The natural herbal ingredients found in most breast enhancement products each have their own use, but it's the combination of these herbs that make them beneficial.
For example, fennel seed, which is contained in some breast enhancement products contains flavonoids which impart a mild estrogenic effect. Other herbs such as dong quai is used for regulating hormonal balance.
The combination of all of the herbal ingredients is important, as they all act together to create phytoestrogens, which are estrogen-like substances in the body. These phytoestrogens act directly on the mammary glands, increasing growth in the breast tissue.
Natural breast enhancement supplements work for most women, increasing breast size by 1 to 3 cups. It does take several months to achieve maximum results - usually from 2 to 6 months. Most women are willing to wait a few months to get the natural results, something you don't get with breast implants!
