The phenomenon of returning to milk due to anger during lactation is due to qi stagnation and blood stasis, which affects the blood supply of breast tissue and leads to the decrease of milk secretion. In this case, you can take some Chinese patent medicines with the functions of soothing the liver, regulating qi, promoting blood circulation and removing blood stasis. It is generally recommended to take Chaihu Shugan Pill or Danzhi Xiaoyao Pill for conditioning. At the same time, we should pay attention to adjusting our emotions and keep a happy mood and a peaceful mind. It can be combined with hot compress or manual massage to improve the blood supply to the breast and improve milk secretion. You can also eat some foods with prolactin effect in moderation, such as peanut trotter soup, cuttlefish soup and so on.
