Most of us have heard the warnings, “Don’t take herbs into pregnancy!” Along with avoiding alcohol, certain prescription medications and illicit drugs, most herbs should be avoided in pregnancy as well. So what should you do if have been following an herbal program and find out you are pregnant? Should you stop taking the herbs suddenly? Can herbs cause you to miscarry? Can herbs harm a developing fetus? Pregnancy happens a lot around here, we want you to handle the situation with ease and the know-how to move forward with a healthy, full-term pregnancy!
Important: It is always best to avoid herbs in pregnancy, unless directed to use certain ones by your healthcare practitioner. In some cases a woman will choose to continue herbs and supplements into pregnancy while under the care of a skilled herbalist, natural healthcare practitioner or doctor. Please always find a qualified healthcare practitioner to work with before choosing to continue herbs into pregnancy.
1. Q: Can herbs cause a miscarriage if they are stopped suddenly?
A: Potentially. Some herbs may elicit a hormone like effect, or have an action on the hormones in the body. If you have been taking herb/s and you are still taking it/them in pregnancy, you need to make a plan of how to wean off of that herb slowly, over time, so as to not disrupt the natural hormonal cycle of the pregnancy. Suddenly stopping some herbs in pregnancy may potentially cause a miscarriage due to hormonal disruption.
A good way to wean off of an herb or herbal blend is to take less and less each day, over a week. If you are taking herbs in a capsule form, you could open the capsule, dump a little out and then close it back up and then take it. Do this each day until you are no longer taking it. If you are taking a tincture (liquid extract), take fewer drops each day. Tablets will potentially need to be cut in half. Infusions or decoctions will need to be cut down in cups. So if you are drinking 3 cups a day, cut down to two cups for a few days, then to one and so on.
If you have a history of recurrent miscarriage, it is especially important to seek guidance for weaning off of herbs. Special considerations need to be made whenever there is a history of progesterone deficiency, uterine weakness, recurrent miscarriages, or other health related issues that may affect pregnancy. Seek the guidance of a qualified healthcare practitioner, someone to help guide you through this transition.
2. Q: Can herbs harm my unborn baby?
A: Some herbs, when taken in high amounts therapeutically, or long-term could potentially harm your baby when taken in pregnancy. To be honest there is little research on the subject and most information comes about when a problem arises. For example, a baby born is born with an abnormality and through research it is found that the mother’s had taken herbs in pregnancy. These cases are then documented. The herb is noted as a potential risk to pregnancy. But, typically this never happens.
Most women do not want to be part of human pregnancy trials, that is why there is limited research on the subject. In fact, most medications are not tested for safety in pregnancy. In general, doctor’s suggest they all be avoided when possible. Better to be safe than sorry is the general rule of thumb, in most cases.
Some information comes from animal studies, mostly on rats. Researchers use this information to help determine if an herb is safe in pregnancy or not. The problem with most of these studies is that the researchers give the rats concentrated, excessive amounts of the herb or an isolated part of the plant intravenously. The animals are given the herb throughout pregnancy. When a negative result on the animal fetus’ is shown, the herb will be deemed unsafe for pregnancy. Realistically though, no human being is going to take an herb the way the animals in studies are given herbs.
Before choosing any herbs for pregnancy preparation, or for pregnancy it is very important to learn if it is safe in pregnancy or not. Learn about the safety of preconception herbs in pregnancy here…
3. Q: I got pregnant while doing the Fertility Cleanse, will the cleansing pass toxins on to my baby? Will the herbs harm my baby?
A: It takes 7-10 days for a fertilized egg to move to the uterus for implantation. If you got pregnant while doing the Fertility Cleanse, it is highly unlikely that any toxins will be passed on to your baby. This is because you will have finished the herbs before the placenta has developed. If you find out you are pregnant while still doing the Fertility Cleanse Kit, discontinue them. You could wean off of them over a few days if you are worried about their action on the uterus. There are some herbs in the Fertility Cleanse that have an action on the uterus, therefore you would not want to continue them into pregnancy. Some herbs cause uterine contractions, or are irritating to the uterus, which may potentially cause a miscarriage if continued more than a week or two. This is why we never suggest trying to conceive while doing the Fertility Cleanse.
4. Q: I have been using herbs to prevent miscarriage, should I stop them suddenly or wean off of them?
A: Contact an herbalist, naturopathic doctor or midwife trained in herbal medicine and ask them for guidance. Hopefully you are already working with a natural healthcare practitioner who is suggesting herbs that are safe for pregnancy, at the proper dosage and length of time for use. Never stop them suddenly, again weaning off over time is best. The general approach is to continue your herbal miscarriage prevention protocol until at least 2 weeks past the last weeks’ gestation of the previous miscarriage (if the previous miscarriage occurred at 8 weeks, continue the formula until at least 10 weeks). Remember, it is extremely important to work with an herbal practitioner, someone who can monitor your herbal program.
5. Q: I have been using natural progesterone cream to prevent miscarriage and I am nearing my 20th week. Should I just stop using the cream one day, or wean off slowly?
A: By the 20th week of gestation, the placenta should take over progesterone production. At this point there should be no need to continue on with natural progesterone cream, unless you are suggested to do so by your midwife or doctor. It is fine to stop the cream any time after the 20th week. It does not matter if it is suddenly stopped or not. If you are worried, you would wean off over a couple of days. If you have a history of miscarriage due to low progesterone and you are worried, talk to your healthcare practitioner about your concerns about discontinuing natural progesterone cream.
6. Q: How can I find out if the herbs I am taking are safe for use in pregnancy or not?
A: The best way to find out is to write down a list of herbs you are interested in, or are currently taking. You can then take the list to your local herbalist, or call them to ask if they are safe or not. Books that have information on herbs that should not be used in pregnancy are:
Medical Herbalism The Science and Practice of Herbal Medicine by David Hoffmann, FNIMH, AHG. Page 394
Botanical Medicine for Women’s Health by Aviva Romm, MD. This book has a great list of herbs used for women’s health, with their safety for pregnancy and lactation from pages 553-611
The above books are more advanced and many of the herbs are listed by binomial name. Motherlove Herbal company has a great list of herbs to avoid in pregnancy by common name and action.
You can also look up each herb in an herb book and it will most likely tell you if the herb is safe for pregnancy or not. Most herbs are not suggested for pregnancy.
