The effects of purslane (Portulaca oleracea) on glycemic indices: A GRADE-assessed systematic review and meta-analysis of randomized controlled trials. Phytother Res 2023; 37:5529-5540. [PMID: 37661794 DOI: 10.1002/ptr.7997] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 08/12/2023] [Accepted: 08/16/2023] [Indexed: 09/05/2023]
Abstract
Although several studies have revealed the benefits of purslane on glycemic indices, the results of some studies reject such effect. Therefore, aim of this meta-analysis of randomized controlled trials (RCTs) was to assess the effects of purslane supplementation on glycemic indices. Scientific international databases as Scopus, Web of Sciences, PubMed, Embase, and the Cochrane library were searched up to December 2022. For net changes in glycemic indices, weighted mean differences (WMDs) were calculated using random-effects models. Purslane supplementation had a statistically significant reduction in fasting blood glucose [FBG, WMD: -6.37; 95% CI: -9.34, -3.40, p < 0.001]. In addition, purslane did not significant effect on serum levels of insulin [WMD: -0.74; 95% CI: -2.58, 1.10; p = 0.430], homeostasis model assessment for insulin resistance [HOMA-IR, WMD: -0.25; 95% CI: -0.88, 0.37, p = 0.429], and QUICKI [WMD: -0.01; 95% CI: -0.01, 0.03, p = 0.317] compared with the control group. The results of our meta-analysis revealed a beneficial effect of purslane supplementation as a tool to decrease FBG levels, but not to HOMA-IR, insulin, and QUICKI levels. However, future high-quality, long-term clinical trials are needed to confirm our results.

IRANIAN JOURNAL OF BASIC MEDICAL SCIENCES 2022; 25:1275-1285. [PMID: 36474567 PMCID: PMC9699952 DOI: 10.22038/ijbms.2022.63264.13967] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Accepted: 08/02/2022] [Indexed: 01/25/2023]
Abstract
Metabolic syndrome (MetS) is defined as a disorder with multiple abnormalities, including obesity, high blood pressure, dyslipidemia, and high blood glucose. MetS is the best-known risk factor for type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD), and obesity. With the globally increasing prevalence of MetS and its related abnormalities, attention to safe and effective prevention and treatment of this complex disorder has been increased. In particular, most treatments have been devoted to using natural agents that could provide more reliable and effective medicinal products with fewer side effects. Portulaca oleracea L. (purslane) is an herb whose therapeutic properties could be found in some ancient medical books. Purslane has shown analgesic, antispasmodic, skeletal muscle relaxant, bronchodilator, antiasthmatic, anti-inflammatory, antiseptic, diuretic, antibacterial, antipyretic, and wound-healing properties. In addition, purslane's hypoglycemic and hypolipidemic properties have been reported in different studies. The positive effects of this plant include reducing stress oxidative and inflammation along with the atherogenic index, improving insulin level and glucose uptake, decreasing lipid profiles, and ameliorating weight gain. These activities could reduce MetS complications. This review aims to provide a comprehensive overview of various in vitro, animal, and human studies regarding the effect of Portulaca oleracea on metabolic syndrome to better understand the underlying mechanisms of action for designing more effective treatments.

Abstract
Diabetic mellitus (DM) is a common metabolic disorder prevailing throughout the world. It may affect a child to an older person depending upon the physiology and the factors influencing the internal metabolic system of the body. Several treatments are available in the market ranges from synthetic drugs, insulin therapy, herbal drugs, and transdermal patches. Interestingly, the development of technologies and digital health have proving very helpful in improving the lifestyle of diabetic patients. All treatment approaches have their own advantages and disadvantages in the form of effectiveness and side effects. Medicinal plants have a long history of traditional application in the treatment of diabetes and even the use of plants are growing day-by-day due to the significant results against diseases and fewer side effects as compared to other treatment therapies. The intention behind writing this review is to gather all information and discussed them exhaustively in an article. The novel Coronavirus 2019 (COVID-19) pandemic has affected my lives including diabetic patients. The antidiabetic treatment strategies during this period has also discussed. In this article, we highlighted the molecular mechanism and herbal phytoconstituents that are responsible for lowering blood glucose level. The factors responsible for the progression of metabolic disorders can be controlled with the use of phytoconstituents present in herbal plants to maintain β-cells performance and restore blood glucose level. It can be concluded that medicinal plants are effective and affordable with lesser side effects for treating DM.

