Hindi po, hindi sila pareho! Prolactin is a hormone na ginagawa ng pituitary gland, habang primrose (evening primrose) ay isang plant na may oil na commonly ginagamit for hormonal balance at reproductive health. A few of us mums take evening primrose during certain cycle phases kasi supposedly tumutulong sa fertility at hormonal stuff, pero yun ay supplement lang, prolactin is an actual hormone sa body mo na kailangan i-monitor ng doctor, lalo na if may concerns ka sa breastfeeding or menstrual issues. If you're concerned about your prolactin levels, best to ask your OB para may blood test at makita kung ano talaga ang nangyayari, kasi merong reasons kung bakit tumataas ang prolactin at need ng proper check-up.
