Shennong's Classic of the Materia Medica

Supplementary Lost Texts from the Classic of the Materia Medica

A Vernacular Interpretation of "Shennong's Classic of the Materia Medica: Lost Supplementary Texts"

Overall Paraphrase

This passage consists of scattered content compiled by later generations from ancient texts of the Shennong's Classic of the Materia Medica. It is primarily introductory and theoretical in nature, rather than specific records of individual medicines. Since these are lost fragments, the text also contains interspersed annotations and quotations from later commentators and legends.

🌿 The Total Number of Medicines Corresponds to Heaven
The ancient edition states that the three grades of medicines together total 365 varieties, modeled upon the 365 days of a year—one degree corresponding to one day—to complete a full year. Later transmitted editions increased this to 730 varieties, incorporating the supplementary entries from the Miscellaneous Records of Famous Physicians. In the Song dynasty, Zhang Yuxi pointed out that the original Shennong's Classic of the Materia Medica was written in red characters, while the Miscellaneous Records of Famous Physicians used black characters. Because of prolonged transcriptional transmission, the red and black inks became confused, and content from the Later Records came to be mistaken for the original classic text. This reminds us that the words of the "Classic" we read today may contain later additions.

🌿 Formula Structure: Ruler, Minister, Assistant, Courier
Medicines within a prescription have roles as ruler (jun), minister (chen), assistant (zuo), and courier (shi), which mutually support, restrain, and assist one another. The common ratio is one ruler, two ministers, three assistants, and five couriers; alternatively, one ruler, three ministers, and nine assistants/couriers. These are not rigid rules but rather indicate that within a formula there exists a hierarchy of primary and secondary elements.

🌿 The Seven Combined Use Relationships
Medicines relate through yin-yang coordination, and through "mother-child" and "elder-younger brother" relationships. In terms of source, they may derive from roots, stems, flowers, or fruits, as well as from grasses, minerals, bones, or flesh. The combined-use relationships are divided into seven types: single use (danxing), mutual reinforcement (xiangxu), mutual assistance (xiangshi), mutual fear (xiangwei), mutual aversion (xiangwu), mutual opposition (xiangfan), and mutual killing (xiangsha). When used together, mutual reinforcement and mutual assistance are beneficial; mutual aversion and mutual opposition should be avoided. If toxic medicines require suppression, mutual fear or mutual killing relationships may be employed; otherwise, combination is inadvisable. This reflects the ancients' preliminary summary of drug interactions.

🌿 Nature and Processing of Medicines
Medicines possess the five flavors of sour, salty, sweet, bitter, and pungent; the four natures of cold, hot, warm, and cool; and may be either toxic or non-toxic. There are prescribed methods for shade-drying or sun-drying after harvesting, appropriate gathering seasons, processing through raw or cooked preparation, place of origin, genuineness versus adulteration, and freshness versus age of the materials.

🌿 Choice of Dosage Form
Some medicines are suited to being made into pills; some into powders; some to decoction in water; some to steeping in wine; some to reduction into concentrated paste; a single medicine may also be suitable for multiple dosage forms; and some cannot be made into decoctions or tinctures. The choice should follow the nature of the medicine and must not be violated.

🌿 Timing of Treatment and Prognosis
The ancients held that in treating disease, one must first examine the cause and carefully discern the pathological mechanism. If the five viscera are not yet depleted, the six bowels not yet exhausted, the blood and vessels not yet disordered, and the spirit not yet scattered, the patient may easily recover after taking medicine. If the disease has already become established, only partial recovery may be possible. If the pathological momentum has already passed, life may be difficult to preserve. This emphasizes early treatment and prevention before illness arises, while also embodying a simple ancient judgment regarding the prognosis of critical illness.

🌿 Usage of Toxic Medicines
When using poisonous medicines for treatment, the initial dosage must be extremely small, as fine as millet grains. Stop once the illness subsides; if there is no improvement, the dose may be doubled; should it remain ineffective, it may be increased up to tenfold. In all cases, the criterion is the retreat of the disease—do not exceed the proper measure. This represents an extremely early approach to dose escalation, but the original statements of "double it" or "ten times it" should not be mechanistically reproduced in modern practice.

🌿 Cold, Heat, and Treatment Based on Disease Location
Cold diseases are treated with hot medicines; hot diseases with cold medicines. Indigestion from improper diet is treated by emesis or purgation. So-called "guizhu" (corpse transmission) and "gudu" (poisoning by curses/worms) are treated with toxic medicines. Abscesses, tumors, ulcers, and swellings are treated with ulcer medicines. Wind-damp diseases are treated with wind-damp medicines. Each condition follows what is appropriate. The "guizhu" and "gudu" mentioned here are ancient terms for certain infectious diseases, parasitic conditions, or intoxications, and do not imply the actual presence of ghosts or evil spirits.

🌿 Timing for Taking Medicine
For diseases above the chest and diaphragm, one should eat first, then take medicine. For diseases below the heart and abdomen, one should take medicine first, then eat. For diseases in the limbs and blood vessels, it is suitable to take medicine in the early morning on an empty stomach. For diseases in the bone marrow, it is suitable to take medicine at night with a full stomach. These are the ancients' empirical observations on the relationship between the time of administration and the location of illness.

