【无毒】附：粗纹理黄石、水中圆石。土石类生。
姜石主治热毒豌豆疮、疔毒等引起的肿胀（名医所录）。【产地】《图经本草》记载：产于土石之间，以齐州历城县出产的为优良，各地也有出产。现在只有齐州出产。其形状像生姜，有五种。凡入药以白色、质地疏松而不粗糙者为好。又有粗纹理的黄石和水中圆石，多用于治疗痈疽疮肿，然而它们各有疗效，所以一并附录于此。《衍义本草》记载：姜石到处都有，必须是不见日色、刚采挖出来呈微白色的为佳。【采集时间】随时可采。【药用标准】以白色、质地疏松而不粗糙者为佳。【颜色】白色。【味道】咸。【性质】寒，质软。【气味】气味浓厚，属阴。【气味特征】腐朽味。【主治】疔肿、痈疽。【炮制方法】研成细粉使用。【治疗方剂】《别录》记载：水中圆石治疗背上突然肿胀，逐渐扩大如碟子大小，不知病名的情况。取一两碗该石烧至极热，投入清水中，待沸腾停止后，用此水洗患处，立即可愈。【配伍治疗】将白姜石粉末与鸡蛋清混合，敷于疔肿处，疔毒自然排出；涂抹于乳痈也效果很好。○粗纹理黄石如鹅卵大小，用猛火烧烤至通红，频繁地浸入浓醋中，直到石块完全淬炼尽，取出碎屑晒干，捣碎过筛，调和醋液涂抹于背疮，立即痊愈。
麦饭石治疗发背等各类痈疽，神效（名医所录）。【产地】《图经本草》记载：这种石头粗糙，黄白色类似麦饭，曾经用作磨盘的尤其好。但我考证陈自明的说法，认为麦饭石不可作磨盘，古语说“作磨者尤佳”，恐怕是迷惑人。大概是因为这种石头形状像饭团，表面有颗粒点罢了。如果没有这种石头，可以用旧面磨靠近齿部的石头代替，取其具有麦性的缘故。多次试验都有效。这种石头在市面上有时也买不到。如果想用，只要在溪水中寻找麻石中有白石肌粒如豆米大小的即是。但这种石头大小不同，有的如拳头大，有的如鹅卵大，有的如盏大，大致就像握聚一团麦饭一样。【采集时间】随时可采。【质地】类似麦饭团。【颜色】黄白色。【气味特征】腐朽味。【炮制方法】不限数量，用炭火烧至通红，用优质浓米醋淬炼。如此反复淬炼十次，然后碾成粉末，重新筛选去掉粗渣，取细末放入乳钵内，由数人轮流研磨五到七天，要磨得像面粉样极细才好。如果不细，涂抹在疮上会极其疼痛难忍。【配伍治疗】取细末二两，配合生取的鹿角一具（连脑骨完整），截成二三寸长，用炭火烧至烟尽为度，碾罗成粉末，再放入乳钵中研令极细。将四两鹿角末与二两白蔹末三物混合，用三年好米醋放入银石器中煎煮，至出现鱼眼泡时，缓缓加入前面的药末，用竹篦子不停手搅拌熬煮一两个时辰，使稀稠适度。取出倒在瓷盆内，冷却后用纸盖住，不要沾染尘埃。每次使用时，先用猪蹄汤洗净疮上的脓血至干净，用旧布吸干，用鹅翎蘸药膏涂抹四周。凡是发红处都涂满，只留中心一个如铜钱大的孔以排出脓血，使热毒之气随脓血排出。如果脓未溃破，能使之内消；如果已溃破，则能排脓如湍水般迅速。每日可见疮口收敛。如果患疮日久，肌肉腐烂，筋骨露出，用旧布片涂上药贴于疮上，只要膈膜不穿孔也能取得安宁。洗疮时不要用手触动嫩肉，也不可以用口气吹着疮，更忌讳有腋臭的人及月经来潮的妇人或有孕妇参与制药。【替代】如果没有这种石头，取旧面磨靠近齿部的石头代替。
[Non-toxic] Appendix: Yellow stones with coarse texture, round stones from water. Born in earth and stone.
