chained_bear I'll throw another usage out there:
"Galactagogues: These are substances that increase milk supply. Chemical galactogogues (found in prescription medications, such as domperidone) can increase prolactin levels (and milk supply) by blocking dopamine. Many people have had success with these drugs, although they are not effective in all situations, and may have side effects. Fennel, oatmeal, blessed thistle, and fenugreek are also used...."

palooka Wow, what a word! I thought it might refer to a demagogue on a galactic scale. Wikipedia defines it thus: "A galactagogue is a substance, typically a herb, that increases lactation. The most commonly used herbal galactagogues are fenugreek, blessed thistle, and alfalfa; others include anise, astragalus root, burdock, nettle, fennel, and vervain." Sep 21, 2007
