Prevent Backward Inference of Causes
A current appearance of kidney deficiency does not establish that someone was weak from birth.
L0 in Three Minutes
Conclusion: L0 Does Not Simply Mean “Innate Constitution”
It preserves what was established by birth as facts accompanied by records and information sources, rather than inferring it from current findings.
Before/at Birth and After Birth
L0 extends through birth. L1 is the ordinary baseline formed through postnatal life, development, medical history, and treatment history.
Interview and Verification
Clarify why pregnancy, birth, development, and family information are sought, and update hypotheses through subsequent treatment course.
Current PositionCreation of L0, its boundary with L1, and six basic questions confirmed by Koichi IshiharaFormal layer naming, variant-edition collation, and clinical verification remain ongoing

Clinical question
Why L0 Became Necessary
The earlier version allowed conditions established by birth and the ordinary baseline formed afterward to become mixed under the single explanation of constitution.
1Same Present FindingsA similar disease label or appearance of kidney deficiency
2Different Formation PathwaysPresent at birth / formed over time / first arose later
3Different Clinical JudgmentsPriorities, response times, and remaining constraints may differ
4Therefore Preserve Them SeparatelyDo not lose when the condition formed or the source of the information
Koichi Ishihara's Clinical Question
Can “present from birth,” “formed during development,” and “appeared after a later event” all be compressed into constitution? This question initiated the creation of L0.
L0Established by Birth
Confirmed facts about pregnancy, prenatal formation, delivery, and birth
→
L1Formed after Birth
The ordinary baseline formed through life, development, medical history, and treatment history
Boundary rule:Separate by when formation can be confirmed, not by when it was discovered.
Derivation
From Classics to L0: Four Stages of Derivation
The classics do not describe a layer called L0. Ishihara reconstructed continuities visible across ten passages into a clinical information structure.
Understanding Life's Formation as Whole-Body Formation
天之在我者德也、地之在我者氣也。德流氣薄而生者也。故生之來謂之精。兩精相搏謂之神。Lingshu, Benshen, section 2
人始生、先成精、精成而腦髓生、骨為幹、脈為營、筋為剛、肉為牆、皮膚堅而毛髮長、穀入于胃、脈道以通、血氣乃行。Lingshu, Jingmai, section 2
願聞人之始生、何氣築為基、何立而為楯、何失而死、何得而生。……以母為基、以父為楯。失神者死、得神者生也。……血氣已和、營衛已通、五藏已成、神氣舍心、魂魄畢具、乃成為人。Lingshu, Tiannian, sections 1–2
Content in the original textThe text describes life, essence, spirit, body parts, parents, blood and qi, construction and defense, and the five zang as a continuum involved in a person's formation.
Reconstruction through MLMNL0 preserves initial conditions for the formation of whole-body structure and function, rather than serving only as a shelf for genetics.
What this does not establishEquating classical essence with DNA, or mechanically predicting present pathology from parental conditions.
Connecting Prenatal Events with Postnatal Onset through Time
帝曰、人生而有病巔疾者、病名曰何、安所得之。歧伯曰、病名為胎病。此得之在母腹中時、其母有所大驚、氣上而不下、精氣并居、故令子發為巔疾也。Suwen, Qibing Lun, section 9
Content in the original textFor one pathological presentation, the text relates an event in the mother's womb to later onset and describes it as fetal illness.
Reconstruction through MLMNRecord the origin of formation and the interval to onset separately from the time of onset itself.
What this does not establishExplaining all congenital tendencies through maternal emotions, or treating classical causal claims as modern medical facts.
Viewing Parents, Prenatal Formation, and Postnatal Nurturing as a Continuum
人稟父母精血化生。……故人之賦稟、自受氣至胎化、自成形至生養、亦皆由焉。Xiao'er Weisheng Zongwei Lunfang, volume 1, Binshou Lun
Content in the original textThe text discusses what is received from parents, reception of qi, fetal formation, bodily formation, and nurturing after birth as one sequence.
Reconstruction through MLMNSeparate conditions through birth as L0 from postnatal nurturing as L1 while retaining their connection.
What this does not establishEquating parental essence and blood with modern inheritance mechanisms, or fixing later outcomes from prenatal conditions alone.
