In my first article about the Colima people of west Mexico, I focused on their artwork depicting fattened dogs and the importance of dogs for both dietary and ritual purposes. In addition to their dog sculptures, the ancient Colima between 300 BCE and 500 CE are also known for their distinctive ceramic figurines depicting illness, physical deformities, and medical conditions.

ClaudeAI elaborates: “The Colima figurines are notable for their realistic portrayals of various physical conditions, including:

  • Obesity and other body types
  • Hunchbacks and spinal deformities
  • Dwarfism
  • Various skin conditions
  • Facial deformities and cleft palates
  • Individuals with missing limbs

Archaeologists have found significant concentrations of these figurines in burial sites and settlements throughout the Colima region, particularly in the shaft tomb tradition characteristic of western Mexican cultures. These figurines are often referred to as "medical models" or "diagnostic figurines" because of their apparent anatomical accuracy.

The purpose of these figurines remains somewhat debated among scholars. Some interpretations suggest they may have had ritual significance related to healing practices, while others propose they might represent ancestors or important community members who lived with these conditions. They might also have served educational purposes for healers within these communities.

The Colima figurines represent one of the most detailed ancient artistic traditions depicting human pathology and physical diversity in pre-Columbian Mesoamerica.”

However, despite an apparent knowledge of human pathology, archaeologists have been unable to identify with certainty stone tools that may have served medical purposes in a shaman or healer’s toolkit.

ClaudeAI said: “Archaeological evidence for specialized medical instruments in Colima settlements is limited compared to the abundant figurines depicting medical conditions. However, some artifacts have been discovered that might have had medical applications:

  1. Obsidian blades and cutting tools that could have been used for procedures like bloodletting, minor surgeries, or scarification
  2. Bone needles and awls that may have served for wound suturing or draining abscesses
  3. Ceramic vessels that potentially contained medicinal preparations
  4. Stone grinding tools that could have been used to prepare herbal remedies and medicines

The interpretation of these items as specifically medical is often contextual rather than definitive, as many tools served multiple purposes in ancient societies. Unlike some other Mesoamerican cultures where specialized medical instruments have been more clearly identified, the Colima evidence is more suggestive than conclusive.

What's particularly interesting is the contrast between the detailed and anatomically accurate figurines depicting illness and the relative scarcity of specialized medical implements. This suggests the Colima people had sophisticated observational knowledge of medical conditions, even if their treatment approaches may have relied more on botanical medicines, spiritual practices, or relatively simple tools that were also used for other purposes.”

I thought perhaps this may be the result of a lack of metalworking.  ChatGPT agreed to some extent:

“Yes, the lack of metalworking in the shaft tomb cultures of West Mexico (such as those of Colima, Nayarit, and Jalisco, c. 300 BCE–400 CE) would have significantly influenced the development of medical instruments. However, it may not have completely prevented medical procedures, as stone and obsidian tools could have served as effective substitutes [for some procedures.}”

Impact of No Metalworking on Medical Practices

  1. Surgical Limitations
    • Cultures with metal tools (such as those in Mesoamerica during the Postclassic period or Bronze Age Eurasia) could create finer, more durable, and reusable medical instruments.
    • The absence of metal scalpels, forceps, and needles in West Mexican shaft tomb cultures likely meant a reliance on sharpened obsidian, stone, or bone tools, which, while extremely sharp, are also brittle and require more careful handling.
  2. Alternative Cutting Tools
    • Obsidian blades: Known for their exceptional sharpness—finer than modern surgical steel—obsidian could have been used for lancing abscesses, bloodletting, or even rudimentary surgeries like trepanation (as seen in other Mesoamerican cultures).
    • Stone knives and scrapers: These could have been used in wound care, amputation, or other medical treatments but would lack the precision of metal scalpels.
  3. Evidence from Colima Figurines
    • Colima figurines display realistic depictions of human pathology, including hunchbacks, tumors, facial deformities, and possible representations of diseases like polio or clubfoot.
    • This suggests a high level of observational knowledge of human health and disease, but whether this knowledge translated into medical interventions remains unclear.
    • If surgery or medical treatment was practiced, the tools would have been perishable (wood, bone) or stone-based, which are harder to identify archaeologically.
  4. Ethnographic Comparisons
    • Later Mesoamerican cultures, like the Aztecs and Maya, had sophisticated medical knowledge using herbal remedies and obsidian scalpels for bloodletting and minor surgical procedures.
    • Some indigenous traditions survived into the colonial period, documenting practices such as cauterization and wound stitching using maguey thorns instead of metal needles—techniques that may have parallels in earlier shaft tomb cultures.

Conclusion

The lack of metalworking would have limited, but not entirely prevented, the development of medical instruments in shaft tomb cultures. The use of obsidian and stone tools could have supported certain medical interventions, but without metal, more delicate procedures (e.g., suturing, internal surgery) would have been difficult. The detailed pathological observations in Colima figurines suggest an awareness of illness and deformity, but without direct evidence of surgical tools, their medical interventions likely relied more on external treatments and possibly ritual healing.”

ChatGPT offered comparison of Colima possible medical practices with those of other non-metalworking cultures:

Comparison of Colima (Shaft Tomb Culture) with Other Non-Metalworking Cultures in Medical Instrument Development

Several cultures around the world developed medical practices without access to metal tools, relying on stone, bone, wood, and obsidian. Below is a comparison between the Colima shaft tomb culture and other non-metalworking societies with evidence of medical interventions.


1. Colima (West Mexico Shaft Tomb Culture, c. 300 BCE–400 CE)

Medical Evidence

  • Colima figurines depict a variety of human ailments, including hunchbacks, missing limbs, facial deformities, and possibly infectious diseases.
  • No definitive evidence of surgical tools, though obsidian and stone knives were common in West Mexico.
  • Possible use of herbal remedies, inferred from broader Mesoamerican traditions (e.g., the later Aztecs’ extensive herbal pharmacopoeia).
  • No confirmed trepanation cases, unlike other pre-Columbian cultures.

Challenges Due to Lack of Metal

  • Obsidian blades were available but brittle, limiting complex procedures.
  • No metal needles or clamps meant that wound stitching, cauterization, and internal surgery were difficult or impossible.

2. Chinchorro Culture (Chile & Peru, c. 7000–1500 BCE)

Medical Evidence

  • Practiced advanced mummification techniques thousands of years before Egypt.
  • Used stone tools to remove organs and preserve the body, implying knowledge of anatomy.
  • Some evidence of cranial modification but no confirmed surgery.

Comparison with Colima

  • More advanced mortuary practices, suggesting detailed anatomical knowledge.
  • Both cultures showed awareness of human pathology, but Chinchorro’s advanced mummification suggests greater hands-on intervention.
  • Like Colima, no metal tools, but flint and stone were used for body modifications.

3. Paracas Culture (Peru, c. 800 BCE–100 CE)

Medical Evidence

  • Trepanation (cranial surgery): Many Paracas skulls show evidence of drilling, with high survival rates, indicating post-surgical care.
  • Used obsidian and sharp stone tools for cutting.
  • Textiles were possibly used as bandages or for wound dressing.

Comparison with Colima

  • Paracas practiced surgery, while Colima did not (as far as we know).
  • Both had knowledge of human pathology, but Paracas had direct surgical interventions.
  • Obsidian and stone tools were used for medical purposes in both cultures, but Paracas used them for skull surgery, a practice absent in West Mexico.

4. Indigenous Australian Cultures (50,000 BCE–present, pre-metal age before European contact)

Medical Evidence

  • Use of sharp stone tools for minor surgeries, such as lancing boils and circumcision.
  • Bone and shell tools for dental work.
  • Cauterization and bloodletting were common healing practices.

Comparison with Colima

  • Both cultures relied on non-metal tools, but Australian cultures used burning and cauterization, while there is no evidence Colima did.
  • Australian cultures actively performed minor surgical procedures, whereas Colima’s medical interventions remain unclear.

5. Hawaiian & Polynesian Cultures (pre-contact period, before 18th century CE)

Medical Evidence

  • Shark-tooth scalpels and obsidian knives used for surgical procedures, including lancing abscesses, tattooing, and bone-setting.
  • Trepanation was rare but existed in some Polynesian cultures.
  • Coconut fibers were used for suturing wounds, a substitute for metal needles.

Comparison with Colima

  • Polynesians had a more developed surgical tradition, with documented wound treatment methods.
  • Use of sharp organic materials (shark teeth) was a parallel to Colima’s obsidian tools.
  • Polynesians had more documented external medical interventions, while Colima’s medical practices remain speculative.

Conclusions: Colima vs. Other Non-Metalworking Cultures

1. Medical Awareness

  • Colima figurines suggest highly detailed observations of human pathology, similar to Paracas and Chinchorro mortuary practices.
  • However, there is no direct evidence that Colima used this knowledge for surgery as Paracas did.

2. Surgical Tools

  • Colima, like Paracas and Polynesians, had obsidian blades, but the latter cultures used them for surgical interventions.
  • Colima’s lack of metal tools limited precision but did not necessarily prevent procedures like lancing infections or simple wound care.

3. Unique Characteristics

  • Paracas and Polynesians showed direct surgical applications, whereas Colima’s medical knowledge seems more observational than practiced.
  • Chinchorro’s mortuary practices were sophisticated, but Colima did not display similar post-mortem interventions beyond burial customs.

