It is a problem all the way around, isn't it, both for the heath of the woman and the health of the nation and world. It is worse in this situation because new products are introduced with hype and old ones go away and a person often doesn't know until they read news reports of women having trouble with new products if they are lucky enough to hear about them.
These days we have the internet and we can Google reviews for individual products. Whether they are trustworthy of not is another problem. I Googled this and almost always leave documentation with my answers. In this case I do not have a source that I trust for effectiveness.
I use Consumer Reports for things like soaps, etc. because they are pretty good about taking things like being green into consideration along with other things that have to be considered also. That works here also. The local library is my source for the reports. That is the best and safest way I know.
An organic label is a help, but that is not infallible.