Checking Unremembered History Backward through Developmental Records
小兒在胎時、其母將養傷於風冷、邪氣入胞、傷兒臟腑。故兒生之後、邪猶在兒腹內。Zhubing Yuanhou Lun, volume 47, Crying Manifestation
若稟生血氣不足者、即髓不充強、故其骨不即成、而數歲不能行也。Zhubing Yuanhou Lun, volume 48, Inability to Walk after Several Years
小兒稟生血氣不足、即肌肉不充、肢體柴瘦、骨節皆露。Zhubing Yuanhou Lun, volume 48, Crane-Joint Manifestation
有因父母稟受所生者、胎弱胎毒是也。……子之羸弱、皆父母精血之弱也。Wan Quan, Youke Fahui, volume 1, Fetal Disorders
夫男女之生、受氣於父、成形於母。故父母強者、生子亦強。父母弱者、生子亦弱。Same section, Fetal Disorders
Content of the Originals and Later Medical WorksThe texts relate prenatal conditions, congenital insufficiency, developmental findings such as walking and body build, and conditions received from parents.
Reconstruction through MLMNReturn to family accounts, maternal-and-child health handbooks, and medical records, obtaining pregnancy, birth, and development as separate facts.
What this does not establishDeterminism that weak parents necessarily produce weak children, or inferring prenatal causes from present findings.
From classics to interview
Translating Classical Research into Six Answerable Questions
Patients are not asked about classical terminology. Temporal information that the classics indicate should not be lost is translated into language about verifiable facts.
Congenital Diagnoses or Explanations
Diagnoses or explanations from medical institutions about bodily structure or function.
Condition at Birth
Gestational age, birth weight, difficult delivery, breathing, incubator use, hospitalization, and surgery.
Maternal Conditions during Pregnancy
Major illness, infection, accidents, hospitalization, and ongoing medication.
Infant and Early-Childhood Development
Delayed growth or development, treatment, training, and special support.
Biological Family Information
Similar conditions, congenital disorders, and serious illnesses with young onset.
Changes after Treatment
What improved after treatment, surgery, or training, and what remains today.
Why Ask People Other Than the Patient?
Adults do not directly remember their own gestation or birth. With consent and where possible, consult parents or family, maternal-and-child health handbooks, clinical records, and test results. If unknown, do not infer: retain “unknown” as a valid answer.
Current definition
Current Definition of L0 and Information It Must Not Contain
L0 preserves confirmed facts concerning bodily form, function, vulnerability, and constraints established by birth through parental preconception conditions, conception, prenatal formation, pregnancy, and delivery. It is a starting point for examining how these may have contributed to postnatal long-term foundations, reactions to etiological inputs, and current pathology.An MLMN reconstruction, not a direct quotation from a classical text.
Include in L0
- Diagnoses and structural or functional differences confirmed from birth
- Gestational age, birth weight, delivery course, and procedures at birth
- Maternal illness, infection, medication, and exposure during pregnancy
- Health handbooks, clinical records, test results, and specific family information
Do Not Place Directly in L0
- Congenital insufficiency inferred from present findings
- Postnatal infection, injury, drug harm, nutrition, or nurturing conditions
- Classical mechanism names such as kidney deficiency or fetal toxin themselves
- The patient's pathology inferred from family history alone
What AI Did
Candidate search, passage extraction, classification, and detection of repeated text, OCR errors, distinctions between text and commentary, and attribution differences.
What Koichi Ishihara Did
Posed the clinical question, judged inclusion and boundaries, and reconstructed the classical descriptions as L0. Final diagnostic and treatment judgment remains with the practitioner.
Falsification & status
What Findings Would Revise the L0 Hypothesis?
Conditions for Refutation or Revision
- Birth or development records disagree with the hypothesis
- First onset clearly followed an event later in life
- Family recollection and medical records disagree
- Another pathway is established, such as structural disease, infection, injury, or medication
- Predicted treatment responses repeatedly fail to match
- The hypothesis cannot explain cases with the same initial conditions but without the pathological state
Current Verification Status
- New Layer and Boundary
- Confirmed by Koichi Ishihara
- Basic Interview
- Six questions plus information-source tags
- Direct Quotations
- Five works, ten passages
- Image Comparison
- Cited locations in all five works
- Variant-Edition Collation
- Incomplete
- Clinical Verification
- Supporting and contradictory evidence being accumulated
Do not conflate three states:“A factor is confirmed,” “no factor is present,” and “information is unknown” are different states. Missing information is not proof that a factor did not exist.
What This Page Establishes
We publish the reason for adding L0, the scope of 49 works, the five directly cited books and ten passages, six basic questions, and refutation conditions. Formal naming, variant collation, and clinical supporting and contradictory evidence remain subject to updates.
MLMN is an original framework under research. This page organizes theory for research and education and does not replace diagnosis, treatment, or prescribing decisions.
