Does fennel increase milk production?

Generally speaking, fennel does not have the effect of promoting lactation. The detailed explanation is as follows:

The main nutritional components of fennel include vitamins, minerals, and dietary fiber. Although these nutrients can provide some of the necessary nourishment for postpartum women, there is currently no scientific research or clinical evidence indicating that fennel contains any components that directly promote milk production. It cannot stimulate lactation by regulating hormone levels or stimulating the mammary glands. Milk secretion primarily relates to factors such as prolactin levels, mammary gland development, nutritional intake, emotional state, and breastfeeding frequency. Relying on fennel to promote lactation may delay the implementation of effective lactation measures.

Although fennel does not promote lactation, it doesn't need to be completely avoided. It can be consumed in small amounts as a seasoning or side dish. However, excessive consumption should be avoided in the hope of increasing milk supply, as this may cause gastrointestinal discomfort or heatiness. If postpartum milk supply is insufficient, priority should be given to scientifically proven methods such as allowing the baby to frequently suckle to stimulate the mammary glands, ensuring adequate sleep and a positive emotional state, maintaining proper fluid intake, and seeking professional lactation guidance.
