Hi jaki
you're damned if you do and damned if you don't !!
Oestrogen can be beneficial in that it can help prevent bone loss/osteoporosis, it can improve deep sleep which in turn can help with muscle repair/recovery and give you more energy allowing you to excercise, it can improve mood which can lead you to being more active and eat more healthily rather than crave sugar or alcohol, and it can improve skin and hair allowing some women to feel better about themselves.
There is also some research that indicates that some women with fribromyalgia have benefitted from oestrogen therapy but you will have to obviously search the Internet to see that for yourself.
Yes there are risks - but each woman has to find the right balance .
You can't possibly know the risks with 'natural herbal therapy,' because they aren't researched or measured. Many natural remedies can be very potent especially when taken alongside prescription drugs.
