The lactation process is an important period for both mother and infant. This process begins with hormones during pregnancy. The lactation process begins immediately after birth with milk production, and the mother is affected both physiologically and psychologically by this process. The mother can be positively affected by this process as well as adversely affected by enviromental factors. Breast problems are often the first problems faced by women during the lactation process. At the same time, the breastfeeding process can be interrupted, which can lead to adverse consequences to both mother and infant. The use of chemical medicines in the treatment of problems during breastfeeding can affect the quality of the breastmilk and harm the infant. In this context, non-chemical complementary medical practices during the lactation period can help support breastfeeding and resolve breast problems. Complementary medical practices within the framework of breastfeeding guidelines may be included in the maintenance practices of nurses working in this area. In this review, studies on the effects of complementary medicine on breastfeeding and breastfeeding problems during the lactation process were examined and the activities of complementary medicine and the role of nursing maintenance and support of breastfeeding were examined.
