Nutritional and Therapeutic Potential of Shigru (Moringa Oleifera) in Rasavaha and Raktavaha Srotodushti: A Scoping Review of Iron and Haematological Outcomes

Abstract

Rasavaha and Raktavaha Srotodushti are important pathological entities in Ayurveda associated with impaired tissue nourishment, reduced Rakta formation, fatigue, pallor, and diminished vitality. Iron deficiency and depleted ferritin stores are among the leading causes of anaemia worldwide. Moringa oleifera (Shigru) is rich in micronutrients, antioxidants, polyphenols, vitamins, and minerals that may improve haematological parameters. Although most published studies evaluate moringa leaves, Ayurvedic texts also describe medicinal properties of Shigru. Aim & Objective: To review the available literature regarding the role of Shigru (Moringa oleifera) in amending Rasavaha and Raktavaha Srotodushti with special prominence on haematological parameters along with serum iron and ferritin. Methods: A systematic search of PubMed, Scopus, ScienceDirect, the Cochrane Library, Google Scholar and the AYUSH Research Portal was undertaken in accordance with PRISMA guidance. Studies involving human participants were considered eligible when they examined the effect of moringa supplementation on haematological outcomes. Eligible publications included randomised controlled trials, non-randomised clinical trials, quasi-experimental investigations and relevant systematic reviews. Results: Actual evidence demonstrates improvement in haemoglobin concentrations following moringa supplementation, particularly among women, adolescents, and children with iron deficiency. Evidence for improvement in serum ferritin is promising but remains limited due to heterogeneity in study designs, dosages, preparations, and durations. Most available evidence concerns leaf preparations rather than fruits. Conclusion: Shigru may support Rasa–Rakta Dhatu Poshana and haematological health. However, the current evidence primarily concerns moringa leaf preparations. Well-designed trials using standardised Shigru Churna are needed to assess serum iron, ferritin and relevant Ayurvedic outcomes.
