When some folks I know started talking about having their babies' placentas made into pills so the mother could ingest them, I asked the obvious question - why would you want to do that?
Answers were passionate and certain, full of bare assertion and lacking all but the slightest actual justification:
"prevents post partum depression and helps with milk production!"
"give you back your energy too"
"all the hormones that your body needs...its like your own specialized concoction of vitamins and hormones that are made especially for you"
"I think that every mammal eats the placenta after birth... the placenta holds all the vitamins that the... body is depleted of during pregnancy, so it makes sense to put those back into the body after birth"
One person linked to a blog post that had this citation:
"181 out of 210 women who were given dried placenta to increase milk supply had positive results and saw an increase in their milk supply.
Placenta as a Lactagogon; Gynaecologia 138: 617-627, 1954"
Now, first let me say, if you would like to consume your baby's placenta on the off chance it will do you good, I suppose you should go for it. I don't see much harm. If it does nothing, you'll lose some money to a professional encapsulator. Of course safe handling is important, just like with raw beef or chicken or whatever. But really, whatever floats your boat.
I'll also grant that it's possible that placentophagy could have some benefits. It's not completely ridiculous, the way homeopathy is. It's at least feasible that recouping iron and hormones could be beneficial.
But here's my problem - this is at best a hypothesis. It's testable, but hasn't really been tested (as far as I can tell, that study didn't use a control group, and the sample is small to boot). It's a pretty big leap from "animals do this" and "it contains hormones" to "ingesting dried placenta prevents depression and low milk supply."
And why are people so eager to make that leap? Because it's "natural." You won't see this wide-eyed credulity when it comes to vaccines, for damn sure. People who avoid ingesting acetaminophen or corn syrup jump at the chance to chow down on placenta, because that's what sheep do. It just doesn't make sense to me. And I'm worried about the general mentality because it leads to distrust of science-based medicine and encourages faith in altmed woo.

Scene from an Acupuncturist's
Patient: So, I've never done this before. Can you tell me how this goes?
Acupuncturist: Well, first I clear an hour for your appointment. We spend a lot of time sitting and discussing your problems, your life, and what you're looking for in treatment. I try not to talk too much, but just to listen to you.
Then I have you get comfortable and completely relaxed in our treatment room. It is decorated in a serene theme, and has scented candles and soft, tranquil music. You lie down on our padded table and close your eyes.
In my practice, I focus on respecting you as a complete person. I don't treat you like a broken machine with one part that needs fixing; rather, I concentrate on supporting your total wellness, including mental and emotional health.
I provide caring, supportive human touch in a professional context that is all about you and what feels good for your body.
Oh, and I also stick needles in you.
Patient: Maybe we could just skip that last part?

