There is certainly a wide variety of things suggested for treatment of menopausal symptoms. We all know that "natural" does not mean safe (or effective) but often these things are confused and played upon. The so-called division between "conventional" and "alternative" medicine is largely an illusion.
To my mind there are things that have been appropriately tested and found to be effective and acceptably safe (everything has risk) and there are things that have not. Unfortunately for people having to make decisions about their health the lack of testing of various supplements, herbal/plant derivatives and so on, leaves them in a quandary. They often have to make these decisions based on heresy of effectiveness and an almost complete lack of reliable safety information. So, for example, there have been cases of severe liver damage with black cohosh products.
This is coupled with problems such as lack of standardisation of the amounts of the putative active ingredient present in the product and even between different batches of the same product. That isn't to say that any particular remedy should be avoided, just that the information to make a risk/benefit decision is incomplete. Because "conventional" medicines have to be researched in a way that measures effectiveness and risk the picture is far more complete and people can have a better idea of what to expect on average. So whilst this still has limitations and imperfections it is a far better position to be in.
There are lots of good suggestions in the responses so far: non-drug measures and adaptations, pointers to the variety of drug treatments that may help specific problem symptoms, and avenues to explore for other remedies - my only caution being to gather sufficient information.
There is other good quality information out there on Patient UK, NHS Choices, Clinical Knowledge Summaries on options, e.g.:

https://www.nhmrc.gov.au/_files_nhmrc/publications/attachments/wh37.pdfAlso worth noting that whilst there are people who advise on other remedies they can still only operate from the available knowledge. For example drug interaction studies have not been done for many of these products, making it very difficult to give definitive advice on whether they could clash with other medications. Again that isn't to say they should be avoided, just that this should factor in to any decision.
Hope some of that helps.
