pueraria mirifica by its self is fine

I'm only looking at the research I can find. It does look very good.
Up till this point though it looks to me like you need an extra aromatase booster at the least unless you already have a lot of aromatase. The easiest aromatase booster is alcohol then genistein and peony root.

Revisiting, however, it does look like it also does inhibit 5-a-r in addition to converting testesterone back to andrestenedione so at the very least it's not going to masculinize you (because it will be eliminating DHT).

I'd say from it's effects on enzymes that (aromatase notwithstanding) it probably does work better than other so called feminizing herbs.

Follow up: after doing some research on how spironolactone works on the body's steroid system it looks like PM in part acts like a slightly weaker version of spiro and spiro can allegedly feminize all by itself too.