Jiangshi (Ginger Stone) treats swelling caused by heat-toxin pea sores, Ding toxic carbuncles, etc. (Recorded by famous physicians). [Origin] *Tujing Bencao* states: Grows among earth and stones; those from Licheng County, Qizhou are superior, though available elsewhere. Currently, only Qizhou produces them. Their shape resembles ginger, with five varieties. For medicinal use, white ones that are friable but not gritty (Cha Ren qie) are preferred. There are also yellow stones with coarse texture and round stones from water, which mostly treat yong abscesses and sore swellings. However, each has its own efficacy, so they are appended together. *Yanyi Bencao* states: Jiangshi is found everywhere; those not exposed to sunlight and freshly dug with a slightly white color are best. [Harvest Time] Anytime. [Medicinal Standard] White, friable, and non-gritty are best. [Color] White. [Flavor] Salty. [Nature] Cold, soft. [Qi and Flavor] Strong flavor, Yin nature. [Odor] Rotten. [Indications] Ding swellings, yong abscesses. [Processing] Grind into fine powder for use. [Treatment Formula] *Bielu* records: Round stones from water treat sudden swelling on the back that gradually expands to the size of a saucer, of unknown name. Take one or two bowls of this stone, burn until extremely hot, immerse in clear water. After boiling stops, wash the swollen area with this water; it heals immediately. [Compound Treatment] Mix Bai Jiangshi (White Ginger Stone) powder with egg white, apply to Ding swellings; the toxin will naturally emerge. Applying to Ru Yong (Breast Abscess) is also effective. ○ Coarse-textured yellow stones, the size of goose eggs, are fiercely burned until red-hot, frequently quenched in strong vinegar until the stone is fully processed. Take the residue, dry in sun, grind and sieve, mix with vinegar, and apply to back sores; it heals immediately.
Maifanshi (Wheat-Rice Stone) treats Fa Bei (Back Carbuncle) and various other yong abscesses with divine efficacy (Recorded by famous physicians). [Origin] *Tujing Bencao* states: The stone is rough, yellowish-white, resembling wheat-rice; those previously used as millstones are especially good. However, I verify Chen Ziming's claim that Maifanshi should not be used as a millstone. The ancient saying "those used as mills are best" may be misleading. It is likely because the stone resembles rice balls with granular spots. If this stone is unavailable, old millstones near the teeth of flour mills can substitute, taking advantage of their wheat-like properties. Repeated trials show effectiveness. This stone is sometimes not sold in markets. To obtain it, search in streams for gray stones containing white mineral grains the size of bean rice. These stones vary in size: some fist-sized, some goose-egg sized, some cup-sized, roughly resembling a handful of wheat-rice. [Harvest Time] Anytime. [Texture] Resembles wheat-rice balls. [Color] Yellowish-white. [Odor] Rotten. [Processing] No limit on quantity. Burn with charcoal fire until red-hot, quench in good strong rice vinegar. Repeat quenching ten times, then grind into powder. Sieve again to remove coarse particles, take the fine powder, place in a mortar, and have several people take turns grinding for five to seven days until extremely fine like flour. If not fine enough, application to sores causes unbearable pain. [Compound Treatment] Take two liang of fine powder, combine with one fresh Lu Jiao (Deer Antler), including the whole brain bone, cut into 2-3 cun lengths. Burn with charcoal until smoke ceases, grind and sieve into powder, then grind in mortar until extremely fine. Mix four liang of Deer Antler powder with two liang of Bai Lian (Mallow Root) powder. Add three years' aged good rice vinegar to a silver or ceramic vessel, boil until fish-eye bubbles appear. Slowly add the previous powder mixture, stir constantly with a bamboo spatula for one to two hours until the consistency is appropriate. Pour into a porcelain basin, let cool, cover with paper to prevent dust contamination. When using, first wash the pus and blood from the yong sore clean with pig trotter soup, dry with an old cloth. Dip a goose feather in the ointment and apply around the perimeter. Cover all red areas, leaving only a central hole the size of a coin to drain pus and blood, allowing heat-toxin qi to exit. If the pus has not ruptured, it promotes internal resolution; if already ruptured, it drains pus rapidly like swift water. Daily observation shows wound contraction. If the sore is chronic with rotting flesh and exposed bones/tendons, apply the medicine-soaked old cloth to the sore; even without perforating the membrane, it brings relief. Do not touch tender flesh with hands when washing, do not blow breath on the sore, and avoid participation by individuals with axillary odor, menstruating women, or pregnant women during preparation. [Substitute] If this stone is unavailable, substitute with old millstones near the teeth of flour mills.
