Rating (out of 5): 2

Purslane (Portulaca oleracea) has a long history of use in traditional medicine systems, including Chinese and Middle Eastern medicine, for various inflammatory and gastrointestinal ailments, including ulcers. However, beyond its traditional use, there is emerging scientific evidence to suggest potential benefits for ulcer management, particularly gastric ulcers.

Several preclinical studies have explored the gastroprotective effects of purslane extracts in animal models. For example, research published in Phytotherapy Research (2010) demonstrated that purslane extract significantly reduced gastric ulceration in rats induced by ethanol and indomethacin. The mechanisms proposed include purslane's antioxidant activity, ability to reduce gastric acid secretion, and promotion of mucosal defense by enhancing mucus production and reducing inflammation.

Key bioactive compounds in purslane, such as omega-3 fatty acids, flavonoids, and polysaccharides, have been shown to possess anti-inflammatory and cytoprotective properties, which may contribute to healing and prevention of ulcer formation. However, most of the supporting data come from animal studies, and there is a lack of high-quality clinical trials in humans to confirm these effects.

In summary, while there is some scientific support, primarily from animal studies, indicating that purslane may help in the management or prevention of ulcers, human clinical evidence is limited. Thus, the scientific evidence is rated as 2 out of 5, indicating preliminary but not conclusive support for its use in this context.
