Pregnant women can eat longan, but they need to eat it in small amounts and it is best to avoid it in early pregnancy. Longan contains nutrients such as glucose, sucrose, vitamin A and vitamin B. It is rich in nutrients and has the effect of tonifying the heart and calming the mind, nourishing the blood and benefiting the spleen, and is suitable for people who suffer from deficiency of qi and blood, weakness, dizziness and tinnitus, menstrual disorders and postpartum sweating. According to Chinese medicine, longan is warm and sweet in nature, which can easily fuel fire. Excessive consumption of longan can easily lead to qi imbalance in pregnant women, causing stomach gas rebellion, vomiting, etc. In serious cases, it can cause abdominal pain and may even cause miscarriage. Because longan is warm and sweet, it can help fire and dryness, so it is not suitable for people with Yin deficiency and phlegm fire. After conception, most women have Yin and blood deficiency, and Yin deficiency breeds internal heat, so pregnant women often have dry stools, dry mouth and fetal heat, and heat in the liver. Excessive consumption of longan will not only fail to nourish the body, but will easily lead to redness, abdominal pain and other symptoms of pre-term abortion. Especially in early pregnancy, when the embryo is not yet stable, extra caution is needed to avoid consuming longan and its products. As mentioned above, pregnant women should eat longan in the right amount so as not to prevent the body from gathering blood to nourish the fetus. It is recommended to eat more light, easily digestible and nutritious fruits and vegetables, supplement vitamin C and ensure a balanced diet to avoid affecting the development of the fetus.
