Microencapsulated Extracts From Banana Flowers Induce Milk Production in Lactating Rats Through Increased...

Musa sapientum L., commonly known as the banana flower (BF), is used as a galactagogue in Thai traditional medicine. This study aimed to assess the galactagogue potential of microencapsulated extracts from the BF and its impact on serum prolactin level, α-lactalbumin (LALBA), and aquaporin (AQP) protein levels in the mammary glands of lactating rats. Milk production was determined by measuring pup weight during the suckling period. The control group was administered distilled water orally, whereas Group II was administered domperidone at doses of 2.7 mg/kg. Groups III and IV were orally administered BF at doses of 250 and 500 mg/kg, respectively, from the 3^rd day to the 12^th day postpartum. On the 12^th day, blood samples and mammary gland tissues were collected for analysis. Protein levels of AQP-1, AQP-3, AQP-5, LALBA, and serum prolactin were assessed. Additionally, a histopathological examination of the mammary glands was performed. BF doses of 250 and 500 mg/kg were found to increase milk production, pup weight, serum prolactin levels, and protein levels of AQP-1, AQP-3, and AQP-5 compared to the control group. Transverse sections of the mammary glands from rats treated with 250 and 500 mg/kg exhibited a marked increase in milk secretion within the alveoli. These findings suggest that BF possesses significant galactagogue activity.
