Nine Needles of the Ling Shu: The Essence of Acupuncture
I. Origin of the Nine Needles

The Ling Shu (灵枢), one of the two major texts of the Huangdi Neijing (黄帝内经, Yellow Emperor’s Inner Classic), holds a pivotal place in classical Chinese medicine. While the Su Wen (素问), the first book of the Neijing, provides a theoretical foundation encompassing the principles of yin (阴) and yang (阳), the five elements, and the etiology of diseases, the Ling Shu delves into the practical methods of acupuncture. It is in the Ling Shu that we find detailed discussions on the meridian system, the application of needles, and various therapeutic techniques that form the backbone of traditional acupuncture.

A notable feature of the Ling Shu is its emphasis on the nine needles (九针, Jiu Zhen), which are integral tools in classical acupuncture. These needles represent a sophisticated system of treatment tailored to address various pathological conditions through specific techniques. The differentiation and appropriate use of these needles are crucial for effective clinical outcomes in Ling Shu based acupuncture.

It is important to recognize that the term “needle,” as used in the Ling Shu, encompasses a broad range of tools that can be categorized into three functional groups: non-insertive needles for rubbing and pressing, needles for draining body fluids such as bloodletting, draining pus, and reducing edema, and needles that resemble modern acupuncture needles. Each needle will be examined regarding its design, intended use, and appropriate techniques for treatment.

Understanding the nuances of these nine needles is essential for practitioners to ensure the correct application of acupuncture techniques. Using the wrong needle, such as employing the seventh needle (filiform needle) when addressing a condition at the blood level, can result in suboptimal outcomes or even exacerbate the patient’s condition. Therefore, a thorough comprehension of each needle’s specific role and application is imperative for the accurate and effective practice of acupuncture.

II. Historical Overview

The nine needles described in the Ling Shu represent a profound understanding of acupuncture tools and techniques in ancient China. The Ling Shu, often translated as the “Spiritual Pivot,” is a foundational text in Chinese medicine, attributed to the legendary Yellow Emperor, Huangdi. The text itself is a dialogue between the Huangdi and his minister Qi Bo, focusing on the practical applications of acupuncture.

In the opening chapter of the Ling Shu, Qi Bo’s first words emphasize the critical importance of understanding the nine needles. He explains to Huangdi that these needles are fundamental tools in acupuncture, essential for harmonizing the body’s qi and blood, restoring balance to the internal organs, and dispelling diseases. Qi Bo’s dialogue underscores that mastering the use of these nine needles is crucial for any practitioner aiming to achieve effective and precise therapeutic outcomes.

Origins and Historical Context

The Ling Shu, along with the Su Wen, forms the Huangdi Neijing, dating back to the Warring States period (475-221 BCE). The acupuncture needles and techniques described in the Ling Shu are very different and more diverse than the needles commonly used today. There was a greater emphasis on balance, harmony, and the flow of qi through meridians, rather than on the point actions and indications commonly used in modern TCM (Traditional Chinese Medicine).

Needle 1 The Arrowhead Needle

In the Ling Shu, Chapter 1 (九针十二原, Nine Needles and Twelve Source Points), it states: “The needles are instruments of the sages. By the use of the needles, the sages harmonized the qi and blood, restored balance to the internal organs, and dispelled diseases” (Ling Shu, Chapter 1). This passage highlights the importance placed on the needles as essential tools for maintaining health and treating ailments.

The Ling Shu describes nine specific types of needles for particular functions, demonstrating an advanced understanding of therapeutic interventions. The detailed descriptions of the nine needles provide a structured approach to acupuncture. Each needle has a specific technique and use associated with it. The needles are selected based on the location and type of disharmony or pathogenic influence affecting the patient.

The careful study of the nine needles underscore a fundamental tenet of acupuncture: the importance of selecting the appropriate tool and technique for each specific clinical scenario. The Ling Shu emphasizes that improper use of needles can lead to adverse outcomes, a caution that remains pertinent in modern practice. As stated in Chapter 1: “If one does not adhere to the principles of the nine needles, the disease may not be resolved and can even worsen” (Ling Shu, Chapter 1).

