Portulaca Oleracea Whole Herb Extract
Also known as: purslane, verdolaga, oilseed portulaca, Portulaca sativa, Portulaca molokiniensis, Portulaca oleracea
Overview
Portulaca oleracea is a succulent annual herb renowned for its impressive array of nutritional and medicinal benefits, making it a prominent functional food across various cultures. This herb is particularly distinguished by its high content of omega-3 fatty acids, flavonoids, alkaloids, and essential vitamins and minerals. Its therapeutic applications are often linked to antioxidant, anti-inflammatory, and hepatoprotective properties, leading to its historical use in addressing liver ailments, inflammatory conditions, and metabolic disorders. Recent studies, including randomized controlled trials and systematic reviews, have emerged, indicating its potential utility in non-alcoholic fatty liver disease (NAFLD) and other metabolic irregularities. The evidence supporting these benefits is moderate to high-quality, highlighting the herb's role in complementary and integrative medical practices.
Benefits
Research demonstrates that Portulaca oleracea offers multiple health benefits, especially for individuals with NAFLD. In a notable double-blind randomized controlled trial involving 70 patients, a daily intake of 700 mg over eight weeks resulted in significant improvements in liver steatosis and fibrosis. Participants also exhibited marked reductions in body weight, waist circumference, blood sugar levels, and discrepancies in lipid profiles, including lowered total cholesterol and triglycerides (p < 0.001). Additionally, potential antiviral and antifungal properties have been suggested, indicating broader therapeutic applications. Overall, individuals suffering from NAFLD may experience the most profound benefits from Portulaca oleracea supplementation.
How it works
Portulaca oleracea operates through various bioactive compounds that confer strong antioxidant and anti-inflammatory effects. These compounds bolster the body's antioxidant defenses and reduce oxidative stress within hepatic tissues, impacting inflammatory pathways by modulating markers such as interleukin-6 (IL-6) and high-sensitivity C-reactive protein (hs-CRP). Furthermore, constituents of the herb enhance the activity of antioxidant enzymes, including superoxide dismutase and glutathione peroxidase, thereby improving liver function and overall metabolic health. Nevertheless, further investigation into its pharmacokinetics is warranted for a comprehensive understanding.
Side effects
Portulaca oleracea is generally considered safe within recommended dosages, with only some mild side effects reported, such as paradoxical constipation, despite its known ability to alleviate this condition. Clinical studies indicate minimal adverse effects; however, long-term safety data remains limited. Notably, no rare side effects have been documented. Individuals on medications impacting liver function should take caution, and pregnant or breastfeeding women are advised to consult a healthcare professional prior to use to ensure safety.
Dosage
Effective dosages of Portulaca oleracea typically range from 700 mg to 1,400 mg daily, with 700 mg identified as the minimum effective dose based on clinical research. To optimize absorption, it is advisable to take the supplement with meals, particularly breakfast and dinner. Participants in clinical trials generally consumed two capsules daily. Currently, while no defined upper safety limit exists, doses as high as 1,400 mg have shown good tolerance in studies without any significant adverse effects.
