The oestrogen receptor sites in the breast are stimulated by low doses of the plant-based oestrogen’s or phytoestrogens, combined with other natural substances drawn from the ERDIC ingredients. The effects are similar to those experienced by women during puberty or pregnancy. The phytoestrogens mimic the effects of oestrogen when introduced into the human body and this helps stimulate breast tissue growth. Phytoestrogens more closely match the body's own hormones yet have only 1/1000th the oestrogenic activity of synthetic or environmental oestrogen.
