In theory, Quantum Fem Balance could do what they say it does, but I take products like this with a grain of salt. Why? Look at the product itself. It has 15 herbs in it. Herbal medicine is no different from phramaceutical medicine in that the dosages are important. In fact, herbal medicine is much more complicated than pharmaceutical medicine because not only is the dosage important, but the part of the plant, the time of year it was harvested, how it was handled, and all aspects of extraction and processing are critical to how it performs. For example, Chaste Tree, one of the components of this product, can be awesome for increasing natural progesterone production in the female body, as well as possibly for helping control tremors in Parkinson's patients, but the chemical involved in the Parkinson's aspect is only present in the plant when it is harvested off-season.
Anyway, getting back to this stuff, it has 15 different herbs. Unless those are REALLY big capsules, or you have to take a LOT of them everyday, it is unlikely that you are getting any therapeutic dosage of any of them. That doesn't mean it can't work, but many American herb companies take an almost homeopathic approach to their products and neglect all of the science involved in these plants.
I routinely use herbs like Chaste Tree, Dong Quai, Wild Yam, Sage, Shatavari and others when balancing the female hormone system. When I do it, though, I use formulas that have actual therapeutic dosages of each herb, from manufacturers that I know do nothing but the best job in handling herbs and making their products. The shotgun approach to these herbal products is laughable because they put so much stuff in each tablet it makes for a nice read on the label to unsuspecting consumers, but makes herbalists or people in the know just roll their eyes.
So, yes, this product COULD work, but in my opinion, if you're interested in taking herbs, it pays to consult a real, practicing herbalist. When you need a prescription I doubt you head to the Black Market Back Alley pharmacy downtown with a self-diagnosis and a protocol and plan you developed yourself, right? Same should apply to herbs.
