One of the reasons this is not recommended for human use, is the FDA or USDA, whichever controls this, has different guidelines obviously for products used for humans vs animals. This includes the level of cleanliness used to process product, purity of product, etc.i.e. an animal product, since it is used in a barnyard etc, might be allowed to have a few dead bugs, hairs, etc per batch that obviously would not be allowed in a human pharmaceutical. Don't mean to gross anyone out, but since tomato sauce manufacturers for example are allowed to have a certain level of mold before the product is declared non-edible, I really wouldn't want to think about what's ok in vet products. So what I've told folks who ask about BB is just this: that it is a product designed specifically for animals, and not intended for internal use, and since one of the reasons we breastfeed is to provide our baby the best food, that we have some measure of quality control over, and the manufacturer dosen't recommend this for human use, then I obviously can't recommend it. Then I go into my song & dance about how we do heal sore nipples, correct positioning, etc, and there is a product that is the main ingredient in BB but in a highly purified form, etc. Kathe Catone, IBCLC, LLLL ([log in to unmask])
