Abstract

Objectives: Current clinical treatment regimes for inflammatory diseases have different drawbacks including side effects of the drugs and the high cost of long term treatment. In the last few decades different promising herbal medicines have been explored for their anti-inflammatory and anti-rheumatic effects, but conclusive evidences are not available in the case of crude Aloe vera gel for its anti-inflammatory effects. The objective of the study was to document the protective and curative roles of orally administered and peritoneally injected crude wild Aloe vera gel in carrageenan-induced inflammation in a rat model.

Methods: Inflammation was induced by injecting 1% carrageenan in the left hind paw of Wistar albino rat. Crude, unprocessed Aloe vera gel was peritoneally injected and orally fed to experimental and control rat groups to investigate its effect on paw joint edema by measuring the paw circumference with vernier caliper. MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] cell viability assay was performed to investigate the cytotoxic effect of the gel.

Results: Paw edema was brought to near normal levels in the experimental groups after the treatment with crude Aloe vera gel. Orally fed gel showed no cytotoxicity on macrophages and spleenocytes. Protective property of crude Aloe gel was also evident in both the experiments.

Conclusion: Aloe vera crude gel has both protective and curative properties against inflammation.
