Teas are prepared with medicinal plants that have active substances and, therefore, although they are natural, they have a high potential to affect the normal functioning of the body. For this reason, the use of tea and pregnancy should be done with great care, as they can affect the pregnant woman’s body and impair the baby’s development.
The ideal is that, whenever you want to use a tea during pregnancy, inform the obstetrician who is accompanying the pregnancy, to know the dosage and the most correct way to use that tea.
Because there are very few studies done with the use of plants during pregnancy in humans, it is not possible to state clearly which plants are completely safe or abortive. However, there are some investigations done in animals and even some cases reported in humans, which help to understand which plants seem to have the most negative effects on pregnancy.
