I drink 1/4 cup of George's Roadrunner Aloe Vera as a preventative measure. Aloe is healing to the gut lining, but you need to make sure you're consuming a brand with the aloin component removed as it can cause cramping and D.
I would disagree with the saleslady in that you won't necessarily be a "happy camper" in 24 hours. Natural supplements don't usually work wonders in a short amount of time. They can support healing over time, though.
Diagnosed with ulcerative colitis spring 1999.
Maintenance dose sulfasalazine.
Probiotics, l-glutamine and fish oil caps. George's aloe vera juice. Oregano oil antibiotic, antiviral, antifungal. Long-term remission with only minor blips.
