Hi Crazy, well fenugreek is one of the herbs used in curry mixtures and my wife also puts it in other stuff but I can't say that is has done anything for her breast size over the years, try this for info http://www.foodreference.com/html/artfenugreek.html
Apparently it has been used to help with producing breast milk, but that's the only breast-related thing I could find about it! It does have a lot of other uses though:
