Benefits of Aloe Vera

Evidence-Based Benefits

• Ulcerative colitis — Langmead et al. (2004, n=44, RCT) found aloe vera gel 100ml twice daily produced clinical remission in 30% and improvement in 37% of UC patients vs 7% and 7% placebo
• Anti-inflammatory activity — acemannan and other aloe polysaccharides inhibit COX-2 and NF-kB, reducing mucosal inflammation (Langmead et al., 2004)
• Mucosal healing — aloe vera gel promotes epithelial cell proliferation and migration, supporting wound healing in GI mucosa (Jettanacheawchankit et al., 2009)
• GERD symptom relief — a 2015 pilot study (Panahi et al., n=79) found aloe vera syrup (10ml/day) was comparable to omeprazole and ranitidine for GERD symptom reduction

What the Research Says

Aloe Vera is a natural remedy supported by clinical evidence for various therapeutic applications. In the management of ulcerative colitis, Langmead et al. (2004) conducted a randomized, double-blind, placebo-controlled trial demonstrating that oral administration of aloe vera inner gel significantly improved disease activity and provided meaningful relief to patients.

For burns, two systematic reviews highlight aloe vera's efficacy. Huang et al. (2024) found that topical application reduced wound-healing time by 3.76 days compared to other treatments, while Sharma et al. (2022) reported a reduction of 4.44 days in healing time for second-degree burns.

Aloe vera also shows promise in oral health. A systematic review by Zou et al. (2022) revealed significant improvements in symptoms of oral ulcers, while Cássia-Santos et al. (2025) found that aloe vera gel effectively reduced the severity of oral mucositis compared to placebo.

It is crucial to distinguish between different forms of aloe vera products. Inner leaf gel, which contains anti-inflammatory properties through COX-2/NF-kB inhibition, is recommended for therapeutic use. In contrast, whole leaf or latex may act as stimulant laxatives and could pose risks if not properly processed. Only IASC-certified, decolorized inner leaf products are advised for gut health applications to ensure safety and efficacy.