Abstract
Glucagon like peptide-1 (GLP-1) plays a major role in the regulation of energy homeostasis as it causes satiety and suppresses appetite. Angelica dahurica, Coreanomecon hylomeconoides, Chrysanthemum morifolium, Portulaca oleracea, Stellaria alsine, and Stellaria media have traditionally been used as famine relief foods in Korea. The aim of the present study was to determine whether the aqueous ethanolic extracts of the six plants stimulate GLP-1 secretion. The results demonstrated that each extract of the plants stimulated GLP-1 secretion from enteroendocrine NCI-H716 cells, respectively. Among the extracts examined, the extract of Portulaca oleracea showed the highest activity on GLP-1 release. The results may suggest that the GLP-1 secretion induced by the six plants is a possible mechanism for the six plants exerting effects on satiety increase and appetite suppression.

The effect of purslane seeds on glycemic status and lipid profiles of persons with type 2 diabetes: A randomized controlled cross-over clinical trial. JOURNAL OF RESEARCH IN MEDICAL SCIENCES : THE OFFICIAL JOURNAL OF ISFAHAN UNIVERSITY OF MEDICAL SCIENCES 2015; 20:47-53. [PMID: 25767522 PMCID: PMC4354065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/19/2014] [Revised: 09/23/2014] [Accepted: 12/01/2014] [Indexed: 11/24/2022]
Abstract
BACKGROUND We are aware of limited data about the effects of purslane on diabetes. Earlier studies have mostly indicated the beneficial effects in animal models. This study aimed to evaluate the effect of purslane seeds on glycemic status and lipid profiles of persons with type 2 diabetes. MATERIALS AND METHODS This cross-over randomized controlled clinical trial was conducted on 48 persons with type 2 diabetes. Participants were randomly assigned to receive either 10 g/day purslane seeds with 240 cc low-fat yogurt (intervention group) or only 240 cc low-fat yogurt (as a control group) for 5 weeks. After a 2-week washout period, subjects were moved to the alternate arm for an additional 5 weeks. At baseline and end of each phase of the study, fasting blood samples were collected to quantify plasma glucose levels, as well as serum insulin and lipid profiles. Within-group and between-group changes in anthropometric measures, as well as biochemical indicators, were compared using a paired-samples t-test. RESULTS Mean age of study participants was 51.4 ± 6.0 year. We found a significant reduction in weight (-0.57 vs. 0.09 kg, P = 0.003) and body mass index (-0.23 vs. 0.02 kg/m(2), P = 0.004) following purslane seeds consumption. Despite a slight reduction in fasting plasma glucose levels (-2.10 vs. -2.77 mg/dL, P = 0.90), we failed to find any significant effect on serum insulin levels and homeostatic model of assessment of insulin resistance score. Furthermore, purslane consumption decreased serum triglyceride levels (-25.5 vs. -1.8 mg/dL, P = 0.04) but could not affect serum high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and total cholesterol levels. We observed a significant reduction in systolic blood pressure (-3.33 vs. 0.5 mmHg, P = 0.01) and a borderline significant decrease in diastolic blood pressure (-3.12 vs. -0.93 mmHg, P = 0.09) after purslane seeds intake. CONCLUSION In summary, consumption of purslane seeds for 5 weeks in persons with type 2 diabetes might improve their anthropometric measures, serum triglyceride levels, and blood pressure. Further studies are required to determine the appropriate dosage for these patients.
