Summary Background Anecdotally, aloe vera is used to treat gastric ulceration, although no studies have yet investigated its efficacy in horses. Objectives To test the hypothesis that aloe vera would be noninferior to omeprazole in the treatment of equine gastric ulcer syndrome. Study design Randomised, blinded clinical trial. Methods Forty horses with grade ≥2 lesions of the squamous and/or glandular mucosa were randomly assigned to one of two groups. Horses received either aloe vera inner leaf gel (17.6 mg/kg bwt) b.i.d. or omeprazole (4 mg/kg bwt) s.i.d. for approximately 28 days, after which a repeat gastroscopic examination was performed to determine disease resolution. Horses with persistent lesions were offered a further 28 days of treatment with omeprazole (4 mg/kg bwt s.i.d.) and were re‐examined on completion of treatment. Results Efficacy analyses were based on 39 horses that completed the trial. Equine squamous gastric disease ( ESGD ) was observed in 38 horses; improvement and healing rates in these horses were 56% and 17%, respectively, in the aloe vera group, and 85% and 75%, respectively, in the omeprazole group. Healing was less likely to occur in horses with prolonged gastric emptying. Equine glandular gastric disease ( EGGD ) was less common than ESGD (n = 14) and numbers were too small to perform meaningful statistical analyses. The hypothesis that aloe vera would be noninferior to omeprazole was not supported. Main limitations No placebo control group was included. Limited numbers preclude any comment on the efficacy of aloe vera in the treatment of EGGD . Conclusions Treatment with aloe vera was inferior to treatment with omeprazole.
