well, they um....can be used to stimulate sexual arrousal in men and women. They also delay the start of Moon Cycles (helps if yours is irregular), they promote uterine contractions (not safe for preggos)and have been rumored to be an effective morning after type tonic. Now I can't find the site that info comes from, but I do have dried wild carrot leaves from my woods to safe for when the next baby is wanted (;) ) and for when that baby is born to aid in expelling his or her placenta....
Did you ever find the answer to your question? I have tons of carrots growing in my garden. It sounds like the carrot tops might help your body produce Oxytocine. If that is what it really does then I should probably eat them because Oxytocine helps with milk supply. :)
