Herbs and Essential Oils to Avoid During Pregnancy

 

Early pregnancy is a special time of growth for the fetus. During pregnancy, even some  normally benign herbs act in a negative way on the body. An example of a normally benign herb is aloe juice. It should not be used internally as a laxative during pregnancy because its purgative actions might create unwanted contractions. The same is true of rhubarb root. See essential oils and herbs listed below.

 

HERBS TO AVOID DURING EARLY PREGNANCY- Do not take these herbs in early pregnancy: raspberry leaf tea, fenugreek, vervain. It is safe and useful to use raspberry tea in the last two months of pregnancy, and to use the aerial parts of vervain to stimulate contractions during labor. In early pregnancy, do not use therapeutic amounts of these three normally benign herbs- sage, thyme, or fennel- although it is absolutely safe to use thyme, sage, and fennel in cooking during the entire pregnancy period.

 

ESSENTIAL OILS TO AVOID DURING PREGNANCY- Pennyroyal oil should be avoided at all cost. Many herbalists believe the herb itself can safely be used, and that pennyroyal has a bad reputation because the oil is dangerous in pregnancy. Other uterine stimulating essential oils that must be avoided are essential oils of basil, cinnamon, chamomile, myrrh, celery, and celery seed.

 

AVOID COMPLETELY- These herbs are uterine stimulators: angelica, (bark) elder tree, goldenseal, juniper, lavender, motherwort, primrose, rue, shepherd's purse, tansy, vervain (except during labor), and wood betony. The Chinese herb san qi, also called Panax notoginseng or pseudoginseng, has an adverse effect on the foetus. Note this is not Panax ginseng (Korean, Chinese ginseng) or Panax quinquefolius (American ginseng). Steroids and herbs containing steroid-like factors including Agave, Ginseng, Licorice, Ginger, Hops, Sage, Celery, Flax Seed, Soy products, Primrose, Black Cohosh, Sarsaparilla, Damiana, Saw Palmetto, and Dong Quai. Large amounts of oestrogen in the body can promote miscarriage.
