The placenta is technically classified as medical waste the moment it detaches from the uterine wall, and most hospitals incinerate it along with other biological tissue. But that classification obscures a growing reality: placentas are the raw material for pharmaceutical products, surgical grafts, cosmetic ingredients, and an expanding frontier of stem cell research. Depending on what happens to it after delivery, a single placenta can be worth nothing, a few hundred dollars to an encapsulation service, or be the starting point for medical products that sell for thousands. The question of its “worth” depends entirely on who wants it and what they plan to do with it.
What Happens to Most Placentas
In standard hospital practice, the placenta is examined briefly by medical staff for abnormalities, then disposed of as pathological waste. You typically have no automatic right to take it home, and policies vary by hospital and jurisdiction. Some facilities require you to sign release forms in advance, and a few charge administrative fees for releasing biological tissue. In Western medical settings, the default assumption is that the placenta served its purpose during pregnancy and has no further use to the mother.
That assumption has been challenged from two very different directions. One is a revival of traditional and alternative practices around consuming or ritualizing the placenta. The other is a fast-growing biomedical industry that processes donated placental tissue into grafts, extracts, and research materials. Both camps see something valuable in what hospitals routinely throw away.
The Encapsulation Market
Placenta encapsulation services, where a specialist dehydrates, grinds, and packages your placenta into supplement capsules, typically charge between $200 and $400 in the United States. The practice has grown steadily over the past two decades, driven by claims that consuming your own placenta can ease postpartum depression, boost energy, improve milk supply, and restore hormonal balance. In surveys, a majority of women who tried it reported perceived positive effects and said they would do it again after future births.1PubMed. Human maternal placentophagy: a survey of self-reported motivations and experiences associated with placenta consumption
The trouble is that controlled research has not confirmed any of those benefits. A review in the American Journal of Obstetrics and Gynecology found no scientific evidence of clinical benefit from human placentophagy and reported that the encapsulation process does not retain hormones or nutrients in amounts that could plausibly help the mother postpartum.2PubMed. Human placentophagy: a review A broader analysis of the evidence concluded that the purported effects of hormonal balance, prevention of postpartum depression, and enhanced lactation have not been demonstrated, and most reported benefits appear to be placebo-driven.3PubMed Central. Placentophagia in Tribal and Modern Societies: Navigating the Thin Line Between Risk and Benefit
The risks, on the other hand, are not theoretical. The CDC issued a warning after a newborn developed recurrent group B Streptococcus sepsis traced to contaminated placenta capsules the mother had been taking. The agency recommended avoiding placenta capsules because the encapsulation process does not reliably eliminate infectious pathogens.2PubMed. Human placentophagy: a review Additional concerns include exposure to heavy metals accumulated in placental tissue and potential endocrine disruption from concentrated hormones.3PubMed Central. Placentophagia in Tribal and Modern Societies: Navigating the Thin Line Between Risk and Benefit Neither the CDC nor the American College of Obstetricians and Gynecologists recommends placentophagy. So in terms of personal health value, the evidence suggests your placenta is worth more as a conversation topic than as a supplement.
Amniotic Membrane Grafts in Surgery
The most established and lucrative commercial use of placental tissue is not the placenta itself but the amniotic membrane, the thin inner lining of the sac that surrounds the fetus. Processed amniotic membrane is used in ophthalmology, wound care, orthopedics, and reconstructive surgery. It is genuinely valuable medical material, and this is where the economics start to get interesting.
