Unleashing the Potential of Medicinal Plants in Benin: Assessing the Status of Research and the Need for Enhanced Practices. PLANTS (BASEL, SWITZERLAND) 2023; 12:1506. [PMID: 37050132 PMCID: PMC10097054 DOI: 10.3390/plants12071506] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 03/25/2023] [Accepted: 03/27/2023] [Indexed: 06/19/2023]
Abstract
Medicinal plants play a crucial role in the primary health care of the population in developing countries such as Benin. The national universities of Benin conduct research on the pharmacological, toxicological, and phytochemical properties of these plants, but the resulting knowledge often does not lead to the development of phytomedicines for the improvement of public health. This study aims to assess the current status of research on medicinal plants in Benin. A literature review was conducted using various search engines, and the collected data was analyzed. The results indicate that research on the biological properties of medicinal plants is still in its early stages, with limited and inadequate methodological approaches. These limitations highlight the urgent need to enhance research practices and facilitate the development of effective and safe phytomedicines.

[PMID: 35431967 PMCID: PMC9006177 DOI: 10.3389/fphar.2022.792794] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Accepted: 02/28/2022] [Indexed: 12/18/2022] Open
Abstract
Cardiometabolic disorders (CMD) have become a global emergency and increasing burden on health and economic problems. Due to the increasing need for new drugs for cardiometabolic diseases, many alternative medicines from plants have been considered and studied. Moringa oleifera Lam. (MO), one of the native plants from several Asian countries, has been used empirically by people for various kinds of illnesses. In the present systematic review, we aimed to investigate the recent studies of MO in CMD and its possible mechanism of action. We systematically searched from three databases and summarized the data. This review includes a total of 108 papers in nonclinical studies and clinical trials of MO in cardiometabolic-related disorders. Moringa oleifera, extracts or isolated compound, exerts its effect on CMD through its antioxidative, anti-inflammatory actions resulting in the modulation in glucose and lipid metabolism and the preservation of target organ damage. Several studies supported the beneficial effect of MO in regulating the gut microbiome, which generates the diversity of gut microbiota and reduces the number of harmful bacteria in the caecum. Molecular actions that have been studied include the suppression of NF-kB translocation, upregulation of the Nrf2/Keap1 pathway, stimulation of total antioxidant capacity by reducing PKCζ activation, and inhibiting the Nox4 protein expression and several other proposed mechanisms. The present review found substantial evidence supporting the potential benefits of Moringa oleifera in cardiovascular or metabolic disorders.

Abstract
In the last few decades, Moringa oleifera, a multipurpose medicinal plant (MMP) has received increased research attention and commercial interest for its nutritional, therapeutic and pharmacological properties. Rigorous approaches including biological assays, animal and clinical trials are required towards safe usage as herbal therapy. We conducted a systematic review of the known pharmacological activities, toxicity, and safety of M. oleifera, usually used locally in the treatment and prevention of myriads of illnesses. Five major bibliographic databases (SCOPUS, Web of Science, Science Direct, PubMed, and Mendeley) were searched for studies reported on pharmacological activities, toxicity, and safety assessment of M. oleifera in the last 29 years (1990 – 2019). Studies on animals and humans involving aqueous leaf extracts and different preparations from M. oleifera seed and bark were also considered. All articles retained, and data collected were evaluated based on the period of the article, country where such studies were conducted and the document type. Our search results identified and analyzed 165 articles while 63 studies were eventually retained. Diverse pharmacological activities including neuroprotective, antimicrobial, antiasthmatic, anti-malaria, cardioprotective, antidiabetic, antiobesity, hepatoprotective and cytotoxic effects, amongst others, were recorded. Toxicity studies in animal models and few human studies showed that M. oleifera is safe with no adverse effect reported. The importance of the plant is highlighted in the search for new bioactive compounds to explore its therapeutic potentials towards drug discovery and development in the pharmaceutical and allied industries.

Abstract
Objective To evaluate the preventive effects of Moringa oleifera on metabolic syndrome (MS) in male Wistar rats. Methods MS was induced by feeding rats a high-fat diet and drinking water containing 10% fructose for 6 weeks. In the preventive group, M. oleifera was orally administered for 3 weeks prior to the induction of MS, while in the treatment group, M. oleifera was administered for 3 weeks after the onset of MS. The treatment groups were compared with a control group of untreated rats with induced MS. Fasting glucose, oral glucose tolerance, insulin tolerance, total cholesterol, triglycerides, abdominal circumference, and systolic and diastolic blood pressure were measured before and after MS induction and/or M. oleifera treatment. Results After the induction of MS, the control group had higher fasting glucose levels than the preventive group. No significant differences were observed in insulin tolerance, oral glucose tolerance, cholesterol, triglycerides, abdominal circumference, or systolic or diastolic blood pressure. Compared with untreated controls, rats in the treatment group had significantly improved glucose tolerance, triglycerides, and abdominal circumference. Conclusions M. oleifera treatment attenuates MS in Wistar rats.

Effect of Moringa oleifera Leaf Capsules on Glycemic Control in Therapy-Naïve Type 2 Diabetes Patients: A Randomized Placebo Controlled Study. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 2017:6581390. [PMID: 29317895 PMCID: PMC5727834 DOI: 10.1155/2017/6581390] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/30/2017] [Accepted: 11/06/2017] [Indexed: 11/30/2022]
Abstract
Background Studies showed effects of Moringa oleifera (MO) on lowering blood sugar levels in animal and diabetes patients. The aims of this study were to determine the effect of MO leaf capsules on glucose control in therapy-naïve type 2 diabetes mellitus (T2DM) and to evaluate its safety. Method This was a prospective randomized placebo controlled study. Therapy-naïve T2DM was randomly assigned to receive either 8 grams per day of MO leaf capsules (MO leaf group) or placebo for 4 weeks. Clinical and laboratory characteristics were recorded at screening and at the end of 4-week study. 9-point plasma glucose was obtained before and every week during the study. Results Thirty-two T2DM patients were enrolled. The mean age was 55 years and the mean HbA1C was 7.0%. There was no significant difference in FPG and HbA1C between groups. MO leaf group had SBP reduction by 5 mmHg as compared to baseline but this difference had no statistical significance. There were no adverse effects of MO leaf. Conclusions Moringa oleifera leaf had no effect on glycemic control and no adverse effects in T2DM. Interestingly, this study demonstrated that MO leaf had a tendency on blood pressure reduction in T2DM, and this result needs further investigation.
