Lemon Balm Levels and Effects while Breastfeeding

Summary of Use during Lactation

Lemon balm contains a lemon-scented essential oil containing citronellal, neral, and geranial monoterpenoid aldehydes; polyphenolic compounds (including rosmarinic acid); and monoterpene glycosides. Lemon balm has no specific lactation-related uses. No data exist on the excretion of any components of lemon balm into breastmilk or on the safety and efficacy of lemon balm in nursing mothers or infants. However, it has been safely and effectively used with other herbs in infants for the treatment of colic, diarrhea, and other conditions,[1][2] so the smaller amounts expected (but not demonstrated) in breastmilk are likely not to be harmful with usual maternal doses. Lemon balm is "generally recognized as safe" (GRAS) as a food flavoring by the U.S. Food and Drug Administration. As a drug, it is generally well tolerated in adults with nausea, vomiting, abdominal pain, dizziness, and wheezing reported occasionally.

Dietary supplements do not require extensive pre-marketing approval from the U.S. Food and Drug Administration. Manufacturers are responsible to ensure the safety, but do not need to prove the safety and effectiveness of dietary supplements before they are marketed. Dietary supplements may contain multiple ingredients, and differences are often found between labeled and actual ingredients or their amounts. A manufacturer may contract with an independent organization to verify the quality of a product or its ingredients, but that does not certify the safety or effectiveness of a product. Because of the above issues, clinical testing results on one product may not be applicable to other products. More detailed information about dietary supplements is available elsewhere on the LactMed Web site.

Effects on Lactation and Breastmilk

A randomized trial assigned mothers of preterm infants to receive either a purported herbal galactogogue tea twice daily, a fruit tea twice daily or nothing. The galactogogue tea contained stinging nettle, lemon balm, caraway, anise, fennel, goat's rue, and lemon grass. All received similar breastfeeding advice from the same nurse and two groups were told that the tea would increase milk production, but compliance with the study teas was not assessed. The study was not blinded, and not analyzed on an intent-to-treat basis. Mother used breast pumps to extract and measure their milk output on day 1 and day 7 of the study. Although the volume of extracted milk was greater in the galactogogue tea group, there was no difference in infant weight gain nor in maternal serum prolactin between the groups at 7 days.[3]
