Cats Claw for UC

Has anyone here used the supplement "Cats Claw" for IBD or specifically for their Ulcerative Colitis? If so how is it working for you. I've read that it's good for intestinal disorders. But it's also an immune system stimulant and since UC is treated by immune suppressing type drugs, because of the immune system attacking pathogens in the body, was wondering if it would help or worsen the symptoms of UC. Any thoughts on this?

it is up for debate if the UC is attacking pathogens or attacking the body's own cells. But, it is more of an overactive immune system issue - I would be to start with small amount, and to only do it in combination with anti-inflammatory treatment.