Needle 2 The Round Needle

The historical context provided by the Ling Shu offers invaluable insights into the development and refinement of acupuncture tools and techniques. Understanding the origins and evolution of the nine needles enhances our ability to apply these ancient practices effectively in contemporary clinical settings. Most modern acupuncturists have not been properly exposed to the nine needles and therefore are limited in their interventions. The Ling Shu offers a wide array of healing tools through the nine needles, and embracing them can enhance patient outcomes.

III. The Nine Needles: An Overview

The nine needles, as detailed in the Ling Shu, each have unique shapes, sizes, and intended uses. This classification allows for targeted treatments tailored to address various pathologies and patient conditions. Understanding the categorization and applications of these needles is essential for practitioners aiming to harness the full potential of traditional acupuncture techniques.

The nine needles, as detailed in the Ling Shu, each have unique shapes, sizes, and intended uses. This classification allows for targeted treatments tailored to address various pathologies and patient conditions. Understanding the categorization and applications of these needles is essential for practitioners aiming to harness the full potential of traditional acupuncture techniques.

Categorization of the Nine Needles

To facilitate their application, the nine needles are categorized into three groups based on their functions and techniques:
1. Needles 1-3 – Non-Insertive or Very Lightly Inserted Needles:
- These needles are primarily used for treatments, stimulating the skin, muscles and primary channels without insertion.
- They include the Arrowhead Needle (镵针, Chan Zhen), Round Needle (圆针, Yuan Zhen), and Blunt Needle (鍉针, Di Zhen).
1. Needles 4-6 for Draining Body Fluids:
- Designed to address conditions involving excess fluids, such as bloodletting, draining pus, and reducing edema.
- This category includes the Sharp-Edged Needle (锋针, Feng Zhen), Sword-Shaped Needle (铍针, Pi Zhen), and Round-Sharp Needle (员利针, Yuan Li Zhen).
1. Needles 7-9 Inserted Needles:
- These needles are the most similar to those used in contemporary acupuncture practice, intended for deeper insertion and manipulation.
- The Filiform Needle (毫针, Hao Zhen), Long Needle (长针, Chang Zhen), and Large Needle (大针, Da Zhen) fall into this group.
Each needle within these categories has specific indications and techniques associated with its use, underscoring the importance of proper selection and application in clinical practice.

Importance of Categorization

The categorization of the nine needles in the Ling Shu (灵枢) serves several key purposes in traditional acupuncture:
- Precision in Treatment: By understanding the unique characteristics of each needle, practitioners can choose the most appropriate tool for the patient’s condition, enhancing treatment efficacy. This principle is supported by Chapter 5 of the Su Wen (素问), which discusses the importance of needle depth and the specific layers of the body that need to be targeted:
- “The five depths of insertion correspond to the five layers of the body, each layer having its own therapeutic effect. The shallowest insertion treats the skin, the next level treats the flesh, the third level treats the blood vessels, the fourth level treats the tendons, and the deepest insertion treats the bones” (Su Wen, Chapter 5).
- Safety and Efficacy: Proper needle selection helps prevent adverse effects and ensures that treatments align with the patient’s specific needs. Less invasive interventions should be use when the disease is in its early stages.
- Therapeutic Versatility: The diverse range of needles allows for a broad spectrum of treatments, from superficial stimulation to deeper, more invasive interventions. This flexibility is crucial for addressing various pathologies and patient conditions effectively.
The nine needles of the Ling Shu represent a sophisticated system of acupuncture tools, each designed for specific therapeutic applications. By categorizing these needles into three functional groups, practitioners can more effectively harness their unique properties to achieve optimal clinical outcomes.

The Descriptions of the Nine Needles of the Ling Shu

The foundational text of acupuncture, the Ling Shu, outlines nine distinct needles, each with unique features and therapeutic applications. Understanding these needles is key for practitioners seeking to provide effective and precise acupuncture treatments.

Non-Insertive or Lightly Inserted Needles

These first three needles are designed for superficial treatments, primarily stimulating the skin and muscles without deep penetration.

