This subject is very interesting, but I'm confused.

Aromatase is an enzyme that is needed to convert testosterone to estrogen in males. Which T is converted to which E? Is it free T that is converted to estradiol, or DHT?

To what extend are either Spearmint (which is anti-free T) or Pygeum (which is anti-DHT) going to complete with WP (a pro-aromatase herb whose purpose is to convert T to E)?

Also, to what extend is an aromatase promoting herb like White Peony interfering with PM? The theory is that estradiol and miroestrol compete for the same estrogen receptors in breast tissue. The more powerful estradiol, increases the risk of developing a malignant tumor in the breast. Miroestrol (the estrogen mimic in PM) is weaker, and by displacing estradiol, lowers the risk of cancer of the breast. Doesn't that mean that we should be favoring PM for NBE over pro-aromatase herbs like WP?

I hope some one can set me straight on this because I'm planning to make a change in my program next week (currently PM + Spearmint) by adding Pygeum (an anti-5 alpha reductase).

And, Lisa Lou, if you read this...you wrote that you're planning to replace SP with Spearmint+WP, right? What is your reasoning behind choosing WP over, say, Pygeum?
