Medicinal plants with potential antifertility
activity- A review of sixteen years of herbal


The seeds of Queen Anne's lace (QAL)
(Daucus carota) also known as Wild
Carrot, seem to have the best reputation
for contraception. Women from the
Appalachian Mountains to India have
used the mature seeds to reduce their
fertility. This herb is in use today, and
has some documentation to its
effectiveness, both in scientific studies
and through individuals who have used
it. QAL seed seems like a good
reliable option. It does not need to be
used daily to be effective. If a woman
knows she was exposed to sperm during
a fertile time, QAL seeds can be used
like an emergency contraceptive, an after
the fact preventive. One of its biggest
advantages is that it can be taken on as
needed basis, making it useful for
women who have sex in frequently
The plant also grows wild in many areas,
though positive identification is a must.
Scope out patches while the flower is in
bloom in August and return later to
collect the seeds. To the inexperienced,
wild carrot could be confused with other
poisonous members of the carrot/parsley
family. Once familiar with the plant it is
easy to identify, the flower in bloom is
very distinctive, and just remembers
Queen Anne has hairy legs (the stem is
hairy rather than smooth).
Rutin - This is found at local health food
markets. It is also known as Vitamin P.
It can be used to prevent pregnancy,
when taken in tablet form in doses of at
least 500 mg daily for several days
preceding and following ovulation, or
when taken after intercourse and
continue until menstruation begins."

Abstract Ancient literature mentions the use of a number of plants/preparations for fertility regulation. Some local contraceptive agents have also been described in Ayurvedic and Unani texts. Documented experiments or clinical data are, however, lacking. Therefore, the present study was undertaken to explore the antifertility and estrogenic activity of ethanolic extract of the roots of Hibiscus rosa-sinensis Linn. A strong anti-implantation (inhibition 100%) and uterotropic activity was observed at the dose level of 400 mg/kg body weight. Histological studies were carried out to confirm this effect.

Wild Carrot

Moderate Interaction Be cautious with this combination

  • Estrogens interacts with WILD CARROT

    Large amounts of wild carrot might have some of the same effects as estrogen. But wild carrot isn't as strong as estrogen pills. Taking wild carrot along with estrogen pills might decrease the effects of estrogen pills.
    Some estrogen pills include conjugated equine estrogens (Premarin), ethinyl estradiol, estradiol, and others.

  • Lithium interacts with WILD CARROT

    Wild carrot might have an effect like a water pill or "diuretic." Taking wild carrot might decrease how well the body gets rid of lithium. This could increase how much lithium is in the body and result in serious side effects. Talk with your healthcare provider before using this product if you are taking lithium. Your lithium dose might need to be changed.

  • Medications for high blood pressure (Antihypertensive drugs) interacts with WILD CARROT

    Large amounts of wild carrot seem to increase blood pressure. By increasing blood pressure wild carrot might decrease the effectiveness of medications for high blood pressure.
    Some medications for high blood pressure include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), amlodipine (Norvasc), hydrochlorothiazide (HydroDiuril), furosemide (Lasix), and many others.

  • Medications that increase sensitivity to sunlight (Photosensitizing drugs) interacts with WILD CARROT

    Some medications can increase sensitivity to sunlight. Wild carrot might also increase your sensitivity to sunlight. Taking wild carrot along with medications that increase sensitivity to sunlight could increase the chances of sunburn, blistering or rashes on areas of skin exposed to sunlight. Be sure to wear sunblock and protective clothing when spending time in the sun.
    Some drugs that cause photosensitivity include amitriptyline (Elavil), Ciprofloxacin (Cipro), norfloxacin (Noroxin), lomefloxacin (Maxaquin), ofloxacin (Floxin), levofloxacin (Levaquin), sparfloxacin (Zagam), gatifloxacin (Tequin), moxifloxacin (Avelox), trimethoprim/sulfamethoxazole (Septra), tetracycline, methoxsalen (8-methoxypsoralen, 8-MOP, Oxsoralen), and Trioxsalen (Trisoralen).