1st – The Arrowhead Needle (镵针, Chan Zhen): This needle, with its sharp, pointed tip, is ideal for superficial pricking. It’s often used to release stagnation, stimulate qi flow, and address conditions like heat rashes and localized pain. The technique involves light, quick pricking motions. It treats the most yang levels.

This needle is commonly used in traditional Japanese medicine as the Zanshin. This variation on the classical needle has added functionality of sweeping strokes to gently stimulate the channels.

2nd – The Round Needle (圆针, Yuan Zhen): With its rounded, blunt tip, this needle is used for gentle massage and pressure on acupoints and meridians. It’s effective for treating muscle tension, spasms, and areas of qi stagnation. The technique involves pressing and massaging with the rounded tip.

In traditional Japanese medicine this tool is known as the Enshin and is commonly employed to disperse areas of excess (trigger points) and for rubbing and massage techniques.

3rd – The Blunt Needle (鍉针, Di Zhen): This needle features a flat, blunt end designed for pressing and spreading qi within muscle tissues without breaking the skin. It’s used to address muscle stiffness, tension, and superficial qi blockages. The technique involves firm pressing to spread qi. It is also use for tonification of the primary channels.

In traditional Japanese medicine, this is known as the Teishin and is commonly used for contact needling, scattered needle technique, and a whole range of functions. There are Japanese practitioners who no longer use insertive needles and perform treatments using the Teishin as their primary tool.

Needles for Draining Body Fluids

The second group of needles is specifically designed for techniques like bloodletting, draining pus, and reducing edema.

4th – The Sharp-Edged Needle (锋针, Feng Zhen): This needle has a triangular, sharp tip for shallow, precise incisions. It’s used to release small amounts of blood to expel heat and toxins and treat conditions like localized swelling and superficial infections.

5th – The Sword-Shaped Needle (铍针, Pi Zhen): Featuring a broad, flat blade, this needle is designed for deeper incisions to drain larger amounts of fluids like pus or blood. It’s used for abscesses and deep-seated infections.

6th – The Round-Sharp Needle (员利针, Yuan Li Zhen): This unique needle has a rounded body with a sharp point, and is shaped like a calligraphy brush. It is used for drain edema and fluids from tissue.
Needles Similar to Modern Acupuncture Needles

The final three needles closely resemble those used in contemporary acupuncture.

7th – The Filiform Needle (毫针, Hao Zhen): This thin, flexible needle is used for deep insertion into acupuncture points and meridians. It’s essential for manipulating qi and blood in deeper layers, treating internal organ disorders, chronic pain, and deep-seated qi stagnation.

8th – The Long Needle (长针, Chang Zhen): Characterized by its extended length, this needle is used for deep needling in thick muscles and deep tissues. It’s effective for conditions like deep muscle pain, sciatica, and issues affecting deeper body layers.

9th – The Large Needle (大针, Da Zhen): With its thicker, sturdier body, this needle is designed for robust stimulation and moving large amounts of qi and blood. It’s used for severe pain, large areas of stagnation, and chronic conditions requiring strong stimulation. It is also associated with warm needle techniques.
The Importance of Correct Needle Selection

Selecting the right needle is paramount in acupuncture. The Ling Shu emphasizes that using the wrong needle can lead to ineffective treatment or even worsen the patient’s condition. Each needle’s design, purpose, and associated techniques must be thoroughly understood to ensure safe and effective treatments.

IX. Conclusion

The nine needles of the Ling Shu represent a sophisticated and nuanced approach to acupuncture, highlighting the depth of traditional Chinese medicine’s understanding of therapeutic tools and techniques. By categorizing these needles into three functional groups— non-insertive, fluid-draining, and modern-style needles—practitioners can achieve precise and tailored treatments for a variety of conditions. By mastering these tools, practitioners can deliver precise, effective, and personalized treatments, honoring the legacy of traditional Chinese medicine while meeting the needs of modern healthcare.

