It says that pumpkin seed extract was proven to be an effect aromatase and 5ar inhibitor in vivo and in vitro. The figures provided are rather astonishing, at least for the higher dosage of pumpkin seed extract, which inhibited 90% of type 2 5ar in the human prostate. The article goes on to say that, while phytosterols were thought earlier to be the active substance, perspective has shifted somewhat, as scientists realize that that these sterols are not easily absorbed. One researcher names phenolglycoside as a likely active agent.
