Prenatal vitamins are an important source of folate and other vital nutrients during pregnancy. And many women, with the popularity of herbal medicine, take other herbs during pregnancy. Some of these herbs they may have been taking before, for an existing condition. Others, they may take to help cope with some of the physical difficulties that go with pregnancy. The following supplements and food additives should be avoided during pregnancy to avoid potential problems with the health of the baby.
Now, this study was one done on rat embryos, and so may not translate into similar effects on humans. And it only studied the effects of one of ginseng's active constituents, which was a ginsenoside called Rb1. Ginseng actually has over 20 ginsenosides, and other studies have found that these each have different actions.
One of the difficulties with studying active constituents in herbal medicine is that the whole herbal extract may have a very different overall effect than a single constituent. This is because of the way active principles both work together and counteract each other. These two aspects, the fact that the study was not done on humans, and does not measure the overall effect of the whole ginseng extract, mean that its results should be treated cautiously. As a safety precaution, at this time it is best to at least avoid ginseng supplements during the first trimester, as the authors of the study suggest, and probably for the whole of the pregnancy. But ginseng should certainly not be branded dangerous as a result of this research as it is only a very preliminary finding in the overall picture, and more points the way as to where further research needs to be done.