Qi is Not a Thing in TCM!
The word “Qi” (氣) is everywhere in discussions of wellness, spirituality, and traditional Chinese medicine. But what if the way we commonly think about Qi is fundamentally wrong? What if Qi is not a thing? We often hear Qi described as a mystical energy, a vital life force flowing through our bodies… but that’s not quite accurate. Qi is not a thing!

Qi: Not a Noun, but a Verb

The confusion arises when we think of Qi as a noun, as something you can possess or store. In reality, Qi is more like a verb. It’s a way to describe the optimal function of a system. Think of it this way: when talking about a body with “strong Qi”, we’re describing how well its systems work:
- Wei Qi: Describes the protective functions of the immune system and the body’s ability to resist external pathogens. It doesn’t refer to a quantifiable substance but to the strength and integrity of this system.
- Yuan Qi: Represents the deep vitality inherited from our parents and maintained through the proper functioning of our organs. We can’t isolate “Yuan Qi” – it’s reflected in energy levels, resilience, and overall health.
- Zang Fu Qi: Each organ (Zang Fu) has its specific Qi. For instance, Heart Qi relates to the Heart’s ability to circulate blood and house the spirit (Shen). This Qi is not tangible, but its optimal function is critical for both physiological and psycho-emotional health.
These are descriptors of how systems in the body function, not signs of some magically undetectable substance flowing within. Also note that when the word Qi is used by itself it is vague to the point of being meaningless. We must connect it to the system it is describing (eg., Wei Qi, Yuan Qi, etc.) Simply saying a patient has deficient Qi tells us almost nothing until the type of Qi is defined.

Qi is Not a Thing… It’s Like “Digestion”

Consider the word “digestion.” When I say, “The patient has poor digestion,” I don’t mean there’s a lack of a substance called “digestion.” It’s a descriptor – perhaps the Spleen and Stomach aren’t transforming food properly, the transportation and absorption of nutrients are compromised, or Dampness is obstructing the smooth flow of Qi. From a TCM perspective, we don’t aim to infuse the patient with more “digestion,” but rather address the underlying disharmonies hindering this process.

Similarly, when we say someone has “weak Qi,” we’re not implying a deficiency of some quantifiable entity. Instead, it’s a shorthand for identifying imbalances or blockages within specific systems in the body. A TCM practitioner’s goal isn’t to directly supplement Qi, but rather to assess the root of the disharmony (whether it’s Qi deficiency, Qi stagnation, Blood stasis, etc.) and employ acupuncture, gua sha, herbal formulas, or other modalities to restore the body’s natural processes and thus its optimal functioning—or, its Qi. Chapter one of The Ling Shu states,”All acupuncture is to tonify what is deficient and reduce what is in excess” it does not mention injecting the body with Qi.

The Clock: Yin, Yang, and Qi

A perfect example of this concept is a well-designed clock. The gears, hands, and battery are Yin – the physical structure. The ability for the hands to move, the actual energy from the battery is Yang. A clock with good Qi seamlessly fulfills its purpose due to a harmonious design. Let’s consider this through the lens of TCM:
Clock with Excess Qi: A clock that runs fast might be described as having excess Yang Qi. This reflects a system where function is overactive and possibly out of sync with its intended rhythm.

Clock with Deficient Qi: A clock that runs slow could be seen as a deficiency of Yang Qi, potentially with underlying Yin aspects like Cold or Dampness hindering its function.

Broken Clock: A clock that doesn’t tell time at all has lost its fundamental function. Here, we might see a severe blockage or stagnation of Qi, or a significant mismatch between its form (Yin) and ability to function (Yang). When Yin and Yang separate a thing ceases to be. We might say a clock that does not tell time is no longer a clock. It is now a decorative wall hanging.
Furthermore, a thing is often defined by its function. If we take a broken clock down from the wall and eat off of it, it becomes a plate. While the plate may be poorly designed because its original form (Yin) was intended for a different purpose, its new function redefines its role and relationship within the larger context. Yin and Yang are not mutually exclusive; function and form must be in harmony for optimal Qi.

