（凡疮发于秋冬为逆当纯阴之时也）
足胫冷 腹虚胀 粪青色 面 白 呕乳食 目睛青 脉沉微
以上七证，不
宜服寒药。
痘疮盛出，四肢逆冷或自利，系在太阴脾经，宜急温之，用异功散（出不快）、附子
理中汤（泻）、调中丸（泻）。痘疮平塌，灰白色不泽，此是正气不足，宜十补托里散，倍
黄、加熟附子。或四肢厥冷，时作搐搦，系在厥阴，宜温之异功散（出不快）加防
风、青皮，或白术散（渴）去干葛、藿香，加附子、肉桂。
痘疮证，有阳盛阴虚，有阴盛阳虚，阳盛者饮冰雪不知寒，阴盛者饮沸汤不
知热。凡发热作渴，手足逆冷，大便自利，喜饮热汤，皆阴盛阳虚也，薛氏用大
异功散（出不快）、八味丸治之。若发热作渴，而大便秘结，手足并热，喜饮冷水，皆
阳盛阴虚也，薛氏用四顺饮（热）、地黄丸（肾）、治之。若烦热作渴，面赤睛白，此为肾经
虚热，亦宜地黄丸之类。陈文中治阴盛阳虚用大异功散加木香、当归、以补阳是
矣，治阳盛阴虚，用木香散加丁香、官桂、以补阴，不为以火济火乎，此陈氏方
所以为一偏之术，而见讥于前哲也。学人不察，而误用之，夭枉可胜道哉。
凡疮疹已出后有声音者，乃形病而气不病也，身温者宜解毒防风汤（大法），大便闭
者宜当归丸（便秘）。疮疹未出，先声音不出者，乃形不病而气病也，宜补肺散（失音）加生
黄。若疮疹出而声音不出者，是形气俱病也，小儿禀赋素弱者宜预服十奇散（即
十宣散见起发）倍归、芎、少木香煎服。（或云，宜十补散，或大异功散，或云形气俱病者、当
清其肺，宜八风汤，并凉膈散去硝黄主之。）
(Whenever sores or rashes erupt in autumn and winter, it is considered a counterproductive pattern, as this period corresponds to the time of pure Yin.)
Coldness in the lower legs and shins, abdominal distension with deficiency, green-colored stool, pale complexion, vomiting of milk and food, bluish-green sclera, and a deep and faint pulse.
For the above seven signs, cold-natured medicines should not be administered.
When pustular eruptions are abundant and emerging, if there is coldness of the four limbs or spontaneous diarrhea, the pathogen is located in the Taiyin Spleen Meridian; urgent warming is required. Use Yigong San (for slow eruption), Fuzi Lizhong Tang, or Tiaozhong Wan (for diarrhea). If the eruptions are flat and sunken, grayish-white and lusterless, this indicates insufficiency of righteous Qi; Shibu Tuoli San should be used, with doubled Huangqi (Astragali Radix) and added Shu Fuzi (Prepared Aconiti Lateralis Radix). Alternatively, if there is coldness of the four limbs and occasional convulsions, the pathogen is located in the Jueyin Meridian; warming is indicated using Yigong San (for slow eruption) added with Fangfeng (Saposhnikoviae Radix) and Qingpi (Citri Reticulatae Pericarpium Viride), or Baizhu San (for thirst) with Gan Ge (Puerariae Lobatae Radix) and Huoxiang (Agastaches Herba) removed, and added with Fuzi (Aconiti Lateralis Radix Praeparata) and Rougui (Cinnamomi Cortex).
In cases of pustular eruptions, there are patterns of Yang excess with Yin deficiency, and patterns of Yin excess with Yang deficiency. Those with Yang excess drink ice and snow without feeling cold; those with Yin excess drink boiling water without feeling heat. Any case presenting with fever and thirst, coldness of the hands and feet, spontaneous diarrhea, and a preference for hot drinks belongs to Yin excess with Yang deficiency; Xue uses Dayi Gong San (for slow eruption) and Bawei Wan to treat it. If there is fever and thirst accompanied by constipation, heat in both hands and feet, and a preference for cold drinks, this belongs to Yang excess with Yin deficiency; Xue uses Sishun Yin (clearing heat) and Dihuang Wan (nourishing Kidney) to treat it. If there is irritability, heat, and thirst, with a red face and white eyes, this is deficient heat in the Kidney Meridian; Dihuang Wan or similar formulas are also appropriate. Chen Wenzhong treated Yin excess with Yang deficiency using Dayi Gong San added with Muxiang (Aucklandiae Radix) and Danggui (Angelicae Sinensis Radix) to tonify Yang, which was correct. However, for Yang excess with Yin deficiency, he used Muxiang San added with Dingxiang (Caryophylli Flos) and Guanzi Gui (Cinnamomi Cortex), claiming to tonify Yin; is this not adding fire to fire? This is why Chen’s prescriptions were regarded as one-sided methods and ridiculed by earlier sages. If scholars fail to examine carefully and misuse them, the resulting premature deaths are too numerous to recount.
If voice remains present after sores and rashes have erupted, it indicates that the physical form is diseased but the Qi is not; if the body is warm, Jiedu Fangfeng Tang (general principle) should be used. If there is bowel obstruction, Danggui Wan (for constipation) is appropriate. If voice is absent before the eruption of sores and rashes, it indicates that the physical form is not diseased but the Qi is; Bufei San (for loss of voice) added with Sheng Huangqi (Raw Astragali Radix) is indicated. If sores and rashes have erupted but voice is absent, this indicates that both form and Qi are diseased; for children with innate constitutional weakness, Shiqi San (i.e., Shixuan San, see the stage of rising) should be taken in advance, with doubled Danggui (Angelicae Sinensis Radix) and Chuanxiong (Ligustici Chuanxiong Rhizoma), and a small amount of Muxiang (Aucklandiae Radix) decocted and taken orally. (Some say Shibu San or Dayi Gong San is suitable; others state that when both form and Qi are diseased, the Lung should be cleared, using Bafeng Tang, or Liangge San with Xiaoshi (Natrii Sulfas) and Dahuang (Rhei Radix et Rhizoma) removed as the primary treatment.)
