I use George's Roadrunner aloe vera juice. It has the irritating, laxative component (aloin) removed. It's tasteless... like drinking water. I have a quarter cup in the morning on an empty stomach and in the evening before bed for maintenance.
Diagnosed with ulcerative colitis spring 1999. Have been in remission for years with only a few minor blips.
Maintenance dose sulfasalazine. Probiotics, vitamin D, fiber supplement and fish oil caps. George's aloe vera juice and l-glutamine for gut healing. Mostly grain-free and dairy-free low carb diet.