Qi, Blood, and TCM

Qi isn’t a tangible substance, but rather a concept describing optimal function. This is evident in Traditional Chinese Medicine (TCM), where Qi is closely linked to Blood (Xuè). If we chang the way we talk about Qi (Yang) and Blood (Yin) things make a little more sense.
- Qi as Force (Qi is the Commander of Blood): Instead of stating Qi propels Blood, it may be more accurate to say that a system with strong Qi experiences healthy blood circulation, preventing stagnation. This rephrasing may seem like semantics but the paradigm shift it evokes is profound.
- Qi as Containment (Qi Holds Blood): Rather than thinking a substance called Qi is directly keeping Blood in vessels, we should understand that a system with strong Spleen Qi (or in some cases Kidney Qi) maintains Blood within its proper channels. This is a nuanced shift in thinking but an important one.
Qi and Blood represent a yin-yang pair in TCM. Blood (Xuè) nourishes the physical body (Yin), while Qi represents dynamic functions and processes (Yang). All the blood tests in the world will never find a substance called Qi being carried by the blood. And that’s OK.

Conclusion: The Power of Qi in TCM

While the concept of Qi might initially be elusive, its value in TCM is undeniable. By shifting our understanding from “a thing” to “a descriptor of function”, Qi serves as a powerful framework for diagnosis and treatment. It transcends simplistic notions of mystical energies, grounding us in the body’s interconnected systems and natural rhythms. When we understand Qi as a descriptor of function – not a substance – a more nuanced and effective approach to treatment emerges.

By recognizing that “Qi” encompasses the harmonious interaction of Yin and Yang, the efficient functioning of our organs (Zang Fu), the strength of our defenses, our vitality, and the smooth flow of blood, we gain invaluable insights into the patterns of health and disease. When we perceive Qi as a tapestry of functions rather than a tangible entity, we become adept at identifying the subtle cues that indicate disharmony. As acupuncturists and herbalists we can leverage these ideas to guide our patients toward optimal health through balance.

This understanding of Qi as function is not merely a theoretical exercise. It has direct applications in our clinical practice:
- Precise Diagnosis: We can more easily move from vague descriptions like “weak Qi” to precise TCM concepts (Spleen Qi Deficiency, Liver Qi Stagnation, etc.). This helps us identify the disharmony at the root of the problem, leading to more targeted interventions.
- Holistic Treatment: Our choice of acupuncture points, herbal prescriptions, and lifestyle recommendations becomes deeply rooted in addressing disharmonies rather than chasing symptoms.
- Preventative Care: When we understand Qi as function, we can more easily observe subtle imbalances long before they manifest as severe illnesses. This empowers us to support our patients’ innate capacity for health and self-regulation.
Viewing Qi as a mystical substance gives us no tangible insight into the patient’s condition. Understanding form and function, yin and yang, does. Let’s continue to embrace the true power and potential of Qi as we guide our patients toward lasting well-being.

The Energetic Properties of Metals in the Healing Arts

Metals have long been used in the healing arts for their unique properties and energetic qualities. In Japan, the type of metal used in teishin-based acupuncture techniques, such as shonishin, Tyohari School, or Funamizu Style treatments, is often a primary consideration. The best metal used for a facial gua sha tool can be determined by the user’s complexion, and creating the correct bronze alloy for a singing bowl is a critical factor in its resonant qualities. Each metal has its unique personality that can be enhanced or shaped using the appropriate techniques.

In this article, we will explore the energetic qualities of different metals commonly used in the healing arts, such as copper, silver, gold, bronze and platinum, and discuss their uses and benefits. We will also discuss some scientific evidence supporting the use of metals in this way and provide tips for incorporating metal-based therapies into your healing practice.

Silver is a cool nourishing rain washing away the dirt on a warm summer day.

One of the most widely used metals in the healing arts is silver. This precious metal is known for its potent antimicrobial properties, which make it an effective tool for fighting infection. In fact, silver has been used for centuries as a natural remedy for a wide range of health conditions, including wounds, burns, and even cancer. In addition to its antimicrobial properties, silver has calming and soothing effects on the mind and body. Some healing arts practitioners even use silver to help promote restful sleep and reduce anxiety.

