Anise (Pimpinella anisum) has a long history of use in traditional medicine, particularly in Mediterranean, Middle Eastern, and South Asian cultures. It has been used to address various female reproductive issues, including promoting menstruation, alleviating menstrual discomfort, and supporting lactation. In folk medicine, anise seeds have been incorporated into teas and tonics intended to "strengthen the uterus," reduce cramps, and regulate menstrual cycles.

The rationale behind these uses is largely attributed to the plant's phytoestrogen content—compounds that can mimic estrogenic activity in the body. Some small-scale studies and animal research have suggested that anise extracts may have mild estrogen-like effects, potentially influencing reproductive tissues. However, robust clinical evidence in humans is limited, and most claims regarding direct uterine support stem from traditional practices rather than scientific validation.

Overall, while anise is traditionally used to support the uterus and women's reproductive health, there is insufficient high-quality clinical research to fully substantiate these effects. Its use for the uterus remains primarily grounded in traditional herbal medicine rather than in strong scientific evidence.