In eye surgery, amniotic membrane transplants serve as a substitute for damaged corneal or conjunctival tissue. The membrane has anti-inflammatory and anti-scarring properties and contains growth factors that promote healing on the surface of the eye. It has proven effective for treating acute chemical burns, persistent corneal defects, and diseases that cause conjunctival scarring.4PubMed Central. Amniotic membrane transplantation in the human eye It can also be used after the surgical removal of conjunctival tumors, where preserving the remaining tissue is critical.5Scientific Reports. Amniotic membrane application in surgical treatment of conjunctival tumors
In burn care, amniotic membrane dressings have been shown to speed wound healing at skin graft donor sites. One study found that healing time was roughly three and a half days shorter when amniotic membrane was used compared to standard dressings, with the added benefit of fewer painful dressing changes for the patient.6PubMed Central. Evaluation of Amniotic Membrane Effectiveness in Skin Graft Donor Site Dressing in Burn Patients
Companies that process and distribute amniotic tissue products operate in a multibillion-dollar regenerative medicine market. A single amniotic membrane graft can retail for hundreds to several thousand dollars depending on its size, processing method, and clinical application. Mothers who donate their placentas to tissue banks after cesarean sections (the preferred collection method, since it avoids vaginal contamination) typically receive nothing for the donation itself. The value is captured downstream, by the processing companies and distributors who turn raw tissue into a sterile, shelf-stable medical product.
Pharmaceutical Products Made from Placenta
In Japan and parts of East Asia, placental extract has an established pharmaceutical identity. Laennec, a human placental extract, was first approved by Japan’s Ministry of Health, Labour and Welfare for treating cirrhosis of the liver, and its approved indications later expanded to include improvement of liver function in chronic liver disease.7Frontiers in Pharmacology. Biological effects of human placental extracts – variations in manufacturing methods and compositions It is also used off-label for menopausal symptoms and fatigue, and the product is widely available in Japanese clinics.
The biological rationale is that placental extract contains a cocktail of biologically active substances with antioxidant, anti-inflammatory, and immunomodulatory properties.8PubMed Central. Protective Effect and Mechanism of Placenta Extract on Liver Animal studies have shown that human placental extract can reduce liver fibrosis, promote liver regeneration, and modulate inflammatory responses in rats with chemically induced liver damage.9PubMed. Placenta extract promote liver regeneration in CCl4-injured liver rat model These results are promising but remain largely preclinical, and placental extract products have not gained comparable regulatory approval in North America or Europe.
Animal-source placental products also circulate in the supplement and wellness market. Sheep placenta extract, for instance, is sold widely in Australia, New Zealand, and parts of Asia as an anti-aging supplement. Research on mouse models has shown it can improve antioxidant function and shift gut microbiota composition in ways associated with reduced aging markers.10Frontiers in Pharmacology. Effect of sheep placenta extract on D-galactose-induced aging mouse Whether these animal findings translate to meaningful anti-aging effects in humans remains unproven, but the products sell briskly regardless.
Placenta in Cosmetics and Skincare
Placental extract has been an ingredient in high-end skincare for decades, particularly in Japanese and Korean beauty markets. Products containing horse, sheep, or pig placental extract are marketed for anti-wrinkle and skin-rejuvenation effects. One single-blind comparative study found that a cream containing horse placental extract reduced both wrinkle depth and the number of wrinkles in the treated area around the eyes compared to the untreated side.11PubMed Central. Evaluating the Impact of a Cream Containing Horse Placental Extract on Eye Corner Wrinkles in Healthy Women: Single-Blind Comparative Study That is a single small study, and the anti-aging skincare industry has a long history of overstating modest results. Still, the cosmetic use of placental extracts represents another slice of the organ’s commercial footprint.
Human placental extract in cosmetics raises additional regulatory and ethical questions that animal-sourced versions sidestep. Most commercial skincare products use animal placenta specifically to avoid those complications, and the industry labels are not always transparent about the source species.
Stem Cells and Regenerative Medicine Research
The placenta is a rich source of mesenchymal stem cells, which can be isolated from the amniotic membrane, the chorion, or the umbilical cord tissue. These cells can differentiate into a wide variety of tissue types, including bone, fat, muscle, liver, heart, pancreatic, lung, and nerve cells.12PubMed. Placental stem cells That versatility makes the placenta a potential goldmine for regenerative medicine, and a growing number of clinical and preclinical studies are investigating whether placenta-derived cells can be used therapeutically.
