Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Peppermint oil has traditionally been used to help reduce or "dry up" breast milk supply, particularly among women who are weaning or experiencing oversupply. The rationale stems largely from anecdotal reports and traditional practices rather than robust scientific studies. Some believe that topical application of peppermint oil to the breasts can reduce milk production, potentially due to the menthol content and its possible effects on lactation. A limited number of small studies and case reports suggest that peppermint (Mentha piperita) and other menthol-containing substances might decrease milk supply, but comprehensive clinical trials are lacking. Most of the evidence is derived from historical use and individual experiences rather than systematic research.

Healthcare providers sometimes caution breastfeeding mothers against ingesting large amounts of peppermint oil or using it topically on the breasts if they wish to maintain their milk supply, reflecting an acknowledgment of these traditional beliefs. However, the safety and efficacy of peppermint oil for this purpose have not been systematically established or validated by modern science. Women considering the use of peppermint oil to manage breast milk should consult with a healthcare provider to discuss potential risks and benefits, as well as alternative evidence-based methods for reducing milk supply.
