Chasteberry Tea may enhance the body's own regulatory action of the endocrine system, and particularly the "master gland", the pituitary gland. This gland, located at the base of the brain, is responsible for hormone release affecting such things as breast milk production and progesterone levels in women.
Chaste Tree berries appear to promote the release of breast milk by women who have recently given birth; but higher amounts can decrease milk flow. Chasteberry also has an important role to play in the maintenance of healthy reproductive tracts and menstrual cycles in women.
