If you visit an acupuncturist who specializes in traditional chinese medicine, they can make a herbal mix which DOES fix hormonal imbalance within women, regardless of age or any other factor, I have seen it work every single time with every female that has done it. Not one failure have I seen yet from them. They must be TCM qualified though, not just an acupuncturist.

Added: Not all TCM's are created equally either. There is a difference to just off the shelf herbal remedies compared to them mixing the things themselves too actual TCM specifications and taking into account the dynamics of the female themselves, being they are mixed to suit their body size, characteristics, strength of period, etc... not just off the shelf nonsense from a lazy TCM.
