Evidence Level

Emerging

Aloe vera inner gel has emerging clinical evidence for ulcerative colitis based on the Langmead et al. (2004) RCT showing meaningful improvement in disease activity. The anti-inflammatory mechanism (COX-2/NF-kB inhibition) provides biological plausibility. GERD evidence is limited to one pilot study. A critical distinction is between inner leaf gel (therapeutic, anti-inflammatory) and whole leaf/latex (stimulant laxative, potentially harmful). Only IASC-certified, decolorized inner leaf products should be used for gut health applications.
