Fennel is a warm food. Pregnant women with yang deficiency can eat it in moderation, but pregnant women with constipation and excessive internal heat are not suitable for eating. It is more suitable for people with deficiency and cold constitution. If the constitution is overheated, it is necessary to eat less.
However, eating more fennel will have side effects that will damage vision, so it is not suitable for short-term large-scale use, and the upper limit should be 10 g per day. Pregnant women should eat fennel as little as possible and avoid fennel, which is a spicy and hot seasoning. It is easy to consume intestinal water and reduce the secretion of gastric glands, resulting in stomach pain, intestinal dryness, hemorrhoids, constipation or fecal obstruction. When constipated, pregnant women hold their breath hard to relieve constipation, which increases abdominal pressure. Pressing the fetus in the uterus is easy to cause fetal anxiety, premature rupture of amniotic fluid, spontaneous abortion, premature delivery and other adverse consequences.
