A galactagogue is a substance that promotes or increases milk production in breastfeeding mothers. These can be found in various forms, including foods, herbs, and medications. Common natural galactagogues include fenugreek, blessed thistle, and oatmeal, which are believed to help enhance lactation. While many women seek galactagogues to support breastfeeding, it's essential to consult a healthcare professional before using them. The effectiveness of these substances can vary from person to person, and some may have side effects or interact with other medications. Proper nutrition and hydration are also crucial for maintaining milk supply.
