Barley tea can return to the breast in a few days can not be generalized, mostly related to the amount of barley tea and personal constitution. Barley tea is made from barley processed by special roasting treatment, which has the effect of removing food and healing distension, eliminating accumulation of food and regulating Qi, and is also one of the common means used by Chinese medicine to help return breast milk. The specific time of milk return and the effect of milk return varies from person to person and from quantity to quantity. A small amount may not return milk, while most women will return milk within 7 days after moderate consumption, but there are a few women who have poor or ineffective results due to individual differences. In addition, pregnant women can also gradually reduce the number of times their baby takes breast milk and shorten the duration of each feeding. When the baby’s sucking stimulation is reduced, the amount of milk secretion will also decrease. Also, attention should be paid to the need for a light diet, less soup, avoiding or eating less protein-rich food, etc., which also helps to return breast milk.
