Shennong Bencao Jing — Lower Volume
Overall Meaning (Paraphrase)
The Shennong Bencao Jing · Lower Volume states: the lower-grade drugs number one hundred and twenty-five in total, and in prescriptions they serve as adjuvant and guiding drugs (substances that assist or direct other medicinal forces to the site of disease). They are used chiefly to treat illness and correspond to the Earth aspect of yin-turbidity and corporeal form. Most of these drugs are toxic and cannot be taken long-term. Whenever one seeks to dispel cold-heat pathogenic qi (external or internally generated cold and heat pathogenic factors), attack and break up accumulations and masses (internal concretions, stagnations), or cure disease, one may rely on this Lower Volume.
The drugs of the Lower Volume are arranged by category as follows:
- Mineral and stone lower-grade: lime, alum stone, lead dan, powder tin, tin mirror knob, daizhe (hematite), lake salt, coarse salt, halogen salt, chalk, winter ash, green langgan (the original text notes: "the above minerals and stones, lower grade, eight kinds; in the old edition, twelve kinds").
- Herb lower-grade: fuzi (aconite root), wutou (aconite), tianxiong, banxia (pinellia), huzhang, yuanwei, dahuang (rhubarb), tingli, jiegeng (platycodon), langdangzi, caohao, xuanfuhua, lilu, gouwen, shergan (snake root), hehan (changshan), shuqi, gansui (kansui root), bailian, qingxiangzi, huojun, baiji, daji (large euphorbia), zeqi (sun spurge), yinyu, guanzhong, raohua, yazi, yangzhizhu, shanglu (poke root), yangti, bianxu, langdu (langdu root), bai touweng (Chinese anemone), guijiu, yangtao, nüqing, lianqiao, lüru (daphne), wujiu (spiderwort), luhuo, zaoxiu, shichangsheng, lujian, jincao, niubian, xiakucao (prunella), yuanhua (the original text notes: "the above herbs, lower grade, forty-nine kinds; in the old edition, forty-eight kinds").
- Wood lower-grade: badou (croton), shujiao (prickly ash), zaojia (gleditsia), liuhua, dongshi, yuliren (bush cherry seed), mangcao (illegal), leiyuan, tongye (paulownia leaf), zibaipi (catalpa bark), shinan, huanghuan, xishu, shuli (buckthorn), xiaoshiyao gen, luanhua, manjiao (the original text notes: "the above woods, lower grade, seventeen kinds; in the old edition, eighteen kinds").
- Animal lower-grade: tunluan (pig's testis), mizhi (deer fat), shu (rat), liu chu mao tijia (the hair, hoof, and horn sheath of the six domestic animals) (the original text notes: "the above animals, lower grade, four kinds; the old edition is the same").
- Insect and fish lower-grade: hamou (toad), machen (mussel shell), (snake slough), qiuying (earthworm), xianweng (wasps), wugong (centipede), shuizhi (leech), banmiao (cantharides), beizi (cowrie shell), shichan, queweng (mantis egg case), qianglang (dung beetle), lougu (mole cricket), malu (millipede), didan (ground beetle), shufu (slater), yinghuo (firefly), yiyu (silverfish) (the original text notes: "the above insects and fish, lower grade, nineteen kinds; the old edition had eighteen kinds").
- Another two wood lower-grade: taoberren (peach kernel), xingheren (apricot kernel).
- Grain lower-grade: fabi (a medicinal "rotten bean" preparation).
- Vegetable lower-grade: kuhu (bitter gourd), shuijin (water dropwort).
- One unclassified: bizi.
These are the drug names recorded in the Lower Volume. It is worth noting that the preface claims "one hundred and twenty-five lower drugs," but discrepancies exist in the recorded numerical categories of the transmitted editions—these are textual variations inherent in the ancient manuscript tradition.
🧠 Deeper Understanding
Core Principles 💡
This passage centrally reflects the Three-Grade Classification idea of the Shennong Bencao Jing:
- Upper grade corresponds to Heaven: mostly nontoxic, serves to nourish life and prolong years; Middle grade corresponds to Human: partly toxic, partly not, serves to nourish one's nature; Lower grade corresponds to Earth: mostly toxic, used to attack disease and expel pathogenic factors.
- The positioning of lower-grade drugs as "adjuvant guides" indicates that within a formula they do not assume the primary role of supplementing and supporting right qi. Instead, with their constitutionally "biased and toxic" nature-of-extremes, it is by virtue of using bias to counteract bias that they expel pathogenic factors.
- The phrase "most are toxic and cannot be taken long-term" constitutes the fundamental safety principle for lower-grade drugs. The ancients realized that such medicinals are fierce in action and can only be employed for short durations to dispel cold-heat pathogenic qi or break up accumulations and masses, and they should never be taken as daily care or tonic.
- The statement "for treating disease, responding to Earth" implies that these drugs chiefly act on corporeal, deeply rooted, yin-turbid pathological products such as stuck stagnation, masses, phlegm-rheum, and static blood—taking hold naturally of the imagery of "Earth"—sinking, contracting, and having manageable physical presence.
Modern Understanding 🌟
From a modern pharmacological perspective, the lower-grade list indeed contains many species with intense biological activity and plainly demonstrable toxicity:
- Aconitum species (wutou, fuzi, tianxiong) contain aconitine alkaloids, which exhibit analgesic and cardiotonic-like effects, yet have an extremely narrow therapeutic window; excess can produce arrhythmia or even death;
- Croton (badou) contains croton oil with strong purgative action, markedly irritating to mucous membranes;
- Cantharis (banmao) contains cantharidin, which possesses great irritant effect and has been studied for antitumor activity in modern trials, though with major liver and kidney toxicity;
- Leech (shuizhi), centipede (wugong), and other insect drugs carry multiple enzymes and peptides, and extensive modern research describes potential anticoagulant and anti-inflammatory activity.
The ancients classifying them as "poisonous, not to be taken long-term" generally aligns with the modern toxicological view of "narrow therapeutic index requiring strict observance of dose and duration." However, one must also note that the ancient classificatory schema—its "Earth-response" designations, and "dispeling pathogenic qì," etc., rests most fundamentally on holistic image-numerical thinking; this is not a taxonomy of pharmacology. Even specific drug names, origins, and concepts as "accumulations and masses" or "cold-heat pathogenic qi" cannot have direct equivalence with modern diseases.* Hence, where accepted materials must necessarily remain open to, they can and should be interpreted rationally and historically.
Insights for Health Maintenance ⚡
- The lower-volume warning: "多毒，不可久服" is still a basic—indeed vital—safety precept: any drug with strong medicinal properties or marked toxicity must be under professional physician control, and must not be self-collected, made into alcoholic tinctures, taken for extended periods, or treated as a health supplement.
- Far better daily maintenance resides in **nourishing / strengthening proper qi and a healthy systemic state—regular eating habits, normal daily rhythms and a structured way-of-life, and not spending energy through imposition—while minimizing the bodily conditions (internally AND externally) for accumulation of pathological, static materials and the internal & >-kind or any-vicious-force irritations to arise.