Silver in East Asian medicine is traditionally considered sedating and can easily transmit the practitioner’s intention. Since silver takes on the practitioner’s intention so well, it is often the best choice for a first teishin. From a physics standpoint, silver is the most thermally and electrically conductive metal. The two types of silver used are fine silver and sterling silver. Fine silver is over 99.9% pure and is slightly softer than sterling. It offers purer energetics and is somewhat more sedating. Sterling silver is 92.5% silver and 7.5% other metals (usually copper). Sterling has a flatter, energetic feel but offers slightly superior durability making it ideal for tools used for scraping and rubbing. Silver is often used as a polarity agent or Yin-Yang pair with gold.

Gold is a bright ray of the sun over a fertile field.

This precious metal is known for its lustrous yellow color and its versatility. In east Asian medicine, it is thought of as tonifying, slightly warm, and easy to manipulate. Solid gold teishin are heavy in weight and have a bright, lively feel. They are fast-acting, so practitioners must be careful not to over-treat patients when using teishin or other tools made from gold. Gold is traditionally linked to longevity, clarity of the soul, and spiritual enlightenment.

Gold-plated healing implements are popular for their cheap price, but this comes with a significant drawback. Gold plating is extremely thin, usually 0.25 – 5 micron range (0.00001″ -0.0002″), and has little effect on the energetics of the metal. In fact, the material that has been plated, usually aluminum or pot metal, will have more impact on the tool than the tiny amount of gold used to plate it. Gold-plated teishin with lightweight aluminum cores have become popular in recent years due to the lower price. Unfortunately, these teishin usually have the dull energetic quality you would expect from aluminum.

Silver and Gold as a Yin-Yang Pair

In Japanese acupuncture, silver and gold are often used together as a yin-yang pair. This is because the two metals have opposing, yet complementary, effects on the body. For example, silver has cooling and soothing properties, while gold has warming and stimulating effects. Therefore, practitioners can provide a more balanced and effective therapeutic approach by combining these two metals.

Silver and gold teishin are often used as polarity agents for Manaka-style acupuncture treatments to stimulate the flow of qi in specific directions through the channel systems. This approach is commonly used to balance the Eight extraordinary vessels.

Copper is warm blood continuously cycling through the body.

This reddish-brown metal is known for its ability to conduct electricity and heat, which makes it a popular choice for various therapeutic applications. In East Asian medicine, copper is considered slightly tonifying without being too warm. In addition, it has an affinity to the blood level, which makes it an excellent choice when treating Luo Channel issues. In Traditional Chinese medicine, the luo channels are connected to memory and mental health. When these channels become blocked or imbalanced, it can lead to various mental health problems, such as memory loss, confusion, or anxiety.

Copper offers excellent corrosion resistance and has potent antimicrobial and anti-viral properties, which make it an effective tool for fighting infection. Hospitals and medical clinics have recently started coating door knobs and other commonly touched items with a thin layer of copper to help fight the spread of infections. This property makes copper an ideal choice for acupuncture guide tubes.

The antimicrobial properties and blood level actions also make copper the perfect choice for gua sha tools. Copper is also often used in teishin by students who are not ready to invest in gold. This is better than gold plating for a practitioner on a budget.

Zinc is empty, like a dry riverbed waiting to be filled.

This bluish-white metal is known for its versatility and ability to resist corrosion, making it a popular choice for various therapeutic applications. Zinc is often taken as a supplement to boost the immune system and protect against infection. Topically, zinc is used to help improve skin health and reduce the appearance of scars and blemishes.

Copper and zinc as polarity agents.

Copper and zinc discs are often paired in Manaka-style polarity treatments. If you remember 6th-grade science class and potato batteries, you know zinc and copper are often used in a dielectric to produce an electrical charge. Zinc is used as the negative electrode, or anode, while copper is used as the positive electrode or cathode. By combining these two metals, scientists can create a simple battery using a potato as an electrolyte. In Manaka-style acupuncture treatments, the patient is the dielectric. Dr. Yoshio Manaka originally developed this treatment method to speed healing in patients suffering from burns and later adapted it to his acupuncture system.