Quick and Easy Guide to Spotting Altmed Bunk
Immersed in the world of breastfeeding and attachment parenting as I am, I am unfortunately bombarded with loads of alternative medicine hogwash. As I dutifully (and usually futilely) research and dissect the latest advice from someone's naturopath, or the information they got from their chiropractor, I have noticed certain signs that will cause my bullshit meter to bury the needle. What follows isn't a detailed discussion of why altmed practices are unscientific, or how to decide if a research study is reliable, or a treatise on the philosophy of science. It's just a quick and dirty list of features that anti-scientific quackery tends to share.
1. Most of the hits on Google are sites that promote or sell the product in question. Typical site names are phlebotinum.com, phlebotinum-advisory-group.net, drlaceyunderall.net, yournaturalhealth.com, and so on. Many strive to look like health information sites, but if they have only good things to say, and an easy link to purchase the product, you can bet it's just a commercial site shilling. If you get a high proportion of hits like Webmd, Mayo Clinic, National Institutes of Health, and maybe stuff like CNN or ABC stories, it has a much greater chance of being a real thing.
2. The remedy is promoted as a solution for vague and ubiquitous maladies. Usual suspects are fatigue, insomnia, body aches, headache, mood problems, low sex drive, weight gain, nausea, and constipation. Now these can be real symptoms of real problems. But when you see a product promoted as solving a long laundry list of these issues, it's time to raise an eyebrow. These symptoms are typically experienced by most people at least some of the time, especially in a culture plagued by poor diet, low rates of exercise, too little sleep, social isolation, and chronic stress.
Most of these symptoms are self-limiting, or can be alleviated by lifestyle change. But most people don't relish a prescription of "eat plenty of fruits and vegetables, exercise regularly, and get 8 hours of sleep a night." Lifestyle changes are difficult to initiate, harder to maintain, and are frankly a total drag. But give us a pill, a cream, or someone waving their hands over us once a week, and we perk right up - seems easy!
3. Self-diagnosis is encouraged. Whether it's checking off the laundry list of vague symptoms, or buying a test kit you can do at home, do-it-yourself is the name of the game for quacks. And if you did get tests at the doctor's office, they encourage re-interpretation. Doctor says your thyroid levels are fine? Well check your number against this web site's "more accurate" scale. Doctor says your hormone levels are healthy? Take a saliva test to find out more!
4. Remedy is promoted by an actress of fading fame. E.g., Jenny McCarthy and Suzanne Somers.
5. Proponents laud how natural the remedy is, and decry the toxins in the environment and/or conventional medicines. Arsenic is as natural as it gets - it's an element! Hemlock is a plant (make sure you get organically grown). Meanwhile insulin for diabetics is synthetic. Using "natural" as a synonym for "good" doesn't make sense. (Also look for the keyword "allopathic" to describe conventional medicine.)
6. Relies on testimonials, anecdotal evidence, appeals to authority. Approaches that work don't need this type of weak support, because they have strong scientific evidence - the kind that attempts to sweep away all the human foibles that can prevent us from seeing what's really happening, and determine if an intervention has a real effect.
7. Provides citations as though they refer to peer-reviewed scientific journals, but the cited material is actually a book, presentation, or web site of an individual proponent of the remedy. It doesn't matter how many letters are after your name - just because you say it doesn't make it reliable. Publication in a respected journal indicates your claims have been examined and probed for mistakes and found robust. Publication on a website means you successfully Googled GoDaddy.
8. Users respond to skeptical inquiry and questioning of the evidence by saying, "I KNOW this works - it worked for me." When the people trying to sell you on something have no clue about placebo effect, confirmation bias, coincidence, self-limiting conditions, and general methods for removing human perceptual bias, you can dismiss pretty much everything they say.
9. Praises or demonizes according to fad. Acai berries are magically delicious, butVDTs, power lines, electrical transformers, cell phones, Wifi is evil.
10. Invokes the Pentaverate. Promoters wave away criticism as the result of wide-reaching conspiracies involving doctors, pharmaceutical companies, the CDC, and other entities.
11. The remedy is said to have no possible side effects or risks. Generally if something can have an effect, it can have a side effect. If it can change your body in some way, that change might turn out badly for you. Even such benign and universally prescribed practices as exercise and high fiber diets have risks and side effects.

Package-deal Skepticism
In the crunchy mothering world, I run into this odd phenomenon. Women get involved in some aspect of mothering that is counter-cultural: extended breastfeeding or natural childbirth for instance - practices that are actually supported by evidence or are merely matters of personal preference. By engaging in this "weird" behavior, they find themselves battling against social norms and doctors' expectations. They find support in a group of like-minded people, and get used to filtering, altering, or outright rejecting advice from uninitiated people, from mothers in law to pediatricians.
Now, it can be perfectly rational to take uninformed advice with a grain of salt. And sadly even experts can be terribly uninformed about, say, breastfeeding. Doctors don't get a lot of training in this area, and often even well-read laypeople will be more up to date on the research than medical professionals.
The problem is, many people seem built not to question everything, but to act more like they're choosing between competing clubs. So many women just seem to see it as a choice between boilerplate belief systems, rather than an investigation into the truth. Either you eat processed factory farmed foods, have an intervention-heavy birth in a hospital, feed your baby formula, vaccinate them, and keep them in a car seat or crib 24/7, OR you eat organic whole foods, have a homebirth, nurse your child until they decide to stop, skip vaccinations in favor of homeopathic remedies, and wear them and cosleep with them.
The choice to reject medical authorities on one subject (which may make sense) tends to lead to rejection of all scientific authority and adoption of crunchy-culture alternatives, even in cases like homeopathy, when it is completely stupid.
