Is Astragalus Safe in Breastfeeding

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

Astragalus (Astragalus membranaceus) root contains numerous saponins and isoflavones. Astragalus is a purported galactogogue;[1] however, no scientifically valid clinical trials support this use. Galactogogues should never replace evaluation and counseling on modifiable factors that affect milk production.[2] No data exist on the excretion of any components of Astragalus into breastmilk or on the safety and efficacy of Astragalus in nursing mothers or infants. Astragalus is generally well tolerated, with mild gastrointestinal irritation and allergic reactions reported. 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.
