reduce your milk supply.
I did a quick google on anti galactagogue: here's a quote from this site:
http://www.iaac.ca/content/breastfeeding-adopted-child-0
Avoid the following anti-galactagogues, as they will decrease your milk supply if taken in large quantities:
Antihistamines
Decongestants
High-estrogen contraceptives (basically estrogen will decrease milk supply)
Parsley
Herb Robert
Lemon Balm
Oregano
Peppermint
Periwinkle Herb
Sage
Sorrell
Spearmint

For a blocked duct, try to orient baby's chin on the spot (if you can nurse lying down, you can get creative about positioning the babe or try different holds like the foot ball hold--I don't know where your soreness is.
BUT do watch it very closely, as soon as you start feeling sick, it's become infected and it's now mastitis and unless you can have baby nurse and drain the breast
really well, you'll need antibiotics, don't go longer than a day in this state.
OK, if it's still at the blocked duct stage, have your baby nurse on that side first and as baby nurses on that side, massage that spot. If baby wants to nurse on the other side, that is fine but do switch back to the sore breast as a last effort to drain it more.
If it does develop into mastitis, remember that the infection is not inside the milk duct but around it so it's very safe fr baby to nurse on that side and in fact, very necessary for you since emptying that side as best as you can will help.
BTW cabbage leaves only relieves engorgement.
as far as I know, blocked duct treatment is: empty breast as much as you can while massaging the spot, orient baby's chin on that spot (so, if blocked duct is on side near your arm, the foot ball hold would be best--the chin side tends to get emptied/has strongest suck--i read that somewhere when I had blocked duct problems and the other advice I got was to go bra-less, that sometimes it's the pressure causing the problem)
If you do pump (god how I hated to pump), be sure to also massage the spot as that side gets pumped. The massaging is to encourage emptying as much as possible.
The good news is that the blood flow to your chest during the nursing months is really great so healing happens quickly. (you'll see this if you have latch problems and are using lanolin ointment)
Don't feel badly if you do develop mastitis, it's
very common and often unavoidable.
I still remember the flush of the fever-like feeling I got when the blocked duct I had got worse--and this was some 9 years ago, it was that memorable and dramatic. I also felt let down by my body, once again, because nursing was so darn hard and there it goes throwing me another thing to deal with; it wasn't enough to have supply issues, latch issues AND a baby who needed to nurse around the freakin' clock, every 1-2 hrs. Oh those awesome yet overwhelming first 3 months!
keep us posted and sorry you are dealing with this.
