Recently, we have seen several women with breast milk blockage, all of whom had symptoms of breast swelling and pain, and were unable to discharge their breast milk. When asked about their medical history, they all had one thing in common: frequent consumption of chicken boiled in yellow wine or pig’s feet with ginger vinegar. Originally, the consumption of chicken boiled in yellow wine or pig’s feet and ginger vinegar after delivery is the custom of mothers in the Guangdong area, but according to my analysis, improper tonic, but may lead to breast milk, mammary gland blockage, and even cause mastitis. First, today’s big city women, most of the living conditions are better, prenatal nutrition is more adequate, coupled with the development of delivery technology, very few women in labor and delivery of women in the old days of simple deficiency of qi and blood symptoms. On the contrary, due to the prenatal diet of many women, the spleen and stomach can not be transported in time, easy to produce phlegm and dampness. Postnatal over-supplementation can easily accumulate heat on the basis of phlegm-dampness. Breasts for the yangming stomach meridians, spleen and stomach heat, easy to lead to the meridians can not be, milk can not be discharged smoothly, blockage, swelling and pain and other symptoms. Secondly, Guangzhou has a humid climate, especially in spring and winter. In summer, it is both hot and humid. At this time, the human body corresponds to the time of day, easy to gather moisture. If excessive consumption of warm tonic, but easy to aggravate dampness and heat. Damp-heat in the spleen and stomach, the stomach meridian is blocked, and the milk cannot be discharged smoothly after it is produced, which will easily lead to milk blockage. If the milk continues to be produced, the dampness and heat intensify, and it is easy to accumulate heat into carbuncle, which will develop into breast carbuncle. Therefore, I suggest that the customs of menstruation need to keep pace with the times, postpartum tonic need to be based on maternal constitution, do not blindly tonic. Mothers should drink plenty of water, to keep the bowels clear, to help the body drain dampness and heat.