Final Thoughts

While Colima had detailed anatomical knowledge, its lack of metal tools likely prevented advanced medical procedures, unlike cultures such as Paracas and Polynesians, who developed stone-based surgical techniques. If Colima practiced medicine, it was likely herbal, external, or limited to wound care rather than surgical intervention.

Possible Medicinal Plants and Healing Rituals in Colima’s Shaft Tomb Culture

While no written records survive from the Colima (Shaft Tomb) culture, we can infer possible medicinal practices based on later Mesoamerican traditions, archaeological evidence, and the prevalence of healing-focused figurines in certain sites. Many of the plants used by the Aztecs, Maya, and contemporary Indigenous groups were likely available to the Colima people as well.


1. Medicinal Plants That May Have Been Used in Colima Healing Centers

🌿 Pain Relief & Anesthesia

  • Cacao (Theobroma cacao) – The Maya and Aztecs used cacao in medicinal drinks to treat fatigue and inflammation. It may have had a similar role in West Mexico.
  • Toloache (Datura stramonium) – A powerful hallucinogen and anesthetic used by Indigenous healers across Mesoamerica. Often used in shamanic rituals, it may have helped dull pain or induce trance states during healing ceremonies.
  • Wild Tobacco (Nicotiana rustica) – Used as a painkiller and antiseptic. Indigenous healers would chew or apply tobacco poultices to wounds or infected areas.

🌱 Antiseptics & Wound Treatment

  • Copal (Bursera spp.) – Resin burned in ceremonies but also applied to wounds as a natural antiseptic.
  • Aloe Vera (Aloe spp.) – Used for treating burns, wounds, and skin infections. Aloe grows naturally in Mexico and may have been part of Colima healing.
  • Agave (Agave spp.) – Agave sap was used to disinfect wounds, and its fibers were sometimes used as sutures.
  • Obsidian Dust (Volcanic Glass Fragments) – Obsidian knives are known, but fine obsidian powder was sometimes used in later Mesoamerican medicine as an antibacterial agent for wound dressing.

🍵 Digestive & Internal Ailments

  • Epazote (Dysphania ambrosioides) – Used widely in Mesoamerica for treating parasites and digestive issues.
  • Guava Leaves (Psidium guajava) – Known for their antibacterial properties, these leaves may have been chewed or brewed into teas for stomach issues.
  • Hoja Santa (Piper auritum) – A plant with both culinary and medicinal uses, known for treating coughs, fever, and respiratory infections.

2. Healing Rituals and Shamanic Practices

🔥 Sweat Lodges (Temazcal)

  • Sweat lodges (temazcales) were common in Mesoamerican cultures, and evidence of similar practices may exist in West Mexico.
  • Used for:
    • Detoxification and purification.
    • Treating respiratory illnesses.
    • Healing joint and muscle pain.
  • A shaman might use herbal steam infusions by throwing medicinal plants like epazote, sage, and eucalyptus onto heated stones.

🩸 Bloodletting & Cupping

  • While evidence of bloodletting in Colima is unclear, it was widespread in Mesoamerica as a way to balance health, release illness, or appease spirits.
  • Obsidian blades, sharp thorns, or stingray spines may have been used for small incisions in healing rituals.

👤 Healing Through Figurines & Effigies

  • Some Colima figurines may have been used as effigies in healing rituals—possibly as prayer objects or representations of sick individuals to absorb illness.
  • Similar to later Mesoamerican practices, a shaman might have:
    • Buried, burned, or offered the figurine to rid a person of disease.
    • Used it in divination rituals to determine the cause of an illness.

🌬️ Use of Hallucinogens in Shamanic Healing

  • Peyote (Lophophora williamsii) – Found in nearby regions, peyote was a sacred hallucinogen used in healing and vision quests. Shamans may have used it to diagnose illnesses or communicate with spirits.
  • Datura (Toloache) – As mentioned earlier, it was potent but dangerous, inducing trances for shamanic healing.

3. Did the Colima Have Surgical Practices?

  • No skeletal evidence confirms surgeries, trepanations, or bone-setting in Colima culture.
  • However, given their advanced anatomical knowledge (as seen in figurines), it’s possible they practiced non-invasive treatments like massage therapy, wound care, and herbal medicine.
  • Obsidian scalpels could have been used for minor surgical procedures, as seen in later Mesoamerican cultures.

Final Thoughts

  • The presence of healing centers, realistic disease depictions, and medicinal plant availability suggests the Colima had a structured healing system, likely led by shamans or specialized healers.
  • They may have relied on herbal medicine, ritual purification, and effigy-based healing, rather than invasive surgery.
  • The lack of metal tools may have limited the development of precise surgical techniques but did not prevent sophisticated healing traditions.
