Context: Breastfeeding initiation is an important event during the postpartum period. Despite the significance of exclusive breastfeeding in infant health, some common breast issues lead to the early cessation of breastfeeding. Therefore, various complementary medicine techniques are used to increase the length and quality of breastfeeding. Objectives: The current review study collected evidence on the impacts of complementary medicine on successful breastfeeding and breastfeeding-associated problems in the postpartum period. Data Sources: A systematic search was performed on PubMed, Embase, Web of Science, Scopus, and ScienceDirect databases and all randomized clinical trial, quasi-experimental, observational, and case-control studies published from 1999 to 2018. The quality of the selected papers was measured based on their adherence to the strengthening the reporting of observational studies in epidemiology (STROBE) checklist. After careful examinations, 18 papers were selected and reviewed. Results: According to the results of the current review, point massage was beneficial to prevent low milk supply postpartum. Oketani breast massage significantly increased total solids, lipids, and casein content, as well as the gross energy of breast milk and thus improved its overall quality. Reflexology enhanced breast milk supply. The Gua-Sha therapy, Oketani massage, and hollyhock leaf compress decreased the mean severity of breast engorgement. The six-step recanalization manual therapy (SSRMT) could be used as a safe and low-cost method to treat plugged milk ducts after delivery. Nipple fissures could be relieved by the use of Pistacia atlantica resin, silver impregnate medical cap, lanoline, menthol essence, and Ziziphus jujuba fruit. Conclusions: Supplementary medicine techniques are inexpensive and safe methods to resolve breastfeeding problems and empower mothers to perform successful breastfeeding. These methods can thus promote exclusive breastfeeding and decrease infant morbidity and morbidity. However, further details are needed in this area.
