Mallow, Marsh (Althaea officinalis) root contains polysaccharide mucilage composed L-rhamnose, D-galactose, D-galacturonic acid, and D-glucuronic acid. Topical Mallow, Marsh preparations have been advocated for treating sore, cracked nipples[1] and breast pain.[2] Orally, Mallow, Marsh is a purported galactogogue,[3] and is included in some proprietary mixtures promoted to increase milk supply; however, no scientifically valid clinical trials support this use. Galactogogues should never replace evaluation and counseling on modifiable factors that affect milk production.[4] No data exist on the excretion of any components of Mallow, Marsh into breastmilk or on the safety and efficacy of Mallow, Marsh in nursing mothers or infants. Mallow, Marsh is generally well tolerated in adults, with allergic reactions reported rarely. Mallow, Marsh is "generally recognized as safe" (GRAS) in amounts found in foods by the U.S. Food and Drug Administration. Although no data exist on the safety of Mallow, Marsh root during breastfeeding, it is unlikely to be harmful to the breastfed infant. 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 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 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.

A small manufacturer-sponsored, double-blind, randomized study compared Mother's Milk tea (Traditional Medicinals, Sebastopol, CA) to lemon verbena tea in exclusively breastfeeding mothers with milk insufficiency. Each Mother's Milk tea bag contained an unspecified amount of Mallow, Marsh root as well as several other herbs. Mothers were instructed to drink 3 to 5 cups of tea daily. No differences were seen between groups in infant digestive, respiratory, dermatological, and other maternal-reported adverse events. No differences were seen in the growth parameters of the breastfed infants between the two groups.[5]
