Slippery Elm Bark Powder

Just wondering if anyone has an opinion on using slippery elm bark powder in the treatment of ulcers or digestive issues. i have used it on and off over the years, and ive got a horse that is susspected of ulcers. ive heard mixing it with aloe is a good mix.
Any comments please

Thoroughly recommend its use. Aloe Vera is also good, so combined there shouldn't be any issue. Slippery Elm can also be beneficial on tendon sprains.