🌿 Examples of Major Illnesses
The text enumerates many "principal major illnesses": wind stroke, cold damage (shanghan), cold-fever alternating malaria, zhong'e (struck by evil influences), cholera-like disorders, massive abdominal edema, dysentery with pus and blood, difficulty in urination and defecation, ben-tun (running piglet syndrome), upward counterflow of qi, cough with counterflow, vomiting, jaundice, wasting-thirst (diabetes)., lingering fluid retention, food stagnation from dietary disharmony, hard accumulations, abdominal masses (zhengjia), fright illnesses, epilepsy, guizhu, throat blockage, tooth pain, deafness, blindness, metal wounds, fractures and sprains, abscesses, malignant sores, hemorrhoids and fistulas, goiter and tumors. In men: the five labors and seven impairments, deficiency, emaciation. In women: vaginal discharge, uterine bleeding, amenorrhea, and genital ulcers. Also injuries from worms, snakes, or gu poison. The text states these are "the overall general outlines," and that specific variations must be managed through detailed differential analysis.

🌿 Three Grades of Medicines and the Tendency Toward Immortality Beliefs
The text quotes works such as the Inner Chapters of Baopuzi, claiming that superior medicines bring bodily peace and extend life, even asserting the ability to "ascend to heaven as an immortal," "command all spirits," "instantly grow feathers," and "conjure a mobile kitchen at will." It states that middle medicines nourish one's nature, and lower medicines expel disease. It also claims the ability to ward off venomous insects and ferocious beasts and to dispel noxious qi and evil spirits. Master Taiyi is quoted as saying: "Superior medicines nourish life; middle medicines nourish nature; lower medicines nourish disease." These contents are clearly influenced by Taoist immortality philosophy and no longer belong wholly to the realm of medicine.

🌿 The Legend of Shennong Tasting Herbs
The text claims that Shennong used a red whip to examine all manner of herbs, stones, bones, and flesh among the ten thousand things, "questioning each by the whip," thereby learning their chief indications and five flavors, and that on a single day he encountered seventy poisons. This is clearly legendary in nature. Later annotations suggest that the "red whip" (zhebian) and "hook" might be borrowed characters for "boiling and distinguishing" (zhubian) and "testing and regulating" (houzhi), and that "questioning by the whip" may actually mean "distinguishing by inquiry"–a matter not necessarily to be regarded as inherently fantastic.

🌿 Records of Highly Toxic Medicines and Antidotes
The text lists several highly toxic substances, such as gouwen, owl (chi), Yinming, Neitong, and zhen feathers, stating that they must not enter the mouth, nose, ears, or eyes, or they will kill a person. It further records that five medicines—langdu, batou, lilu, tianxiong/aconite, and banmao—can be counteracted by zhan-si, huo-juice, lu-decoction, soybean, and Rong-salt, respectively. For toxic vegetables harming young children, human milk is used to counteract the poison; first administer two sheng of milk. These records merely reflect the ancients' awareness of poisoning risks and their early, limited experience with antidotes; they must not be used as a basis for modern poison management.

🌿 The Five Zhi and Mineral Medicines
The five zhi fungi, along with cinnabar, jade gelatin (yuzha), ores of hydrated copper carbonate (cengqin), realgar, orpiment, mica, and taiyi yu-yuliang (a type of limonite), were believed by the ancients to be suitable for solo ingestion, "enabling a person to fly and achieve longevity." Such claims belong to the exaggerated rhetoric of fangshi (esoteric masters) and immortality seekers and are not regarded as scientific fact in modern times.

🌿 Yin-Yang, the Four Seasons, Five Flavors, and the Five Elements
Spring and summer are yang; autumn and winter are yin. Spring is yang; yang is warm and gives life to the ten thousand things. Huangjing (Polygonatum) and cangzhu (Atractylodes), the ancients believed, could replace grain during famine, calling it "rice jerky." The five-flavor theory states: the sour flavor supplements the liver and nourishes the heart, while eliminating kidney disease; the bitter flavor supplements the heart and nourishes the spleen, while eliminating liver disease; the sweet flavor supplements the lungs/duly sphere and nourishes, while eliminating the roots of heart diseords; the pungent flavor supplements the lungs and nourishes the kidneys, while eliminating spleen complaints; and the salty flavor supplements the lungs/lungs large and curbs liver ailments. The five flavors correspond to the five elements, the four limbs to the four seasons. Since life corresponds with the four seasons and five elements, employing the mother to nourish the child may prolong the years, and holding the child to guard the mother may remove disease. Later annotations suggest that these materials originally belonged to the general introduction preceding the three grades (jade/mineral, vegetation, wood) sections, and were later excised or truncated.

