Effectiveness of moringa oleifera to enhance the haemoglobin concentration in body: A systematic review

Abstract

Background: Moringa oleifera is a tree famous due to its various medicinal properties. However, studies have shown contradictory results. Objective: The objective of this review is to evaluate the effectiveness of Moringa oleifera on the haemoglobin concentration. Methodology: We have searched all the data from Google Scholar and PubMed. Data was retrieved from the articles published during 2018 -2023. We selected the articles on the basis of positive efficacy of moringa oleifera on the concentration of haemoglobin. Initially 107 studies were identified out of which just 10 RCT were shortlisted for the detail evaluation. In the included RCT, Moringa was administered during the low haemoglobin levels in the form of leave powder capsules, biscuits, cakes and bread. It appears to influence on haemoglobin levels and nutritional deficiencies. To monitor its dose dependent effect further studies are needed. Results: Total 107 studies were selected. However, after critical assessment 10 studies were shortlisted for this review. These studies ranged from the year 2013 to 2022. Among these studies, 2 (20%) were published in 2022, 2020, 2018 and 1 (10%) each from 2021, 2019, 2017, 2013. Moringa leaves are rich in nutrients, beneficial to maintain the good nutritional status and increasing Hb levels. Conclusion: Moringa Oleifera appears to be a useful for the prevention and treatment of nutritional deficiencies and increases in haemoglobin levels. To monitor its dose dependent effect further studies are needed. Keywords: Moringa Oleifera, Haemoglobin, anemia, Iron, deficiency, Dietary supplements
