Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Fennel (Foeniculum vulgare) has a long history of use in traditional medicine, especially in Mediterranean and Middle Eastern cultures, for addressing various women’s health concerns, including breast swelling and tenderness. The primary rationale for its use stems from fennel’s content of phytoestrogens—plant compounds that can mimic the effects of estrogen in the body. Traditionally, fennel seeds have been used to promote lactation, regulate menstrual cycles, and alleviate symptoms associated with menstruation, such as breast tenderness (mastalgia).

While anecdotal and ethnobotanical reports highlight fennel’s use for breast discomfort, scientific studies directly evaluating its efficacy for breast swelling and tenderness are limited. Some small studies and reviews have looked at fennel’s benefits for menstrual symptoms, and its phytoestrogenic action is biologically plausible for influencing breast tissue sensitivity. However, robust clinical trials specifically targeting mastalgia or breast swelling are lacking. Most evidence remains observational or based on traditional use patterns rather than rigorous scientific validation.

In summary, fennel’s application for breast swelling and tenderness is primarily rooted in traditional medicine, with supporting rationale from its phytoestrogen content but insufficient direct scientific proof. Further research is needed to clarify its efficacy and safety for this particular indication.
