Is Betony Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Betony? Is Betony safe for nursing mother and child? Does Betony extracts into breast milk? Does Betony has any long term or short term side effects on infants? Can Betony influence milk supply or can Betony decrease milk supply in lactating mothers?

Betony (Stachys sp.) is the name given to a group of plants from the genus Stachys that contain tannins and flavonoid glycosides. It has been used as a nerve tonic to treat anxiety and headaches, an astringent to treat diarrhea, and as a gargle for mouth and throat irritations. Betony is a purported galactogogue; however, no scientifically valid clinical trials support this use. Galactogogues should never replace evaluation and counseling on modifiable factors that affect milk production.[1] No data exist on the excretion of any components of betony into breastmilk. Because of a general lack of safety data, betony should be avoided during breastfeeding. 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.

Older studies performed in Eastern Europe claim that betony extract can increase milk supply and the protein content of breastmilk.[2][3][4] No modern, well-controlled studies were found as of the revision date.
