Shennong Ben Cao Jing (The Divine Farmer's Materia Medica) — The Lower Classics
Overall Paraphrase
The Shennong Ben Cao Jing · Lower Classics states: There are 125 kinds of lower-grade medicinals. In formulae they serve as assistant and guiding agents (medicinals that assist and direct the medicinal power to the site of disease), mainly used for treating disease. They correspond to the muddy, turbid, and corporeal nature of Earth. Most of these medicinals are toxic and cannot be taken long-term. Whatever involves dispelling the cold and heat evils (externally contracted or internally generated cold/heat pathogenic influences), attacking and breaking up accumulations and conglomerations (internal masses and stagnant concretions), and curing disease may be effectively pursued in accordance with this Lower Classics.
The lower-grade medicinals are arranged by category as follows:
- Jade/Stone Lower Grade: lime (calcium carbonate), alunite, lead dan (red lead), tin powder (lead powder), tin mirror nose, daizhe (red ochre), rongyan (halite), dayan (coarse salt), luyan (bittern salt), bai'e (white chalk), donghui (winter ashes), qinglanggan (green jadeite). (Original text notes: "These jade and stone [items], eight kinds in the lower grade; in the old edition, twelve kinds.")
- Herb Lower Grade: fuzi (aconite lateral root), wutou (aconite root), tianxiong (aconite crown), banxia (pinellia), huzhang, yuanwei (iris), dahuang (rhubarb), tingli (lepidium seed), jiegeng (platycodon), langdangzi (henbane seed), caohao (Artemisia annua), xuanfuhua (Inula flower), lilu (veratrum), gouwen (gelsemium), shegan (belamcanda), shehe (withdrawn), hengshan (dichroa), shuqi (dichroa branchlet), gansui (kansui root), bailian (Ampelopsis), qingxiangzi (Celosia seed), huojun (bracket fungus), baiji (Bletilla), daji (Euphorbia pekinensis), zeqi (Euphorbia helioscopia), yinyu (Skimmia), guanzhong (Cyrtomium rhizome), yaohua (Wikstroemia flower), yazi (Daphne genkwa root), yangzhizhu (Rhododendron molle), shanglu (Phytolacca), yangti (Rumex), bianxu (Polygonum aviculare), langdu (Euphorbia fischeriana), bai tou weng (Pulsatilla), guijiu (Dysosma), yangtao (Actinidia), nüqing (Metaplexis), lianqiao (Forsythia), lüru (Euphorbia lathyris), wujiu, luhuo, zaoxiu (Paris polyphylla), shichangsheng (Selaginella), luying (Sambucus chinensis), jincao (Arthraxon), niubian, xiakucao (Prunella), yuanhua (Daphne genkwa). (Original text notes: "These herbs, forty-nine kinds in the lower grade; in the old edition, forty-eight kinds.")
- Wood Lower Grade: badou (croton seed), shujiao (Zanthoxylum fruit), zaojia (Gleditsia spine/fruit), liuhua (willow flower), dongshi (Melia fruit), yuliren (Prunus japonica seed), mangcao (Illicium leaf), leiwant (Omphalia), tongye (Paulownia leaf), zibaipi (Catalpa bark), shinan (Photinia), huanghuan (liana), soushuh (Deutzia), shuli (Rhamnus), yaoshigen (Medicinal root), luanhua (Koelreuteria flower), manjiao (Zanthoxylum). (Original text notes: "These wood [items], seventeen kinds in the lower grade; in the old edition, eighteen kinds.")
- Animal Lower Grade: tunluan (pig testicle), mijuzhi (elk fat), shu (rat), liuchu mao ti jia (domestic animal hair, hoof and nail). (Original text notes: "These animals, four kinds in the lower grade; same in the old edition.")
- Insect/Fish Lower Grade: hama (toad), madap (razor clam), shetui (snake slough), qiuyin (earthworm), yaweng (wasp larva), wugong (centipede), shuizhi (leech), banmao (blister beetle), beizi (cowrie shell), shican (caddisfly), queweng (mantis egg case), qielang (dung beetle), louluoke (mole cricket), malu (millipede), didan (mylabris), shrub (mouse louse), yinghuo (firefly), yiyu (silverfish/bookworm). (Original text notes: "These insects and fishes, nineteen kinds in the lower grade; in the old edition, eighteen kinds.")
- Wood Lower Grade — two further kinds: taohao (peach kernel), xinghao (apricot kernel).
- Grain Lower Grade: fufei.
- Vegetable Lower Grade: kuhu (bitter gourd), shuijin (water dropwort).
- One unidentified: bizi.
The above is the list of lower-grade medical names in the Lower Classics. Note well that the preface states “one hundred and twenty-five lower medicinals,” yet discrepancies exist in the transmitted numbers classified — such differences are the result of textual variation in ancient manuscripts.
🧠 Deeper Understanding
Core Principles 💡
This passage embodies the Three-Grade Classification System of the Shennong Ben Cao Jing:
- Upper grade corresponds to Heaven: mostly non-toxic, chiefly restores life and prolongs years; Middle grade corresponds to Man: growing with toxicity varied in equal measure, and chiefly nourishes vital nature. Lower grade corresponds to Earth: largely toxic, mainly attack afflictions and eliminate heteropathic forces.
- Lower-grade medicinals are positioned as "assistant agent(s)"; meaning that in a formula they do not take the primary role of replenishing vital-interior and strengthening authentic qi. Rather, they act through their partisan and sometimes toxic nature — using partisan corrected by corrective — to attack/drive illnesses.
- The line "most are toxic and cannot be taken long-term" is a fundamental principle of the use of these lower-grade medicinal medicines. The ancients recognized that the force of these pharmacological preparations was vigorous and that they could only be used on a provisional basis to remove cold and heat heteropathy, and to break accumulation — they were never to be taken as ordinary tonics.
- The line "treat disease in correspondence with Earth" also implies that lower-grade formulary materials act with greatest effect on the corporeal, deep seated and Yin-turbid pathological products of the human body — such as retained lumps, coagulations, phlegm-yin and stagnated blood. Taking Earth's significance herein stands for descending, constricting and corporeal.
Modern Understanding 🌟
From a modern pharmacological perspective, lower-grade medicinals do indeed include dozens of species that have strong bioactivity, along when broad degrees of toxicity:
- Fuzi, Wutou, and Tianxiong contain aconitine with analog-manifest effects resembling analgesia and cardiotonic properties, but their therapeutic index is extremely narrow; at excess doses they can produce arrhythmias or even fatalotoxicity.
- Badou (croton seed) contains croton oil, characterized by dramatic, mucosa-irritant and cathartic activity;
- Banmao (blister beetle) contains cantharidin for serious irritant effects; modern research on individual directions has also studied its antitumor activity, though hepato- and nephro-toxicity are clear;
- Alternatives (shuizhi – leech; wugong – centipede) carry numerous enzymes and peptides whose activity patterns — drawn from modern study — reveal anticoagulation and anti-inflammatory potentials, among others.
The ancients divided them into "most are toxic and interfere if chronic" (poisonous and cannot be suitably taken on prolonged advice), most importantly reconciling the perspective of modern toxicology within "a narrow therapeutic index: adequately dosing and scrupulous period limitations". Those ancient categories—"matching to the visual imagery of the Earth" and theory establishing these medically listed elements due to treatment across types of conceptual diseases—stand distinct from today's pharmacologic divisions. Facts in everyday diagnostics— precise medical correspondence to this age level explanations of all the principles it provides etc— correspond as direct guides, so accordingly the need to preserve a rational, appreciative if historical, identification using distance assessment is necessary.
