Sheng Nong Ben Cao Jing (Divine Farmer’s Classic of Materia Medica)

  • Oldest surviving Chinese pharmacopeia.
  • Compiled during the Han Dynasty (100-200 CE).
  • Attributed to the legendary emperor Sheng Nong.
  • Actual authors were likely herbalists of the Han era.
  • Honors Sheng Nong as the father of Chinese agriculture and herbal medicine.
  • He supposedly tasted hundreds of herbs to understand their properties.
  • First systematic attempt to categorize medicinal substances.
  • China's First Pharmacopeia (earliest systematic manual of herbal medicine).
  • Originally divided into three volumes, with 365 herbal entries.
  • Each herb is classified by key therapeutic attributes:
    • Nature/temperature
    • Taste
    • Channel tropism
    • Primary clinical actions

Example: Mahuang (Ephedra)

  • Nature: Warm, hot.
  • Taste: Pungent (opens up the lungs).
  • Tropism: Lung and bladder.
  • Primary Actions:
    • Induces sweating
    • Releases wheezing (dilates bronchial muscles).
    • Promotes urination (lung helps urinary bladder function).
  • Western medicine equivalent: Ephedrine.
    • Used for weight loss (stimulates adrenergic receptors).
    • Used for asthma, bronchitis, and allergy medication (dilates bronchial muscles).
    • Banned/heavily regulated in the US and Canada because of misuse.
  • Ancient Chinese physicians identified Mahuang's properties long before Western medicine.

Three categories of herbs:

  • Upper Grade (Upper Herbs):
    • Nontoxic
    • Tonic in nature (tonifies the body)
    • Promotes longevity and preserves health
    • Examples: Ginseng, Reishi mushroom
  • Middle Grade (Middle Herbs):
    • May have mild toxicity
    • Used for nourishing and regulating internal systems
    • Treats imbalances, not just symptoms
  • Lower Grade (Lower Herbs):
    • Strong action and often toxic
    • Example: Fuzi (highly toxic but very powerful; used for yang collapse).

Key features of each herb entry:

  • Flavor and nature
  • Meridian of penetration (aka tropism; which organ it goes to)
  • Function and indications (what it does)
  • Toxic level
  • Yin-yang balance
  • Five flavors (sweet, sour, bitter, pungent, salty)
    • Sweet taste has a tonifying effect
  • Qi (temperature: cold, hot)
  • Directional flow (ascending, descending, inward, outward)
    • Pungent herbs (like Mahuang) open up nasal pathways (outward and ascending).

Legacy and Influence:

  • Foundation for all subsequent materia medica texts.
  • Especially the Shang Han Lun and Jin Gui Yao Lue. Based on this textbook
  • Still referenced today in herb training, formulation, and clinical use.

Other Influential Medical Theories and Textbooks

Wenbing Theory (Warm Disease Theory)

  • Studied more deeply in TCM 2.
  • Developed from observations of epidemic illnesses.
  • Initially thought that diseases attack through the skin layer (Wei level), penetrating deeper if untreated.
  • Later, physicians realized that infection also occurs through the nose and mouth.
  • Led to a framework for dealing with warm diseases.
  • Four Levels in Wenbing Disease:
    • Wei Level
    • Qi Level
    • Ying Level (Nutrient Level)
    • Xue Level (Blood Level; most internal level)

Yan Tianqi developed this four-level theory.

  • Warm diseases are different from cold diseases, often with more severe symptoms like sore throat.

Sanjiao Theory

  • Studied in TCM 2.
  • Sanjiao is not an organ but more like an interstitial space in Western medicine.
  • Is a system where fluid moves through in the body.
  • Three levels:
    • Upper Jiao: Contains the lungs and heart.
    • Middle Jiao: Contains the stomach and spleen.
    • Lower Jiao: Contains the large intestine, urinary bladder, and the rest of the lower body.

Evolution of Acupuncture and Moxibustion Techniques

  • Developed alongside TCM theory.
  • Prehistoric Times:
    • Rubbing, pressing, and pain relief were found to have therapeutic effects.
    • Bian (sharpened stones) became tools for lancing abscesses and sores (releasing pus helped healing).
  • Ling Shu (Spiritual Pivot):
    • Lays out theory of meridians and points.

Zhen Jiu Jia Yi Jing (The Systematic Classic of Acupuncture and Moxibustion)

  • Compiled by Huangfu Mi.
  • First known complete manual on acupuncture and moxibustion.
  • Describes 349 acupoints.
  • Classifies points along 14 channels.
  • Organizes treatment strategies. This is Still used today in practice.
  • Integrated theoretical knowledge with clinical experience.
  • Established acupuncture as an independent medical discipline.

