I found this on chrysin. Not specifically what you posted.
"Further evidence of chrysins lack of effectiveness in inhibiting aromatase is found in an article in JAMA several years ago.15 Researchers tested an androstenedione product, fortified with chrysin, to determine if chrysin would prevent estradiol levels from increasing. It didnt.
Another study to evaluate the aromatase-inhibiting ability of chrysin was conducted by scientists at the Institute of Biomedicine in Turku, Finland.16 The scientists administered chrysin to rats at a dose of 50 mg/kg body weight, which is considerably more than is found in human diets or dietary supplements (thats about 3.5 grams, human equivalent). The scientists found that chrysin had no ability to inhibit aromatase in these intact animals, hypothesizing that the lack of in vivo efficacy was due to poor aborption or bioavailablity."
