Estrogen is quite a precious hormone for women. Even though guys have a small amount of this feminine hormone, us women have a lot more which makes us well, er - women. We also have a small amount of the male hormone testosterone in us as well, it's just that it is minimal compared to our sex-dominant hormones.
Estrogen makes women's skin softer than a man's, it causes us to develop soft, larger, feminine breasts, it makes our lips larger, and it causes us to have less muscle as well as less body hair - all traits of the female sex in the human world.
When you take estrogen away, it can cause a lot of side effects that not only make you feel less feminine, but also that can cause mood swings and depression. This is why many women have such a hard time dealing with menopause, which is the time in a woman's life when her natural estrogen levels begin to severely decline.
Many herbal supplements for breast enhancement offer what is called "phytoestrogenic" compounds, which are plant-derived compounds that mimic the hormone estrogen in the female body. This can lead to more feminine characteristics, such as softer, larger breasts, less hot flashes, and other typical side effects of again having enough estrogen in the body.
With the decline of popularity of medical HRT (Hormone Replacement Therapy) which is the use of synthetic estrogen to get the levels back up in a woman's body, many women turn to plant based options. HRT got a bad name when it was linked to heart and stroke issues as well as a potential boost in the likelihood of breast cancer.
