The specific method of returning milk is relatively simple, which is to crack the mangosteen into a gauze bag and put it on the breast, which will reduce the local swelling and pain of the breast, but will not help to reduce the secretion of milk. If you want to return milk, it is also recommended to eat fried malt, such as two or two fried malt in water, as tea several times a day also has the effect of returning milk. If the effect is not good, you can also take oral supplement Jiale to give back milk. Do not drink too much soup, do not eat greasy food, and do not drink milk in the process of returning milk, as this will reduce the amount of milk secretion early, and finally reach the level of no secretion, then the milk is successfully withdrawn. Therefore, mannitol only plays a role in reducing the local swelling and pain of the breast in the process of returning milk.