One recent study demonstrated that human placenta-derived mesenchymal stem cells can stimulate nerve cell regeneration, promoting axon growth and restoring neuronal activity in retinal ganglion cells. The cells were effective under both normal and low-oxygen conditions, with slightly better performance under low oxygen.13Frontiers in Cell and Developmental Biology. Human placenta-derived mesenchymal stem cells stimulate neuronal regeneration by promoting axon growth and restoring neuronal activity Research like this is still in early stages, but it illustrates why biotech companies are willing to invest in placental tissue collection and banking.
This research value is harder to put a dollar figure on than a surgical graft or a cosmetic ingredient. But for the biotech companies and academic labs working in this space, access to fresh, properly collected placental tissue is essential. Several commercial tissue banks now recruit expectant mothers to donate placentas after planned cesarean deliveries, and the resulting cell lines and tissue products feed a pipeline that stretches from basic science through drug development.
Diagnostic Value During and After Pregnancy
Beyond its commercial afterlife, the placenta has a less obvious but medically significant form of value: as a diagnostic tool during pregnancy itself. The placenta continuously releases tiny membrane-bound particles called extracellular vesicles into the mother’s bloodstream. These vesicles carry proteins, lipids, and genetic material from the placenta’s surface, effectively broadcasting information about placental health to the maternal circulation.14PubMed Central. Syncytiotrophoblast extracellular vesicles – Circulating biopsies reflecting placental health
Researchers are developing these vesicles into what amounts to a liquid biopsy for pregnancy complications. Conditions like preeclampsia, fetal growth restriction, and gestational diabetes show altered patterns of placenta-derived vesicles in maternal blood, raising the possibility of early detection through a simple blood draw.15PubMed Central. Placenta-Derived Extracellular Vesicles in Pregnancy Complications and Prospects on a Liquid Biopsy for Hemoglobin Bart’s Disease Emerging work also suggests these vesicles play a direct role in fetal brain development, which could open up diagnostic windows for neurodevelopmental concerns as well.16PubMed Central. Placenta-derived extracellular vesicles in fetal health: emerging insights into brain development and environmental interactions
Meanwhile, circulating biomarkers like placental growth factor and soluble fms-like tyrosine kinase 1 are already being investigated as screening tools for placental dysfunction and fetal growth restriction, though their clinical utility is still being established.17Clinical Science. Circulating biomarkers associated with placental dysfunction and their utility for predicting fetal growth restriction The diagnostic value here is not something you can sell on a marketplace, but for the companies developing these screening tests, the intellectual property around placental biomarkers is worth a great deal.
The “Placenta-on-a-Chip” and Drug Screening
One of the more futuristic applications is the development of microengineered models that replicate the placental barrier on a chip. These tiny devices recreate the interface where maternal and fetal blood come close together but do not mix, allowing researchers to study how drugs cross from mother to fetus. Using the gestational diabetes drug glyburide as a test compound, one research team showed that their placenta-on-a-chip could reproduce the active transport mechanisms that limit fetal drug exposure in real placentas.18PubMed Central. Placental drug transport-on-a-chip: a microengineered in vitro model of transporter-mediated drug efflux in the human placental barrier
The significance is practical: pregnant women are largely excluded from drug trials for safety reasons, leaving clinicians to guess about fetal exposure when prescribing medications during pregnancy. A reliable screening platform could change that. The commercial potential of a validated placenta-on-a-chip system, licensed to pharmaceutical companies for prenatal drug safety testing, would be substantial. It would not need actual placental tissue at scale, but developing it requires deep understanding of placental biology and access to tissue samples for validation.
Cultural Worth and the Question of Ownership
Not all placental value is commercial. For many indigenous communities worldwide, the placenta carries spiritual or ancestral significance. An integrative review of global indigenous practices found that while Western medicine treats the placenta as disposable waste, indigenous groups commonly observe rituals or ceremonies before disposing of it, because it holds sacred importance.19PubMed Central. The Disposal of Placenta among Indigenous Groups Globally: An Integrative Literature Review Burial ceremonies, tree plantings, and formal return of the placenta to the family are common practices across Māori, Navajo, and many other cultures. For these communities, the relevant question is not what the placenta is worth but who it belongs to.
