予今选集名方,以防疾苦,然博文之士,不在具陈,行路之间亦虑遗忘,今略书其修合
节度,列之如右。
凡药有酸碱甘辛苦之五味,寒热温凉四气,有毒、无毒、阴干、曝干,收采各顺岁时,
新陈别其真假,凡将修合,并须精细。
凡药有分剂斤两,轻重多少,不可妄有增减,若用得其宜,与病相会,入口必愈。
凡药有宜丸者,宜服散者,宜水煮者,宜酒渍者,亦有不可入汤酒,不可犯火气,并如
本法,不可改易。
凡捣罗药竟,恐有铁屑,以好磁石搅 取之。
凡病在胸膈以上者,先食后服药,病在心腹以下者,先服药后食,在四肢血脉者,宜空
心服,在骨髓者宜饱满临卧,并依本法,次第服之。
凡药须要酒服者,以助其势,饮服者直攻其疾,有冷有暖,有疏有数,并有本方,不可
妄服。
凡药须去苗去核,有燥有湿,将欲杵合,再秤取合足,分两或差,应病必误。
凡筛散药竟,即须再罗,贵其匀细。
凡和合丸药成团,必须再杵千百下,视其色和同,亦须易为丸KT 。
凡云蜜剂,取药末分两算,乃蒸炼其蜜合和,滋润,全胜火熬法用生蜜自如本方。
凡蒸药,常用微火煎令小沸,用水多少,煎及分数,并依本方。
凡修合,本方自有修制,切在依禀,不可更变。
凡药有三品,禀性不同,攻病既除,不必尽剂。
凡服药有先有后,有早有晏,盖相须而相使,或相反而相制,但从本方,不宜更易。
I have now selected and collected famous prescriptions to prevent diseases and alleviate suffering. However, scholars with extensive knowledge need not have everything detailed here; fearing forgetfulness during travel, I now briefly record the regulations for processing and compounding them, listed as follows.
All medicines possess five flavors: sour (Suan), bitter (Ku), sweet (Gan), pungent (Xin), and salty (Xian) [Note: Text says "acid/alkali" but context implies Five Flavors], and four qi properties: cold (Han), hot (Re), warm (Wen), and cool (Liang). Some are toxic (You Du), some non-toxic (Wu Du); some are dried in shade (Yin Gan), some sun-dried (Pu Gan). Harvesting must follow the seasons, distinguishing between new and old, authentic and fake. All processing and compounding must be meticulous.
All medicines have specific dosages and weights. The lightness or heaviness, quantity or scarcity, must not be arbitrarily increased or decreased. If used appropriately and matching the disease condition, ingestion will surely lead to recovery.
Some medicines are suitable for pills (Wan), some for powders (San), some for water decoction (Shui Zhu), some for wine maceration (Jiu Zi). Others are unsuitable for decoctions or wines, or must not contact fire heat. These must follow the original methods and cannot be altered.
After grinding and sifting medicines, iron filings may remain. Use high-quality lodestone (Ci Shi) to stir and attract them out.
For diseases located above the chest and diaphragm (Xiong Ge), take medicine after meals. For diseases below the heart and abdomen (Xin Fu), take medicine before meals. For diseases in the limbs and blood vessels (Zhi Mai), take on an empty stomach. For diseases in the bone marrow (Gu Sui), take when full, just before sleep. Follow these rules sequentially.
When medicines require administration with wine, it is to assist their potency. Administration with water directly attacks the disease. Dosage intervals vary from sparse to frequent, depending on whether the nature is cold or warm. All follow the specific prescription; do not administer arbitrarily.
Medicines requiring removal of roots/stems (Miao) or pits/kernels (He) vary in dryness or moisture. Before pounding and mixing, re-weigh to ensure exact proportions. Any deviation in weight will inevitably lead to treatment failure.
After sifting powdered medicines, sift again to ensure uniformity and fineness.
After forming pill masses, pound them thousands of times until the color is uniform, ensuring they are easy to shape into pills.
For honey-based preparations (Mi Ji), calculate the proportion of medicinal powder, then steam and refine the honey before mixing. This moistens the mixture. Its efficacy surpasses that of fire-roasted methods; using raw honey naturally follows the prescription.
For steaming medicines, use low heat to bring to a gentle boil. The amount of water and duration of boiling must follow the prescription.
In all compounding, if the prescription specifies processing methods, strictly adhere to them without alteration.
Medicines are classified into three grades (San Pin) with different inherent natures. Once the disease is eradicated, it is not necessary to consume the entire dose.
The timing of medication (early vs. late, first vs. last) depends on mutual assistance (Xiang Xu) and facilitation (Xiang Shi), or opposition and restraint (Xiang Fan / Xiang Zhi). Always follow the prescription; do not change easily.
