Deer antler, antler glue, walnut kernel, placenta and other properties warm and nourish yang, which will breed excessive internal heat, consume yin and hurt body fluid, and should not be taken by pregnant women. If it is really necessary, it should also be taken under the guidance of a doctor. Pregnant women can choose supplements and tonics according to the principle of "cooling before delivery".

Pregnant women should not eat more hawthorn.

Most women have pregnancy reactions when they are pregnant and like to eat sweet and sour things. But pay attention to hawthorn fruit and its products. Pregnant women should not eat. Modern medical clinic has confirmed that hawthorn has contractive effect on female uterus. If pregnant women eat hawthorn food in large quantities, it will stimulate uterine contraction and even lead to abortion. So pregnant women should not eat more hawthorn.

Pregnant women should use ginseng with caution.

Ginseng is a product that can greatly replenish vitality. If a woman takes it for a long time after pregnancy or the dosage is too large, she will be full of qi and exhausted. Yin deficiency leads to fire, that is, "qi is full of fire." Li Shizhen, a famous doctor in the Ming Dynasty, pointed out: "Ginseng warms qi, which belongs to yang, and yang is abundant and yin is dissipated." . It shows that improper use of ginseng can easily lead to yin deficiency and yang hyperactivity. An American doctor observed more than 100 people who took ginseng 1 month, and found that most of them had adverse reactions such as excitement, irritability, insomnia, sore throat and elevated blood pressure. He called this phenomenon "ginseng abuse syndrome" and thought that its mechanism might be related to neuroendocrine dysfunction. From the perspective of traditional Chinese medicine, these adverse reactions are actually manifestations of yin deficiency and excessive fire. In addition, people who take too much will have antidiuretic effect, which is easy to cause edema. It can be seen that the abuse of ginseng by pregnant women can easily aggravate the phenomena of vomiting, edema and hypertension during pregnancy, and can also promote vaginal bleeding and lead to abortion. From the fetal point of view, the tolerance of the fetus to ginseng is very low, and too much ginseng intake by pregnant women may cause stillbirth. A woman who is pregnant 1 month often eats ginseng. Palpitation occurred two weeks later, and the fetus died four months later. Therefore, pregnant women should not abuse ginseng.

Pregnant women should not eat glutinous rice liqueur.

Many places in China have the custom of drinking glutinous rice liqueur for pregnant women, and they mistakenly think that glutinous rice liqueur is something that "supplements the mother and strengthens the fetus". This statement has no scientific basis. On the contrary, it will cause fetal malformation. Glutinous rice liqueur, like ordinary wine, contains a certain proportion of alcohol. Different from ordinary liquor, the alcohol concentration of glutinous rice liqueur is not as high as that of spirits. However, even a small amount of alcohol can enter the fetus through the placenta without hindrance, hindering the division of fetal brain cells, leading to hypoplasia, and can cause the development of the central nervous system, leading to mental retardation and some fetal organ malformations, such as small head, small eyes, short chin, and even heart and limbs malformations.

Pregnant women should not eat stewed chicken with astragalus.

Pregnant women, especially those who are about to give birth, eat stewed chicken with Astragalus membranaceus, and many people cause overdue pregnancy, and the fetus is too large to cause dystocia. It is necessary to use lateral perineal incision, forceps to assist delivery, and even cesarean section to assist delivery, which brings pain to pregnant women and may also damage the fetus. Pregnant women eating stewed chicken with Astragalus membranaceus leads to dystocia, which is due to the effects of benefiting qi, lifting and astringent semen, which interferes with the physiological law of normal fetal decline in the third trimester of pregnancy. Astragalus membranaceus has the functions of "invigorating qi, strengthening bones and muscles, growing meat and enriching blood", while hens themselves are high-protein foods, which play a role in nourishing and enhancing efficiency, making fetal flesh and blood grow too fast and causing dystocia. Astragalus has diuretic effect. Through diuresis, amniotic fluid is relatively reduced, thus prolonging the labor process.
