What is Traditional Chinese Medicine and how does it work

TCM (Traditional Chinese Medicine) is a section of Chinese traditional medicine. The majority of its therapies have been regarded as having no logical mechanism of action, and it has been categorized as "fraught with pseudoscience."

The Compendium of Materia Medica and the Huangdi Neijing is said to be the foundations of TCM. Herbal treatment, exercise (qigong), cupping therapy, acupuncture, gua sha, bonesetter (die-da), massage (tui na), and nutritional therapy are also part of the activity. TCM is commonly practised in the Sinosphere, which has a rich history. As a result, it is now practised in other countries as well. One of TCM's essential tenets is that the body's vital energy (ch'i or qi) circulates across meridians, which have branches that bind to various bodily organs and functions. Vital energy is a pseudoscientific term. TCM's body and disease concepts are based on its ancient roots and emphasise complex processes over material structure, close to Ancient Greece and Rome's humoral theory.

History of Chinese Herbal Medicine

In the Sinosphere, which does have a long ancient Chinese medicine history, TCM is commonly used. The Yellow Emperor's Inner Canon and the Treatise on Cold Harm, and also cosmological concepts like yin–yang and the five stages, are the foundations of Chinese medicine. Such precepts became standardised in the People's Republic of China beginning in the 1950s, and attempts have been made to combine them with modern notions of pathology and anatomy. The Chinese government introduced a systematised model of TCM in the 1950s.

Shang Dynasty: The Shang dynasty left traces of therapeutic practises in China. Even though Shang might not have such a distinct definition of "medicine" from all other areas. Oracular inscriptions on bones and tortoise shells relate to diseases that afflicted the Shang royal family, such as toothaches, swollen belly, eye disorders, and other ailments that Shang elites generally would relate to curses sent through their ancestors. There is no proof that the Shang aristocracy employed herbal medicines at this time. "Documentation of Chinese materia medica dates back to about 1,100 BCE, when only hundreds of drugs had first been identified," according to a 2006 overview. The number of medications recorded had risen to nearly 1,900 by the end of the 16th century. And by the turn of the century, CMM had amassed a total of 12,800 drugs in its database."

Han dynasty: The Yellow Emperor's Inner Canon (Huangdi Nei Jing), the ancient research of Chinese medical theory, has been done on the basis of shorter texts from various medical lineages during the Han dynasty from around the 1st century BCE. It is expressed in the form of conversations between the legendary Yellow Emperor and his ministers, and it explains the relationship between humans, their world, and the universe, as well as the nature of the body, human vitality and pathology, disease symptoms, as well as how to render diagnostic and therapeutic decisions in view of each of these factors.


Ancient Chinese Treatment in Women

Pregnancy: Pregnancy has been recognised in Western medicine since the publication of the Hippocratic Corpus in the gynaecological treatises On the Diseases of Women, On the Nature of the Woman, Generation, On the Nature of the Child, On Fistulae, On Sterile Women, and On Hemorrhoids, between the mid-fifth and mid-fourth centuries BCE. The word ‘Caesarean section’ comes from an ancient Roman (from Caesar) rule that stated that if a pregnant lady expired, her body could not be buried until the unborn child was expelled. However, it was prohibited for ancient Roman doctors to treat this operation on living women.

Postpartum: If both the baby and the mother made it through the pregnancy, childbirth would have been the next step. Towels to collect the blood, a tub for the placenta, a maternity sash to protect the uterus, and an infant swaddling wrap were among the birthing supplies. The child was born, washed, and swaddled with all of these tools; nevertheless, the doctor right away focused on the mother to replenish her qi (i.e. vital energy which is believed to circulate the body in currents). 

Dr Cheng emphasises the Four Diagnostic Methods for dealing with postpartum problems in his writings, and advises all physicians to "not ignore any [of the four methods]." Since it was believed that giving birth depleted a woman's blood and qi, the most popular postpartum remedies were diet (usually garlic and ginseng), medication, and rest. This was accompanied by a month-by-month check-in with the doctor, a procedure known as zuo yuezi.

Infertility: Infertility was still poorly understood in TCM, but it had significant social and cultural consequences.

Sun Simiao, a 7th-century scholar, was among the most cited scholars when it comes to female health. "Anyone who has prescriptions for women's distinctiveness uses their disparities of childbirth, pregnancy, and bursting accidents as their basis," he is quoted as saying. Sun's findings regarding female reproductive roles are still relevant in today's world, and it is an important feature of women's health. The tendency to put a greater focus on reproductive functions than on a woman's overall health suggests that the primary role of fu ke is to make babies.


Chinese Herbal Medicine

Although plant elements seem to be the most widely employed products in TCM, other, non-botanic substances are often used, including human, animal, and mineral items. As a result, the word "medicinal" (rather than "herb") can be used, despite the fact that no empirical evidence exists that either of these compounds possess medicinal properties.


Raw Materials:

In China, approximately 13,000 compounds have been used, with over 100,000 TCM recipes documented in ancient literature. Plant extracts and elements are perhaps the most commonly used elements. There were 517 drugs mentioned in the 1941 Handbook of Traditional Drugs, 45 of which have been animal parts and 30 minerals.


Animal Substances:

Cow gallstones, leeches, hornet nests, and scorpions are only a few of the unusual animal parts included. Animal parts comprise antelope or buffalo horn, dog testicles, deer antlers, and penis bone, and snake bile, among others.

