It might be best to use pm alone to start then maybe add extra herbs separately too many additional weaker phytoestrogens will lower the benefit of pm. Or If she liked breast success another option could be to buy some of the main ingredient separate to get a higher dose breast success is only not a good product because its very expensive for weak low dose most people only get temporary swelling because of this.
There is a lot of good information on herbs and pm here take a little read.
