As far as I know goat's rue does not contain any phytoestrogens. Here is some more info:

Cancer research has revealed that one of Goat’s Rue's primary chemical components directly affects estrogen receptors. This may be why it acts as an estrogen enhancer, without containing any known phyto-estrogens. Studies suggest that it actually encourages ovaries to produce their own estrogen.

But I am not sure if topical GR tincture is effective.
