<<Perhaps we could all experiment -- put cold compresses & cabbage on
one engorged breast and applications of hot moist compresses on the
other breast and then double pump with a hospital grade electric pump
and see which seems to work the best.  It might be an interesting
experiment.>>

But yet another variable is the fact that most women do not produce
the same amount from each breast. Most of the women I have talked with
as a fellow pumping mother have a 'good' breast and a low producer.
Personally, I was able to get twice as much milk from the left than
the right. So if the cold was used on my left and warmth on my right,
how would  I know which actually worked better? Because  I got more
milk from the left then cold is better?
Just another thing to take into consideration. And this may partially
discount some of the other studies that use cabbage vs. ice or cold
cabbage vs. warm cabbage if there were no controls within the same
mom.
