It looks like it is referring to White Peony, and its constituents, but that needs verification.

It says "Paeoniflorin, glycyrrhetic acid and glycyrrhizin" reduce "testosterone production but did not change that of delta 4-androstenedione and estradiol." The next two sentences say it changes the ratios. It concludes, "These results suggest that paeoniflorin, glycyrrhetic acid and glycyrrhizin affect the conversion between delta 4-androstenedione and testosterone to inhibit testosterone synthesis and stimulate the aromatase activity to promote estradiol synthesis by the direct action on the rat proestrous ovary."
