I don't follow why the effect on smooth muscle would affect milk
supply. I suppose it could possibly diminsh milk ejection, but the
mother could overcome that with breast compression. Fenugreek and
blessed thistle, 2 capsules four times a day, could increase her milk
supply. And supplements should be given *at the breast* with a
nursing supplement.
For info on compression and lactation aid as well as other things, see
