Just a warning on cabbage leaves, if you are allergic to sulphates, you can't use them. My daughter cut cold turkey and the only thing that helped was a super-tight sports bra. ALTHOUGH-- I would check with your lactation consultant b/c of your mastitis (ouch, by the way) I don't know that that is a good choice for you. There are also herbs that help dry you up as well-- sage being one of them..... Good luck and I am so glad you were able to nurse for so long!

To use dried sage (Salvia officinalis) for reducing milk supply, take 1/4 teaspoon of sage 3x per day for 1-3 days. You can mix the sage in vegetable juice (for example, V-8), but it won't mix well into other juices. You can also mix it into other foods. If you don't like the taste of sage, try putting it into a tiny piece of sandwich and swallowing it whole - peanut butter or something else a bit sticky seems to work best for holding the sage in place. Tear off the corner of the sandwich containing the sage (it should be a very small section) and swallow it without chewing (that's why you need a very small section).
To use sage tea for decreasing milk supply, infuse 1 tablespoon of dried sage in 1 cup of boiling water (or 20g dried sage in 50 ml boiling water). Steep for 5-15 minutes. Drink 1 cup, 2 - 6 times per day.
You can use a tincture of sage instead: 30-60 drops of tincture, 3-6 times a day.
