Fennel for What?!

Here we go again. Another day, same old question — or, at least, same type of question. Mothers [somewhere] are using [something] for [some breastfeeding problem — almost always this is “to increase their milk supply”]. This latest time, the question is about using fennel to increase milk supply. When I get these questions, it’s generally from a nurse I know, a lactation consultant, someone in one of my lactation courses, or someone for whom I’ve provided consulting services reaching out to me and asking: What do I think about it?

Quite honestly, almost always, my first response is “Oh for pity’s sake!” I am about up to “here” with all of these “experts” who talk about evidence-based practices in one breath, and then turn around and suggest some trendy new supplement in the next.

Vegetables for increased milk supply?

So now we come to question about using fennel to increase milk supply. Most of us know fennel as a vegetable we’ll find in the crisper drawer of our fridge, or at the local grocery market. Although it looks like a strange hybrid of celery and dill, fennel is most well-known for its anise-like, licorice-like flavor. The person who asked me about it wasn’t asking about the raw vegetable, though, but rather the use of an essential oil derived from it. What do I think about it?

Here’s what:

  • First, I don’t know of a scrap or research that even addresses this, much less anything showing its effectiveness.
  • Second, the IBLCE has made it very clear that herbals, when used in this way, are NOT something that the IBCLC can prescribe, recommend, suggest, or anything else. If the client mentions it, the IBCLC’s job is to point the mother to information, but not to “advise.” (IBCLCs that make a big deal about it are—and, as I see it, should not be—“suggesting” its use, especially if they deal in the oils on the side. Although I am not an ethicist, I feel that the ethics are questionable.)
  • Third, the Academy of Breastfeeding Medicine couldn’t have been much clearer in their galactagogues protocol, which basically says, in general, about products said to increase milk supply: the risks outweigh the benefits.

Looking for a magic fix

Everyone seems to want some magic pill, some silver bullet, using some kind of herb, drinking beer, or even fennel to increase milk supply, or relieve her postpartum worry. Rather than rely on the known principles of abundant milk-making (supply and demand), they want something to take, a cure-all, a fixative.

I’m hesitant to come out and decree ”Don’t use any of this stuff.” Botanical medicines have been used for thousands of years, and there may be some benefit to the use of such agents. However, there may not be. We don’t know.

No substitute for emptying breasts

But what we do know is that there is nothing that substitutes for frequent, complete emptying of the breast. For the mother to have enough milk, at least two conditions must be met:

Rather than reach for their essential oils, mothers concerned about their milk supply should reach for their babies — at the earliest signs of hunger. “Remove to refill” is my mantra for anyone worried they’re not producing enough milk.

    Amen, Marie. Short, sweet and to the point. In the absence of pathophysiology, Want More Milk, Empty More Often.
