People have long noticed the healing properties of herbs and used them to treat and prevent many diseases. And now people continue to trust folk methods that have the least negative impact on the body, but only if used correctly.

Many women use such a well-known herb as St. John's wort for many disorders in the body. However, not everyone knows whether St. John's wort can be used during pregnancy.

St. John's wort is one of the most famous herbs in folk medicine, it is considered a cure for 99 diseases. In traditional medicine, St. John's wort has found its application as an antidepressant, with minimal side effects. St. John's wort contains substances such as tannin, hyperforin, flavonoids, hypericin, etc. Currently, the effect of St. John's wort on pregnant women and their children has been poorly studied, primarily due to the unsafe nature of such studies. But it has been scientifically proven that the substances contained in the herb can cause increased contraction of the uterus, which can lead to pathological processes in the development of the child or miscarriage. The substances contained in St. John's wort can have a negative effect on the central nervous system of the future baby, liver, and brain. It is for this reason that pregnancy and St. John's wort are incompatible. However, there is currently no reliable data on the safety of St. John's wort during pregnancy. Some laboratory studies have shown that high levels of St. John's wort in the body of mammals lead to significant genetic damage to the fetus. Other studies have found significant reductions in sperm motility, reduced ability to penetrate the egg, and, at very high concentrations of St. John's wort, disruption of DNA structure.

Mice given St. John's wort gave birth to babies that were much smaller than normal, but showed no significant developmental abnormalities. Another study gave St. John's wort to female rats, which resulted in them taking longer to complete a maze, but these studies raise some concerns.

The study also involved two women who took St. John's wort during pregnancy, and no serious abnormalities were found in either the mother or the child. However, scientists still recommend not to use St. John's wort during pregnancy or to take it with extreme caution, since its effect on the body during this period has been poorly studied.
