A historical perspective on placenta extract
The use of placenta extract is not a recent phenomenon. Its roots can be traced back over 1,500 years in Traditional Chinese Medicine (TCM), where it was known as "zi he che". Historically, it was used to treat conditions such as infertility, impotence, and liver and kidney problems, believed to boost energy and vitality. In modern medicine, initial applications in the early 20th century involved using placental membranes for wound repair and skin grafting. Since the 1950s, particularly in Japan, placenta extracts have been incorporated into aesthetic and anti-aging treatments. Today, both animal-derived (e.g., porcine or sheep) and human placenta extracts are used in various forms, including oral supplements, topical creams, and injections.
The science behind the claims
Proponents point to the placenta's rich biological composition as the source of its potential benefits. The organ is a powerhouse of bioactive compounds, including hormones, cytokines, growth factors, vitamins, minerals, and amino acids. These components are believed to drive the therapeutic and aesthetic effects attributed to the extract. However, the scientific evidence supporting many of these claims, particularly for oral consumption (placentophagy), remains sparse and often conflicting.
Potential benefits for skin health and anti-aging
One of the most popular uses for placenta extract is in skincare and anti-aging. The extract contains epidermal growth factor (EGF) and fibroblast growth factor (FGF), which are known to stimulate cellular regeneration and promote the production of collagen and elastin. These proteins are essential for maintaining skin's elasticity, firmness, and overall youthful appearance.
- Improved Hydration: The presence of hyaluronic acid in the extract can help the skin retain moisture, leading to a plumper, more hydrated complexion.
- Reduced Fine Lines: By supporting collagen synthesis, placenta extract may help diminish the appearance of fine lines and wrinkles.
- Enhanced Brightness: Antioxidants like vitamins C and E help protect the skin from free radicals and environmental damage, contributing to a more radiant and even skin tone.
Several studies have explored these effects. For instance, a randomized, double-blind, placebo-controlled clinical study on porcine placenta extract showed significant improvements in skin hydration and wrinkles in participants. Topical applications, including serums and creams, are widely available, with some clinics offering more intensive treatments like placenta facials and injections.
Supporting wound healing
Placenta extract's regenerative properties extend to wound care. Its rich content of growth factors and other peptides can help accelerate healing by promoting cell proliferation and reducing inflammation. The use of placenta-derived products in wound management is a documented practice in modern medicine, especially for chronic and non-healing wounds. A case study demonstrated the effectiveness of a placental extract gel in improving the healing and cosmetic outcome of a skin graft donor site in a 12-year-old child.
Hormonal balance and postpartum wellness
In the context of postpartum recovery, the practice of placentophagy has gained attention, with some believing it helps with mood stabilization, energy levels, and milk production. Supporters suggest that ingesting placental hormones might help counteract the dramatic drop in hormone levels after childbirth. However, robust scientific evidence is lacking for these claims related to oral consumption. Injections of placental extract are sometimes used in a clinical setting to manage menopausal symptoms and hormonal irregularities.
Anti-inflammatory and antioxidant effects
The extract's immunomodulatory and antioxidant properties are another area of therapeutic interest. Oxidative stress and inflammation are linked to various diseases and the aging process. Studies on animal models have shown that placenta extract can increase antioxidant enzyme activity, suggesting a protective effect against oxidative damage.
Joint health and osteoarthritis
Emerging research suggests a potential role for placenta extract in treating osteoarthritis, a degenerative joint disease. Its anti-inflammatory and regenerative properties could help mitigate cartilage degradation and create a more favorable environment for tissue repair. Animal studies have shown promising results, with injections of placental extracts demonstrating reduced joint deformity and a protective effect on cartilage.
Potential risks and considerations
Despite the purported benefits, there are significant risks and considerations associated with using placenta extract. A major concern, particularly with oral consumption, is the lack of regulation and standardization in processing. Improperly handled placental tissue can harbor bacteria and viruses, potentially transmitting infections. The Centers for Disease Control and Prevention (CDC) has issued warnings regarding the consumption of placenta capsules following a case of newborn infection.
Aspect | Oral Consumption (Placentophagy) | Topical Applications (Creams, Serums) | Injections (Laennec, Placentrax) |
---|---|---|---|
Source | Typically human (individual's own) | Often animal (porcine, sheep) | Human, processed under strict conditions |
Processing | Encapsulation or raw consumption, with no uniform standards | Sterilized and purified extracts from reputable sources | Pharmaceutical-grade sterilization and virus inactivation |
Evidence | Largely anecdotal, minimal clinical evidence | Empirical evidence, some clinical studies showing benefits | More established in clinical settings, especially in Asia |
Risks | Potential for infectious disease transmission, heavy metal exposure | Allergic reactions, irritation | Injection site reactions, allergic symptoms, rare systemic effects |
For products and treatments derived from human placenta, such as injections used in clinical settings, strict safety protocols are followed, including donor screening and virus inactivation. However, allergic reactions and other adverse effects, though rare, have been reported.
Conclusion
Placenta extract, with its long history in traditional medicine, is now a subject of modern scientific inquiry, exploring its potential benefits in skincare, wound healing, and other areas. While some applications, particularly topical and injectable formats manufactured under controlled conditions, show promising results supported by preliminary research, many claims—especially those related to oral consumption—are not yet backed by rigorous clinical evidence. Consumers should approach products containing placenta extract with a critical eye, prioritizing items from reputable manufacturers that adhere to strict safety standards. Consulting a healthcare professional is always recommended before starting any new supplement or treatment, especially if considering more invasive options like injections or unproven practices like placentophagy. This ensures decisions are based on sound information and a clear understanding of the risks and benefits.
