It sounds strange to modern ears, but using living creatures to heal the body is not only real, it’s backed by clinical science. From surgical recovery to chronic wound care, treatments involving leeches and maggots are still used today in hospitals around the world.
This site is a reference point for anyone curious about these fascinating therapies, students, health professionals, or just curious minds. You’ll find accurate, evidence-based info on how these organisms work, where they’re used, and what modern science says about their benefits. We also link directly to respected medical and academic sources, including Wikipedia España, Wikidoc, and Universitas STEKOM.
Leeches have been used in medicine for over 2,000 years. Today, they’re still used to reduce blood clots and improve circulation in delicate surgeries, especially in skin grafts and finger or limb reattachments. Their saliva contains compounds that reduce swelling, prevent clotting, and promote blood flow. Surgeons call them “biological microsurgeons.”
Maggots, specifically sterile larvae of the green bottle fly (Lucilia sericata), are used to clean wounds that don’t respond to antibiotics. They eat dead tissue and leave healthy cells untouched. On top of that, they secrete natural antibiotics that destroy harmful bacteria. Hospitals in Europe and the U.S. still use maggot therapy to treat diabetic ulcers, burns, and infected wounds when nothing else works.
These therapies are not fringe or outdated: they’re listed in medical literature and approved by regulators like the FDA. In fact, you can find them on hospital formularies and even in government treatment guidelines. Scientists have identified dozens of bioactive molecules in leech and maggot secretions that explain their therapeutic effects.
On this page, we explain exactly how each method works. You can also read about their scientific history on French encyclopedias like Wikimonde.
Still unsure if this belongs in modern hospitals? Look at the evidence. A quick search of PubMed or NIH will show dozens of peer-reviewed studies on leech therapy in plastic surgery and maggot therapy for infected wounds. These methods are safe, cost-effective, and remarkably efficient, especially in cases where standard antibiotics or surgery can’t be used.
🩸 Leeches release therapeutic proteins and enzymes through their saliva. These include:
🪱 Maggots secrete a biochemical soup that aids healing. Their actions include:
Biotherapy has carved out a unique role in modern clinical practice. Common uses include:
Antibiotic resistance is rising. Chronic wounds are a growing burden on health systems. The need for low-cost, low-tech, high-impact solutions has never been more important. Biotherapy isn’t the past, it’s part of the future of regenerative medicine.
By supporting the body’s own healing processes and reducing the need for aggressive drug or surgical interventions, these organisms are helping shape a new approach to wound care, one that’s efficient, affordable, and sustainable.