Platinum is a singularity with all its potential; explosive and life-giving.

This rare, silvery-white metal is known for its strength, durability, and ability to withstand high temperatures. Platinum is very tonifying, hot, and difficult to control. It is often used to improve mental clarity and focus. Care should be taken with platinum as it is easy to over-treat when using tools made from this material. Platinum tools are often prohibitively expensive, not only because of the cost of the material but its exceptionally high melting point (3,215°F) makes it difficult for artisans to work with it.

Bronze is full of potential, waiting to be forged into resonance.

Bronze is an alloy of copper and tin, and possesses a stiff, resonant quality. While copper itself has a warm, tonifying nature, the addition of tin gives bronze a neutral feel that is brimming with potential. Historically, bronze was among the first materials used for acupuncture needles, though it was eventually superseded by the stiffer and more durable steel. The original Nine Needles described in the Huang Di Nei Jing Ling Shu were likely forged from bronze.

The tradition of using bronze for singing bowls and bells dates back centuries and highlights its unique properties. These instruments, when played by a skilled musician or practitioner, produce intricate harmonic vibrations. Singing bowls, in particular, generate a soothing sound known for its therapeutic benefits. Beyond their sonic qualities, singing bowls hold a rich spiritual history, often integrated into various meditative and ceremonial practices.

Iron is a soft muddy field; it is difficult to traverse but will eventually bring new life.

Iron is a key component in our blood. It is neutral in its unoxidized state, but as it rusts, it becomes warmer. Magnetite is one of the main iron ores, with the chemical formula Fe3O4, and is used extensively in the healing arts to neutralize negative emotional states such as fear, anger, and depression. Magnets are also worn to relieve inflammation and pain associated with arthritis.

Iron is not generally used in modern acupuncture tools, probably due to its ease of corrosion. It was, however, used in ancient times before the development of high-quality steel. Please note only some steel contains iron; therefore, steel is only a reliable replacement for iron if the exact composition is known.

Steel is a clear, crisp winter night spent gazing at the stars.

Steel is an alloy, and its exact combination of metals will differ from steel to steel. The steel used in your kitchen knife differs from the steel used in your frying pan. They have been formulated for different purposes and require compositions of base metals. Steel is generally neutral and tends to feel flat and cold unless manipulated. Most modern acupuncture needles are made from steel. Modern surgical tools are often made from stainless steel for their durability and ease of sterilization.

Titanium is inert and unmoving, like the universe before the first sound.

This metal is very durable and lightweight but has very low electrical and thermal conductivity. It is incredibly flat and neutral energetically and is not commonly used in traditional healing arts. However, its often used in surgeries and prosthetics due to its inertness.

The Physical Properties of Metals

The chart below compares the physical properties of metals commonly used in the healing arts. For example, the most frequently used metals for teishin (silver, copper, and gold) are also the most electrically and thermally conductive. On the other hand, the materials used in most modern medical applications (titanium and stainless steel) have the least electrical and thermal conductivity and the highest hardness. The last column in the chart lists the traditional ideas on sedation versus tonification and is given as a frame of reference for comparative purposes.

Conclusion

The use of metals in the healing arts is a centuries-old tradition that is still relevant today. Each metal has unique properties and energetic qualities that can promote health and well-being in different ways. Some metals, such as silver and gold, are known for their conductive properties and make excellent teishin. Others, such as copper, with its antimicrobial properties and affinity to the blood, make excellent gua sha tools. Bronze is known for its resonant qualities and is often a choice material in sound healing. Choosing the most suitable metal for your healing implements can create a synergy that can bolster and amplify your work as a healing practitioner.

Whether you are a seasoned practitioner of the healing arts or simply looking for new ways to promote your health and well-being, exploring the energetic qualities of metals can be a valuable addition to your wellness routine. By learning about the unique properties and uses of different metals, you can make informed decisions about which ones may best suit your individual needs healer.
