Shennong's Classic of the Materia Medica
The Middle Classic of Shennong's Classic of the Materia Medica
Overall Paraphrase
Shennong's Classic of the Materia Medica classifies medicines into three grades: upper, middle, and lower. The Middle Classic (middle grade) records a total of one hundred and twenty medicines, which occupy the position of "minister" in formula compatibility (assisting the sovereign medicine and enhancing its therapeutic effects). Their primary function is nourishing one's nature (regulating life vitality and supporting the body's upright qi), corresponding to the level of "human beings."
The characteristic of middle-grade medicines is that they include both toxic and non-toxic substances, and their use requires careful consideration of appropriateness — weighing and deciding based on the deficiency or excess of the condition, the strength or weakness of the constitution, and the intensity or mildness of the medicinal properties. The core purposes of middle-grade medicines lie in curbing disease (checking the progression of illness) and replenishing weakness (rehabilitating deficiency and emaciation), i.e., combining attack and supplementation while addressing both the root and the branch.
The original text then proceeds by listing the names of middle-grade medicines according to eight categories: mineral, herb, wood, beast, fowl, insect/fish, fruit, and grain:
- Middle-grade minerals (14 kinds): Realgar, Sulfur, Orpiment, Mercury, Gypsum, Magnetite, Mirabilite (Glauber's salt), Actinolite, Stalactite (stitactite), Stalactite (concretion), Iron filings, Limonite (Lishi), Feldspar (Long stone), Mica (skin-green).
- Middle-grade herbs (49 kinds): Dried ginger, Cocklebur fruit, Pueraria root, Trichosanthes root, Sophora flavescens, Chinese angelica, Ephedra, Rice-paper plant pith (Tetrapanax), Peony root, Blackberry lily seed (Iris seed), Dianthus herb, Scrophularia root, Gentiana macrophylla, Lily bulb, Anemarrhena rhizome, Fritillaria bulb, Angelica dahurica root, Epimedium, Scutellaria root, Cibotium rhizome, Ranunculus sceleratus, Imperata root (white cogongrass rhizome), Aster root, Lithospermum root, Patrinia herb, Dictamnus bark, Physalis (winter cherry root), Purple salvia root, Chinese lovage (Ligusticum sinense), Pyrrosia leaf, Dioscorea hypoglauca rhizome, Cynanchum atratum root, Duckweed, Trichosanthes cucumber (Wang gua), Sanguisorba root, Seaweed, Lycopus herb, Stephania root, Coltsfoot flower, Moutan bark, Pedicularis herb, Centella asiatica, Conyza root (female aster of another kind), Bishop's weed (Wang sun), Solanum lyratum, Brrard rock cress (Clinopodium), Schizonepeta, and Tinospora root.
- Middle-grade woods (17 kinds): Mulberry root bark, Bamboo leaves, Evodia fruit, Gardenia fruit, Elm seed paste (ulmus preparation), Immature bitter orange, Magnolia bark, Ash bark, Zanthoxylum (Sichuan pepper), Cornus fruit, Campsis flower (trumpet creeper), Polyporus umbellatus, White spine jujube (white thorn), Longan fruit, Usnea (old man's beard), Euonymus (winged spindle tree), and Albizia (silk tree) bark.
- Middle-grade beasts (7 kinds): Horse penis (stalks), Deer antler, Buffalo horn (sacrum), Ram's horn, Dog penis (male dog genitalia), Antelope horn, and Rhinoceros horn.
- Middle-grade fowl (2 kinds): Swallow droppings and Bat droppings (bat guano).
- Middle-grade insects/fish (17 kinds): Hedgehog skin, Wasp nest (polistes nest), Turtle shell, Crab, Cicada slough (nymphal exuviae), Grub (white grub), Cuttlefish bone (cuttlebone), White silkworm, Snake slough (snake skin shell), Tettigonia (cicada), Garden slug (limax), Skink (石龙子), Horsefly (Tabanus), Gadfly (chrysops), Blister beetle (Mylabris), Ground beetle (Eupolyphaga), and Bat (vampire bat).
Note: The original texts lists four items for grains while claiming three; this may be a transcription error, so the count is four and the correctness is questionable.
- Middle-grade fruits (1 kind): Dark plum (Mume fruit).
- Middle-grade grains (3 kinds): Soybean sprout, Red adzuki bean, Foxtail millet, and Broomcorn millet.
