so:

1) Reduce testosterone conversion to DHT
2) Convert excess testosterone to estrogen

obviously the above scenario is not ideal for the estrogen-dominant, so another option may be increasing SHBG and reducing estrogen.

That's part of it, except in the case of estrogen dominance to influence proportionate amounts of (phyto) progesterone or prolactin. Progesterone and prolactin together lower and counter estrogen, and viceversa. They possibly break each other down into weaker, but effective hormones that don't bind to SHBG.

As for SHBG, insulin is the main thing to maintain.
