In late pregnancy, there is no such thing as fetus poison in western medicine. Chinese medicine believes that it is the internal heat of the pregnant woman, which causes the fetus to be prone to sores or rashes after birth. You can eat more fire-reducing foods, such as mung beans, corn husk boiled in water, and so on. In the late stage of pregnancy, the internal heat of pregnant women increases, which will easily lead to sores and acne rashes after the fetus is born. In order to prevent these symptoms from occurring, pregnant women can eat more fresh vegetables and fruits, eat a light diet, and drink more water, which can be more food such as mung bean soup and water boiled with corn husk. Do not self-medicate during pregnancy to avoid adverse reactions that may affect the pregnant woman and the fetus. If the pregnant woman is not unwell, there is no need to take medication to get rid of the fetus poison. After the baby is born, if the above symptoms occur, medication can be given with the help of a doctor and should not be used by oneself.
