Fenugreek is helpful in promoting lactation in women.
Fenugreek is an herb that has been used for years by women wanting to stimulate lactation...but there are no clinical trials testing its efficacy or safety in mother or infant.
Some women have trouble producing breast milk on their own. This may be due to prematurity of the infant, illness of the mother or child, etc.
There are several anecdotal reports of the successful use of fenugreek for lactation.
