Scotch Broom (Cytisus scoparius) has a history of traditional use in European herbal medicine, including applications related to uterine health. Traditionally, various parts of the plant, particularly the flowering tops, have been used to address uterine bleeding and to support uterine tone. Folk medicine texts from the 18th and 19th centuries reference the use of Scotch Broom as an emmenagogue (to promote menstrual flow) and as an aid for uterine atony (lack of muscle tone).

The active constituents believed to be responsible for these effects include alkaloids such as sparteine, which can affect smooth muscle tissue. However, scientific research on the efficacy and safety of Scotch Broom for uterine health is extremely limited. There are a few older pharmacological studies that document the uterotonic (uterus-contracting) properties of sparteine in animal models and isolated tissue, but these findings have not been robustly evaluated in modern clinical trials or systematic reviews. Furthermore, due to the potential toxicity of alkaloids in Scotch Broom, its use is not recommended in pregnancy or without medical supervision.

In summary, while there is a historical and traditional basis for the use of Scotch Broom in supporting the uterus, there is little contemporary scientific evidence to validate its efficacy or safety for this purpose.