Overall, the position of middle-grade medicines lies between "upper-grade nourishing life" and "lower-grade treating disease," and is characterized by a combination of attacking and supplementing while being nourishing but simultaneously therapeutic — the mainstay of clinical treatment in Chinese medicine. 🌿
🧠 Deep Understanding
Core Principle 💡
"Middle grade serves as the minister, primarily nourishing one's nature to respond to humans" is one of the core concepts in the three-grade classification system of Shennong's Classic of the Materia Medica. This classification system establishes a "Heaven—Human—Earth" energetic correspondence hierarchy for medicines:
- Upper grade (120 kinds) are "sovereigns," primarily nourishing life and responding to Heaven; most are non-toxic and suitable for long-term use, such as ginseng, licorice, and rehmannia.
- Middle grade (120 kinds) are "ministers," primarily nourishing one's nature and responding to Humans; they include both toxic and non-toxic substances and require careful selection.
- Lower grade (125 kinds) serve as "assistants and couriers," primarily treating diseases and responding to Earth; many of them are toxic and not suitable for prolonged use.
"Nourishing one's nature" differs from the purely supplementary nature of "nourishing life" and the harsh pathogenic-clearing nature of "treating disease." "Nature" refers to the state of vital activity and inherent constitution of an individual — the core function of middle-grade medicines lies in adjusting imbalances and excesses of the body, bringing the dysfunctional state back to the mean of regulation. The expression "curbing disease and replenishing weakness" reveals the dual function of middle-grade medicines: they can both check the pathogens (eliminate pathogenic factors) and replenish deficiency and damage (support the righteous qi), placing them at the intermediate realm of "attacking and supplementing concurrently."
This classification concept also implies the principle of sovereign, minister, assistant, and courier in formula construction: middle-grade drugs typically serve the role of "minister," assisting the sovereign, enhancing the efficacy, and addressing secondary symptoms. For example, in Ephedra Decoction (Mahuang Tang), Ephedra is the sovereign (for inducing sweating and releasing the exterior), Cinnamon twig is the minister (assisting Ephedra in inducing sweating), and Almond and Licorice serve as assistant and courier respectively (for descending lung qi) — being designated as minister in the classic coincides appropriately.
Furthermore, the phrase "containing both toxic and non-toxic kinds, employ with suitable caution," reflects the rudimentary awareness regarding safety classification of drug substances in the Classic. Middle-grade drugs encompass those with mild toxicity and even highly poisonous preparations (such as mercury, realgar, and evodia), and also those completely nontoxic (such as kudzu root, lily bulb, and longan fruit). Their administration must discriminate accurately between cases, measure and accommodate different proportions — treated on a case-by-case foundation. This notion of "ponder appropriately" presents the rudimentary spirit of syndrome-differentiated treatment on the pharmacological battlefield in an early form of Chinese medicine.
Modern Understanding 🌟
From a modern pharmacognostic perspective, the categorization of middle-grade drugs in Shennong's Classic of Materia Medica carries considerable and rational underpinnings, yet bears its share of historical constraints.
Aspects of validity: Many of the listed middle-grade drugs remain clinically-applied and one observes the apparent duality of "attacking and supplementing simultaneously." For example:
- Dang gui: Nourishes the blood while invigorating it, quintessentially a “supplement with movement”.
- Pueraria root: releases muscle tension and clears heat (eliminating pathogens), at the same time regenerating fluids and raising the clear yang (tonifying righteous energy).
- Cortex magnoliae officinalis: functional in modulating qi and drying dampness (eliminating pathogenic factors) while bringing bidirectional regulatory actions on the GI tract.
- Deer antler: warmly tonifies kidney yang (supporting vital correct qi), though properties are relatively warm and dessicating; ingested in surplus can easily induce blood-flow—demanding ponder.
Historical limitations:
- Certain inclusions obviously echo limited primitive cognition for their date. Mercury was classified among intermediaries, whereas the contemporary medicinal sciences confirm its explicit neurotoxicity and nephrotoxicity, making unsafe beyond informed manipulation; realgar is likewise by nature an ore infused arsenic.
- Pigeon droppings and bar common bat excrescences, simultaneously with grub worms grown for its alleged health—those exotic treatments from longstanding tradition see as few only infrequently applied future plausibly within modern medic science. Equally does bat placement in the insect-fish class underline the old-fashioned animal taxonomic framework,
- Also among Equus stalk or “male bitch” canine glans whose pharmacotherapeutic (embeddings in the ancient syncc – matching and form-alignment paradigm) may be conventionally argued, their specific impact now barely obtains pharmacological vindication.