That ownership question gets thorny when the placenta enters commercial channels. Ethicists have noted that the commercialization of placental tissue, whether as pills, creams, biomaterials, or cell therapies, often proceeds without clear pathways for donor recognition or benefit-sharing.20PubMed Central. Ethical considerations for advancing research using organoid models derived from the placenta A mother who donates her placenta for tissue banking typically signs a consent form and receives nothing financially, while the downstream products generated from that tissue may be sold for thousands of dollars per unit. The gap between what the donor gives and what the industry earns is a live ethical concern, particularly as researchers begin developing trophoblast organoids and other lab-grown models from donated placental cells.21Human Reproduction Update. Ethical considerations for advancing research using organoid models derived from the placenta
What the Placenta Actually Does (And Why It Matters for Value)
The reason the placenta has so many potential commercial and research applications is that it does an extraordinary amount of biological work. During pregnancy, it functions as the fetus’s lungs, liver, gut, kidneys, and endocrine system all at once.22PubMed Central. The placenta: a multifaceted, transient organ It transfers oxygen and nutrients, secretes hormones that reshape maternal metabolism, and modulates the mother’s immune system to prevent rejection of the genetically foreign fetus.23PubMed Central. Role of placental nutrient sensing in developmental programming That functional complexity is what makes its tissue biologically rich enough to be useful in so many downstream applications.
This multitasking also drives rapid evolution. The placenta is one of the fastest-evolving organs in mammals, shaped by what researchers describe as an evolutionary arms race between mother and fetus over resource allocation.24PubMed Central. Evolutionary perspectives into placental biology and disease Placental proteins that mediate interactions between mother and offspring show strong signatures of positive selection, meaning they have been changing unusually quickly over evolutionary time.25PubMed Central. Maternal-fetal conflict: rapidly evolving proteins in the rodent placenta This evolutionary arms race has even left visible traces in placental structure: species with less invasive placentas show compensatory changes in the fetal villi, as if the fetal side has evolved workarounds to maintain nutrient transfer despite reduced access to maternal tissue.26PubMed Central. Convergently evolved placental villi show multiscale structural adaptations to differential placental invasiveness
The Placental Microbiome Debate
For years, a handful of DNA sequencing studies suggested that the placenta harbors its own resident microbial community, much like the gut. If true, this would have added another layer of value: the placental microbiome could be a target for probiotic therapies, a predictive marker for pregnancy outcomes, or a tool for understanding how babies first encounter bacteria. The idea got significant media attention.
It now appears to have been wrong. A large study published in Nature found no evidence for resident bacteria in the vast majority of placental samples, from both complicated and uncomplicated pregnancies. Nearly all microbial signals could be traced to contamination, either from bacteria picked up during labor and delivery or from DNA in the laboratory reagents used for testing.27Nature. Human placenta has no microbiome but can contain potential pathogens A subsequent critical review that re-analyzed published placental microbiota datasets reached the same conclusion: the detected microbiota likely represents background DNA contamination rather than a genuine placental community.28PubMed Central. Is there a placental microbiota? A critical review and re-analysis of published placental microbiota datasets
The placenta is not, however, immune to the environment. Microplastics have been detected in placental tissue, where they can act as physical irritants and as carriers for secondary pollutants including endocrine-disrupting compounds and heavy metals.29Sarvodaya International Journal of Medicine. Microplastics in the Perinatal Period: Emerging Evidence on Maternal Exposure, Placental Transfer, and Fetal Health Outcomes The presence of environmental contaminants in placental tissue is an active area of concern, and it also adds a cautionary note about the safety of consuming processed placenta: whatever the mother was exposed to during pregnancy, traces of it may be concentrated in the tissue.
