a The mRNA expression level of α-lactalbumin (LALBA), b Aquaporin 1 (AQP1), c Aquaporin 3 (AQP3), and d Aquaporin 5 (AQP5) in mammary gland tissues of lactating Wistar rats using quantitative Real-Time Polymerase Chain Reaction (qRT-PCR) analysis at the end of treatment. The polyherbal formula (PHF) containing Sauropus androgynous Folium (300 mg), Trigonella foenum-graceum (150 mg), and Moringa oleifera Folium (150 mg). The negative control group of rats was orally administered distilled water; treated groups were orally administered 26.25, 52.5, and 105 mg/kg/day of PHF, respectively. A positive control group was treated orally with 2.7 mg/kg/day of domperidone. All the PHFs were administered to the mother rat groups from the 3rd to the 15th day of parturition. Values are expressed as mean ± SEM. (*p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001)