🧠 Deep Understanding

Core Principles 💡

• Correspondence Between Heaven and Humanity: The total number of medicines, 365, corresponds to the 365 days of the year, reflecting the foundational worldview of Chinese medicine that "human beings correspond with heaven and earth."
• Ruler, Minister, Assistant, Courier: A prescription is not a crude accumulation of medicines but embodies a structure of primary and secondary roles, assistance, restraint, and harmonization.
• The Seven Combined-Use Relationships: Drug interactions are summarized as seven types, with particular emphasis on mutual reinforcement and mutual assistance as beneficial; mutual aversion and mutual opposition as unsuitable; and mutual fear and mutual killing as means to control toxicity. This is the core early theory of formula compatibility.
• The Four Natures and Five Flavors: The activity of a medicine is summarized through its nature and flavor, becoming the mainstay of Chinese medicinal property theory.
• Dosage Forms and Administration: Selecting pills, powders, decoctions, wines, or pastes—along with eating before or after administration, morning or evening dosing—reflects refinement in early clinical practice.
• View of Disease Progression and Prognosis: Emphasizes the importance of treating early "when the five viscera are not yet depleted, the six bowels not yet exhausted, the blood and vessels not yet disordered, and the spirit not yet scattered"—embodying a preventive treatment philosophy.
• Cautious Use of Toxic Medicines: Beginning with a very small dose and stopping when the disease subsides reflects dread of and caution regard to poisonous medicine, though the original dose escalation method should not be applied literally today.
• The Three-Grade Classification: The division into upper, middle, and lower medicines was likely based mainly on therapeutic intensity and toxicity but was later burdened by immortality-seeker additions of claims for ascension and longevity that fall outside medicine.

Modern Perspectives 🌟

• The correspondence of 365 medicines to 365 days is more of a cultural symbol and an effort toward systemic organization than an accurate statistical figure. The actual number of medicines far exceeds this.
• Ruler, minister, assistant, courier shares conceptual similarities with modern combination-therapy thinking regarding primary drug, adjuvant, corrective, and harmonizing agents. However, modern pharmacology emphasizes chemical components, molecular targets, and dose–response relationships, so the two cannot be fully equated.
• The seven combined-use relationships are empirical records of drug interactions. Mutual reinforcement and mutual assistance are similar to synergistic potentiation; mutual fear and mutual killing resemble toxicity reduction through combined use; mutual aversion and mutual opposition equate to antagonism or incompatibility. These provide reference value to modern studies, but require rigor in experimental verification.
• The four natures and five flavors are abstract generalizations in pharmacological theory. Some correspond to modern pharmacological activity, but many cannot achieve a direct alignment with chemical components and molecular mechanisms.
• Dosage-form selection embodies ancient pharmaceutics: water boiling for easy absorption, wine steeping to enhance dispersion, pills for sustained release, etc.—showing shared logical ground with sometimes more advanced ancient craft.
• Timing of administration relative to disease site reflects early chronopharmacological or dosing-scheduling thinking with some reasonable internal logic, yet each ancient rule must be individualized and validated through modern research; they are by no means universal standards.
• Starting toxic drugs at "a millet-grain size" suggests outwardly a modern approach to low-dose initiation followed by observation-based adjustments, but lacks standardization of dosage and legitimate toxicological monitoring, posing high risk under present standards. Modern individuals must never self-experiment. Today, one should always defer to professional care.
• The record of toxic medicines and antidotes shows true rigor regarding safety but many elaborate detox measures are layered with experience or folklore that remain unevaluated and sometimes dangerous.
• Claims of immortality, flying, commanding spirits, feathered metamorphosis, which instantly conjures mobility in the wilderness, are clear influences of Taoist esoterica and do not legally sit within the science-based domain of medicine.
• "Tasting a hundred herbs and encountering seventy poisons in one day" is a literary, mythological expression of ancestral narrative about the discovery of medicinal substances—a devoutly remembered oral heritage crafted through myth.

Health-Promoting Takeaways ⚡

• Prioritize prevention over cure. While the body has not noticeably declined and the spirit is uninjured, adopting regularity in lifestyle, plenty balanced emotions, prudent processing of them into reliable feeding is still more therapeutic than medicines after illness.
• Honor the cycle of the four seasons. Spending energy seasonally well—lively in spring-summer, more contained-autumn-winter—synchronizing normal daily rhythms generously benefits overall wellness.
• Eat moderately without risking undigestion or retention. Avoid binges; when discomfort arises, request correct consult; do not self-use whatever ancient appetite-testing medication has mystified.
• Beware of "miraculous elixirs." "Superior medicines” upon perfection claims lies outside factual medicine. Efficacious longevity inevitably requires solid consumption patterns rather than miracle substances including classic longevity hints of wonder or powder formulas.
• Never risk toxic medicine ad hoc. In all cases, potentially poisonous botanicals, and dosages likewise designed by original, verifiable toxin-bearing classics, requiring today’s appropriately licensed physician advocacy. For personal better health plain precautions among the modern detox-phobic vibe remain wholly valid without any home ingestion.
• Secure early detection and timely remedy. The ancient saw “achieving crie half-healed once matured Disease motion; illness passes barely-stand patient”—implies attending quickly the unwell helps everyone circumvent much needless loss of favor.
