Bioidentical estriol cream is a hormone replacement therapy used to alleviate the symptoms of menopause. The cream contains estriol, a hormone that decreases during menopause, and works by stabilizing the level of this hormone in the body, according to the Harvard Women?s Health Watch.
At the onset of menopause, certain hormone levels begin to decrease causing symptoms such as hot flashes and night sweats. Commonly these symptoms are relieved by stabilizing hormones through a replacement therapy such as a bioidentical estriol cream, says Harvard Women?s Health Watch. Bioidentical estriol cream is applied to the skin, usually the forearms, allowing the hormones to be absorbed by the blood vessels. As the hormones are absorbed by the body, menopausal symptoms begin to subside.
Bioidentical hormones are produced from plant sources such as yams and soy, and they are molecularly identical to those found in the human body, notes Harvard Women?s Health Watch. Bioidentical hormones are often billed as a more natural alternative to previous hormone replacement therapies such as Premarin, a replacement produced using a pregnant mare?s urine, which are associated with an increased risk of cancer, blood clots, heart disease and stroke. While bioidentical hormones are synthesized in a lab, it is believed that these replacement therapies offer a safer alternative to the previous therapies.
