and a conference I went to had a whole lecture on this.

L-lysine works very specifically, typically for feline herpes virus (FHV). Feline herpes uses arginine, an amino acid, to replicate. L-lysine, another amino acid, counteracts the arginine so that less of it is being used to feed the FHV. I give l-lysine to Sebastian because he has FHV, but at a slightly reduced dose.

From http://www.allfelinehospital.com/site/view/206524_catcolds.pml:

 L-lysine.   This is an amino acid supplement.  The way it works is that for the herpes virus to replicate, it requires an amino acid called arginine in the replication process.  However, L-lysine can go into the same slot in the replication process that arginine can, but herpes virus cannot replicate with L-lysine in that slot.  In addition, herpes virus will take up L-lysine preferentially over arginine.  So, by flooding the body with L-lysine, we can stop the replication of the herpes virus, and allow the immune system time to suppress it.  L-lysine is a very safe supplement, and is available in a variety of formulations.  Dosing is generally 250mg-500mg once or twice daily.

I have a cat with probable IBD and I wouldn't give anything that boosts the immune system.  He is on a low dose of a steroid.  I know he is at a dose that is anti-inflammatory rather than suppressing his immune system but I think giving something that boost the immune system would counteract the steroid.
