Rating (out of 5): 2

Purslane (Portulaca oleracea) has a long history of use in traditional medicine systems, including Traditional Chinese Medicine and folk practices in Europe and the Middle East. It has been used as a remedy for bleeding disorders, wounds, and inflammation, which may relate to its perceived effects on capillaries and blood vessels. Historical texts sometimes attribute purslane’s benefits to its astringent and anti-inflammatory properties, which could theoretically support capillary health by reducing capillary fragility or bleeding tendencies.

From a scientific perspective, purslane is known to be rich in omega-3 fatty acids, flavonoids, and antioxidants such as vitamin C and vitamin E. These compounds are generally considered beneficial for vascular health. Some in vitro and animal studies have demonstrated that purslane extracts can reduce oxidative stress and inflammation, which could potentially protect blood vessels, including capillaries. However, direct scientific evidence specifically linking purslane to improved capillary function or reduced capillary fragility in humans is lacking. Clinical trials targeting capillary health endpoints are not available as of 2024. Thus, while the traditional use exists and there are plausible mechanisms, strong scientific validation for this specific application is limited.
