Background: Since breastmilk is the healthiest nourishment for a newborn, the World Health Organization advises exclusive breastfeeding for a minimum of six months. But for a variety of reasons, including health conditions, hormone imbalances, and improper nursing techniques, a lot of mothers are unable to breastfeed. Mothers from lower socioeconomic backgrounds cannot afford medications, and many preferred fenugreek, banana plant, and moringa leaves, in a believed to increase breast milk production. Objective: To identify the effects of the banana stem diet on blood prolactin levels among post-natal mothers. Study design and methods: This protocol has been approved by PROSPERO and PRISMA guidelines will be followed. After completing the three steps, a literature search confined to English-language research articles published between 2008 and 2024 will be carried out. PICO phrases will be used to conduct a preliminary search in the Science Direct and PubMed-Medline databases. Study quality will be assessed using the Joanna Briggs Institute Manual (JBI) clinical assessment criteria. Two authors will assess independently, and any differences will be resolved. Result: The summaries will contain study-specific statistical data as well as narrative descriptions. Conclusion: This review will help to understand how banana stem diet supplementation helps in breastmilk production
