Introduction
Heliotropium indicum, a member of the Boraginaceae family, has local applications in Nigeria for treating various ailments, particularly ulcers and fevers. This study aimed to investigate the histo-gastroprotective effects of the aqueous extract derived from Heliotropium indicum leaves on gastric mucosa ulceration induced by Indomethacin in Wistar rats. Indomethacin, known to cause gastric ulcers by inhibiting prostaglandin synthesis, disrupts the balance between aggressive and defensive factors in the gastrointestinal tract, leading to ulcer formation. Previous studies suggested that Heliotropium indicum could possess gastroprotective properties; thus, this research sought to provide scientific validation for its traditional use as a treatment for gastric ulcers.
Histopathological Findings of Heliotropium Indicum
The histological analysis revealed that Heliotropium indicum exhibits dose-dependent histo-gastroprotective effects. In rats treated with only Indomethacin, significant mucosal damage was observed, including erosion of mucus-secreting cells and other gastric structures. In contrast, the gastric mucosa in rats pre-treated with various doses of the plant extract, as well as Ranitidine (a standard control), displayed normal morphological characteristics. This protective effect is likely attributed to the phytochemical components found in Heliotropium indicum, particularly alkaloids, tannins, and saponins, which may facilitate mucosal protection by potentially enhancing endogenous prostaglandin production and providing an astringent action that forms a protective barrier over ulcer sites.
Conclusion
The findings from this study support the traditional use of Heliotropium indicum in managing gastric ulcers, demonstrating its ability to protect gastric mucosa against Indomethacin-induced damage. The successful preservation of the gastric mucosa integrity in the presence of the extract points to its therapeutic potential, reinforcing the need for further research to isolate and identify the active compounds responsible for these effects. Future studies could enhance the understanding of the mechanisms behind the gastroprotective properties of Heliotropium indicum, potentially paving the way for more effective treatments for gastric ulcers rooted in both traditional and contemporary medicine.
