”Cold in the womb” is the natural equivalent of not having the sun in the sky. Cold and warmth are indicators of the foundation of a woman’s body. If the uterus is warm, the qi and blood in the body will run smoothly, and the periods will be regular, so that the “seeds” planted will develop into fetuses. If the uterus is not warm enough, the embryo will choose to grow in another place, leading to ectopic pregnancy. However, some gynecological acute and chronic inflammatory diseases (such as tubal inflammation, cervicitis, endometritis, adnexitis, etc.) commonly found in Western medicine can be treated with the identification of uterine cold, and very good results have been received in clinical practice, and these diseases are also the main causes of infertility. Chinese medicine treatment is mainly based on warming the menstruation and warming the uterus, and with acupuncture. In a broader sense, it includes the uterus, fallopian tubes and ovaries in the female internal genitalia. The “uterus”, “blood chamber” and “uterine organs” as they are called in Chinese medicine belong to this. The narrow sense of “cold” means that the uterus is cold, feeling cold, over-eating cold and cold, etc. The broad sense of “cold” includes the above, but also includes the female internal reproductive system (uterus, fallopian tubes, ovaries, etc.) and the low reproductive function of the yin and cold, yang energy, and kidney yang deficiency cold, as Chinese medicine says. Insufficient yin and yang energy, deficiency of kidney yang and cold, etc. Insufficient kidney yang in women, the uterus is not warmed by the lower abdomen, pain, heat will ease, leucorrhea, delayed menstrual cycle, low menstrual volume and black, blood clots, and even menstrual stoppage can not be; before or during menstruation abdominal pain, the pain can be relieved after the heat; leucorrhea thin amount; pulse sinking tight, light or dark tongue, thin white coating and more fluid as the main symptoms. Gong cold is the name of the disease in Chinese medicine. Chinese medicine believes that Gong cold is related to kidney deficiency, spleen qi deficiency, blood deficiency, liver depression, phlegm dampness, damp heat, blood stasis and other causes. There are many women with uterine cold in clinical practice and multiple clinical symptoms exist. It is true that a few women with uterine cold are infertile or will experience fetal growth retardation and embryonic abortion after pregnancy, which can lead to miscarriage in severe cases. This is because the reproductive environment of the uterus is affected by the coldness of the uterus, the growth and development of the fetus in a certain period, a certain stage lack of sufficient warm nutrition, the uterine cavity is always in a cold state, like the lack of sunlight, so the fetus development to a certain extent will no longer continue to grow and develop, that is, fetal abortion, miscarriage. Chinese medicine has obvious advantages in the treatment of “cold uterus” type infertility, mainly using a combination of “internal” and “external” treatment. Internal medicine is used to nourish the kidneys and warm the uterus, nourish the blood and warm the flush, and is taken orally once in the morning and once in the evening for 2-3 consecutive menstrual cycles; external treatment: moxibustion points, warm acupuncture, warming the uterus paste and other methods. Moxa, the medicine used in moxibustion, is pungent and warm in nature, and belongs to the liver, spleen and kidney meridian. When moxa is burned, its special useful ingredients for the human body will come into play, and with the heat it can penetrate well into the deeper meridians of the skin and muscles, and at the same time, the wavelengths and frequencies produced by its burning are like the infrared rays we usually use, and under its action, the freezing and blockage of blood caused by cold will be melted away, so that the qi and blood can run smoothly. The warming paste is also used to warm the uterus through the absorption of acupuncture points to achieve the purpose of removing the cold in the uterus. When the uterus is as warm as spring, the fertilized egg can be laid and grow smoothly.
