Drinking boiled malt water can restore milk. Malt has the effect of strengthening the spleen, eliminating food and returning milk. If you intend to return milk, you can use mangosteen to apply to the breasts externally while drinking malt water, which has the effect of astringent and swelling. Returning breast milk is a gradual process and should not be rushed. First, you should gradually reduce the number of breastfeeding sessions to reduce milk production. After breastfeeding begins, you should stop breastfeeding and do not empty your breasts. When breast swelling and pain are obvious, you can discharge a small amount of milk to relieve the pain. You should eat a light diet and not eat greasy and soup-like foods. You should also wear a suitable bra and avoid squeezing the breast or holding heavy objects to prevent mastitis. The use of medication to restore breast milk with estrogen and bromocriptine is not recommended because of the risk of blood clots. Vitamin B6 can be taken to achieve the effect of returning breast milk. Although the dosage is relatively high, it is taken for a short period of time and has no significant side effects.