While some TCM textbooks often recommend animal-tissue preparations, there seems to be little evidence to support the alleged clinical efficacy of several TCM animal products.


Human Body Parts: 

The classic Materia medica (Bencao Gangmu) defines (and criticises) the use of 35 human body parts and excreta in medicines, namely faeces, bones, fingernails, skin, earwax, dandruff, impurities on the teeth, saliva, urine, and organs, but the majority are not currently in use.

The human placenta is often used as an element in some traditional Chinese medicines, such as the treatment of impotence, infertility, as well as other disorders with dried human placenta, classified as "Zieche." The ingestion of the human placenta poses a risk of infection.

FAQs on Traditional Chinese Medicine Principles and Practices

1. What is Traditional Chinese Medicine (TCM)?

Traditional Chinese Medicine (TCM) is a holistic medical system that aims to balance the body’s vital energy, known as Qi, to maintain health and treat disease. It is based on concepts such as:

  • The flow of Qi through energy pathways called meridians
  • The balance of Yin and Yang
  • The interaction of the Five Elements (Wood, Fire, Earth, Metal, Water)

TCM includes practices like acupuncture, herbal medicine, cupping, tai chi, and dietary therapy.

2. What is Qi in Traditional Chinese Medicine?

In Traditional Chinese Medicine, Qi is the vital life force or energy that flows through the body and sustains physiological functions. According to TCM theory:

  • Qi circulates through meridians
  • Balanced Qi supports normal organ function
  • Blocked or deficient Qi is believed to cause illness

Although Qi is not directly measurable in modern biology, it is often compared conceptually to processes like metabolism and cellular energy regulation.

3. How does acupuncture work biologically?

Biologically, acupuncture works by stimulating specific points on the body to influence the nervous, endocrine, and circulatory systems. Scientific studies suggest it may:

  • Trigger release of endorphins (natural pain-relieving chemicals)
  • Modulate neurotransmitters such as serotonin
  • Improve local blood circulation
  • Reduce inflammation through immune signaling pathways

These mechanisms may help explain its use in pain management and stress-related disorders.

4. What are meridians in Traditional Chinese Medicine?

In Traditional Chinese Medicine, meridians are theoretical pathways through which Qi flows throughout the body. TCM describes:

  • 12 primary meridians linked to major organs
  • Additional secondary and extraordinary channels
  • Specific acupuncture points located along these pathways

While meridians do not correspond directly to anatomical structures like nerves or blood vessels, some researchers explore possible links to connective tissue planes and neurovascular bundles.

5. What is the concept of Yin and Yang in TCM?

The concept of Yin and Yang in TCM describes complementary and opposing forces that must remain balanced for health. In biological terms:

  • Yin is associated with cooling, rest, nourishment, and structure
  • Yang is associated with heat, activity, and energy

Disease is believed to result from an imbalance between Yin and Yang, similar to how modern physiology emphasizes homeostasis for stable internal conditions.

6. What are the Five Elements in Traditional Chinese Medicine?

The Five Elements theory in TCM explains relationships between organs and natural processes using Wood, Fire, Earth, Metal, and Water. Each element is associated with:

  • A specific organ system (e.g., Liver–Wood, Heart–Fire)
  • Emotions and sensory organs
  • Cycles of generation and control

This framework is used to understand disease patterns and organ interactions rather than literal chemical elements.

7. How does herbal medicine work in Traditional Chinese Medicine?

Herbal medicine in TCM uses plant, mineral, and sometimes animal products to restore balance and support organ function. Biologically, many herbs contain:

  • Phytochemicals with anti-inflammatory effects
  • Alkaloids, flavonoids, and glycosides
  • Compounds that influence the immune system or metabolism

Formulas are typically combined to target multiple physiological pathways rather than a single symptom.

8. Is Traditional Chinese Medicine scientifically proven?

Some components of Traditional Chinese Medicine, such as acupuncture and certain herbal remedies, have scientific evidence supporting specific uses, but others remain under investigation. Research shows:

  • Acupuncture can help with chronic pain and nausea
  • Certain herbs have pharmacologically active compounds
  • More high-quality clinical trials are needed for many treatments

Scientific evaluation focuses on measurable biological mechanisms and clinical outcomes.

9. What conditions are commonly treated with Traditional Chinese Medicine?

Traditional Chinese Medicine is commonly used to manage chronic and functional conditions by promoting systemic balance. These include:

  • Chronic pain (e.g., back pain, arthritis)
  • Digestive disorders
  • Stress and anxiety
  • Menstrual disorders
  • Respiratory conditions

TCM is often used as a complementary therapy alongside modern biomedical treatment.

10. What is the difference between Traditional Chinese Medicine and modern Western medicine?

The main difference between Traditional Chinese Medicine and Western medicine is that TCM focuses on holistic energy balance, while Western medicine emphasizes cellular and molecular mechanisms of disease. Key contrasts include:

  • TCM uses concepts like Qi, Yin–Yang, and meridians
  • Western medicine relies on anatomy, physiology, microbiology, and evidence-based pharmacology
  • TCM treatments often combine multiple modalities; Western medicine targets specific pathological causes

Both systems aim to restore health but differ in theoretical foundations and diagnostic approaches.
