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.

A nonblinded, randomized trial of Althaea rosea nigra extracts leaf compresses in addition to warm compresses followed by cold compresses was compared to the warm and cold compresses alone in the treatment of breast engorgement. Nursing mothers completed the procedures on their own and rated their own levels of engorgement based on a standard checklist. Twenty women in each group completed the study. Although both groups had a lessening of their engorgement scores over the 6-day study period, the mothers who used the Althaea rosea nigra extracts compresses had a more rapid decrease in engorgement.[1]