Tang and Song Dynasties (Golden Age)

  • Acupuncture and moxibustion were institutionalized.
  • Taught in Imperial Medical Colleges.
  • Copper acupuncture models were developed for teaching purposes.
  • Life-sized models with meridians and acupoints were used.
  • Models had movable limbs and internal structures.
  • Some models contained water to test acupuncture point accuracy and depth.

Qing Dynasty

  • Acupuncture was not widely practiced.
  • Greater focus on herbal prescriptions.
  • Emphasis on Zang-Fu (organ) theory: connecting symptoms to specific organ disorders.
  • Modern TCM: Tendency to relate symptoms to organ disorders, possibly influenced by Western medicine.
  • Need to consider channel disorders as well.

20th Century

  • People's Republic of China: TCM integrated into modern medical education.
  • 1972: New York Times reporter witnessed acupuncture anesthesia during Nixon's visit to China, spurring Western interest.
  • Today: Acupuncture is globally recognized and endorsed by the World Health Organization for numerous conditions.

Acupuncture Tools

  • Early tools: Sharpened stones.
  • Evolution to needle-like forms.
  • Modern clinic: Disposable needles.

Moxibustion

  • Paintings from Feng Dynasty show depiction of moxibustion.
  • Modern moxibustion:
    • Korean moxa is well-known.
    • Japanese loose form moxa.
    • Caustic moxa
    • Various forms for clinic use.
  • Similar practices exist in other cultures (e.g., Zimbabwe: heated bottle to treat ringworm).
  • Moxibustion:
    • Heat to suck out the toxic conditions
    • Can be amazing, but consider: don't use with heat sign in your patient.
    • Use when patient has a cold sign (diarrhea by ice cream is very good to stop diarrhea.

Fundamental Characteristics of TCM Theory

  • Nature and Body are One (shaped by Taoism).
  • Confucian ideas heavily influenced TCM.

Two Fundamental Pillars:

  • Holism
  • Syndrome Differentiation-Based Treatment

Holism

  • Integrated view of a human being in relation to body, mind, nature, and society (all are integrated).
  • Emphasizes health arising from internal harmony and alignment with external conditions.
  • Body should not be treated as isolated parts but as interconnected whole.
  • Western: Disease with a name, and treatments are done on specific symptoms.
  • TCM: External can affect internal. and disorder is made in certain type of disease.
  • heavily influenced by Taoist philosophy
Taoism
  • Human is a microcosm

  • Tao (the way) balance of yin and yang

  • Balance five elements

  • Harmonize with the nature, the universe and environment.
    *Not just nature, but your social environment as well.

  • Cosmic balance

  • Comparison of Perspectives

    • TCM: Improve balance and treat the whole not a specific disease, with clinical observations.
    • Western: Symptoms, imaging, and getting medication to target the test results, and symptoms.
      *Broader Prevention by TCM and Western focuses on managing symptoms.
      Key Contribution of Taoism is non-duality
  • Balance and Flow Interplay between Yin and Yang; always with the natural forces

  • Step For natural order dont against the, you know, natural water. Right? Like, go to bed if sunset and get eat seasonal vegetables.
    And emotional well-being in focus

Confucian

  • Shaped by the TCM's whole vision of nature and cosmos like relationship to the body and mind
  • Shaped Politics and ethnics with the harmony of society.
    *influences TCM by ethics with self dicsiline and is resposible

Pattern-Based Diagnosis (Syndrome Differentiation)

Syndrome Differentiation

  • Process of identifying underlying pattern of imbalance.
  • Understanding how and why the body is out of harmony.
  • Not just leveling diseases.
  • Includes: DISEASE / SYMPTOMS & SIGNS / SYNDROME

Disease

  • General pathological condition or diagnosis (e.g., headache, arthritis).
  • Often broad term that may apply to many individuals

Syndrome

  • Particular pattern of imbalance or dysfunction identified through clinical signs and symptoms.
  • Defines the nature, location, and cause of illness.
  • Actual focus of treatment in TCM.

Symptoms & Signs

  • Symptoms: Subjective experiences reported by the patient (e.g., fever, sore throat)
  • Signs: Visible observations by the practitioner (e.g., tongue color, pulse quality)

Example Mr. Smith vs Mrs. Smith Insomnia.

  • Mr. Smith has: Liver Qi stagnation (Difficult to fall asleep w Hyochondriac pain and red tongue).
  • Mrs. Smith has: Heart Yin deficiency (Difficulty to stay asleep, Night Sweat and dry mouth w Red tongue).

Four Diagnostic Methods

  • Inspection
  • Auscultation and Olfaction
  • Inquiry
  • Palpation the 4 ways you come up with treatment principles.
  • They can be done 3 different types or same diseases types and all 3 can be treatment Principles.

Treatment Principles

  • Same Disease, Different Treatment
  • Different Disease, Same Treatment
  • Same Disease, Different Stages
