中湿之证∶一身尽疼，重者发黄、关节烦疼、发热、鼻塞，时或腹满胀大、便利，脉沉而缓。以上中
湿之证，先用双解散（五十四）微微汗之，次用五苓散（二十四）或淡渗散（二十五）、桂苓甘露饮（三十
四）。曾用甘露饮不愈，却用黄连解毒（二十一）则愈。问∶何也？曰∶若剂生土之甘，此属土，故以
火剂燥土，其病则愈。
风寒俱中之证∶头痛项强、肢体疼、手足温，为中风；反无汗、恶寒、脉浮紧，为伤寒也。
或头项疼、腰脊强、身体拘急、指末微厥、不自汗，为伤寒；反烦躁而脉缓者为伤风也。风则伤卫，寒
则伤荣，荣卫俱伤，则表里热甚者，通宜以大青龙汤（六），或双解散（五十四）最妙。
始得脉便沉而里病表和者，内伤也；脉浮而表病里和者，外伤也。病在身体四肢，为表病；病在胸
腹之内，为里病。内伤通神散（五十一），外伤双解散（五十四），内外一切所伤通圣散（五十三），
然不若双解散，以平和为之，三法至神。
风寒暑湿、饥饱劳逸、忧愁思虑、恚恐悲怒；四时中外诸邪所伤，但觉身热
头疼、拘倦强痛，无问自汗无汗、憎寒发热、渴与不渴，微、甚；伤寒疫疠、汗
病两感、风气杂病，一切旧病发作，三日里外并宜双解散（五十四）。设若感之势甚，本难解者，常
服双解散，三两日间，亦渐可减，并无所损。或里热极甚、腹满实痛、烦渴谵妄，须可下者，三一承气汤
（十三）为妙。或下后未愈，或下证未全，或大汗前后逆气，或汗后余热不解，或遗热复劳，或染他人
病气，汗毒传染，或中瘴气、羊气、牛气，一切秽毒，并漆毒、酒毒、食毒、一切药毒，及坠
堕打扑伤损疼痛，或久患风眩头疼、中风偏枯、破伤风、洗头风、风痫病，或妇人产后诸疾，小儿惊
风积热、疮疡疹痘，无问日数，但以双解散（五十四）服之，周身中外气血宣通，病皆除愈。然双解
乃通仙之药，但除孕妇及产后、月经过多、并泄泻者勿与服之，惟年老人最宜，自有造化于中矣。
中湿的证候：全身疼痛，严重的出现发黄、关节剧烈疼痛、发热、鼻塞，有时腹部胀满变大、大便通畅或泄泻，脉象沉而缓。以上这些中湿的证候，先用双解散（第五十四方）微微发汗，接着用五苓散（第二十四方）或者淡渗散（第二十五方）、桂苓甘露饮（第三十四方）。如果曾用过甘露饮没有痊愈，改用黄连解毒汤（第二十一方）则能痊愈。问：为什么呢？答：如果药性具有生土之甘味，这属于土性，所以用火性药物来燥湿健脾，病就能痊愈。
风寒同时侵袭的证候：头痛项强、肢体疼痛、手足温暖，这是中风；反而无汗、恶寒、脉浮紧，这是伤寒。或者头项疼痛、腰脊僵硬、身体拘挛紧急、手指末端微冷、不出汗，这是伤寒；反而烦躁且脉缓的是伤风。风邪伤害卫气，寒邪伤害营血，营卫都受伤，导致表里热势严重的，通常适宜用大青龙汤（第六方），或者双解散（第五十四方）最为巧妙。
刚发病时脉象就沉且里有病而表里调和的，是内伤；脉象浮而表有病而里调和的，是外伤。病在身体四肢，称为表病；病在胸腹之内，称为里病。内伤通用神散（第五十一方），外伤通用双解散（第五十四方），内外一切所伤通用通圣散（第五十三方），然而不如双解散，因为它性质平和，这三种方法极为神妙。
风寒暑湿、饥饱劳逸、忧愁思虑、愤怒恐惧悲伤；四季内外各种邪气所伤，只要觉得身体发热、头疼、拘挛疲倦强痛，不问自汗还是无汗、憎寒发热、口渴还是不渴，病情轻微或严重；伤寒疫病、两感证、风气杂病，一切旧病发作，三天内表里都适宜服用双解散（第五十四方）。假如感受邪气之势很盛，本来难以解除的，常服双解散，三两日间，也能逐渐减轻，并没有损害。或者里热极盛、腹部胀满实痛、烦躁口渴胡言乱语，需要攻下的，三一承气汤（第十三方）最为巧妙。或者攻下后未愈，或者下证不完全，或者大汗前后逆气，或者汗后余热不解，或者余热复发因劳累引起，或者感染他人的病气，汗毒传染，或者中瘴气、羊气、牛气，一切秽毒，以及漆毒、酒毒、食毒、一切药毒，以及坠跌打扑损伤疼痛，或者久患风眩头疼、中风偏枯、破伤风、洗头风、风痫病，或者妇人产后诸疾，小儿惊风积热、疮疡疹痘，不论多少天，只要服用双解散（第五十四方），周身内外气血宣通，病都能除去痊愈。然而双解乃是通达仙境的药物，只是要除去孕妇及产后、月经过多、以及泄泻的人不要服用它，只有老年人最适合，其中自有造化之功。
Syndrome of dampness: Pain throughout the entire body; in severe cases, jaundice (yellowing of skin and eyes), severe joint pain, fever, nasal congestion; sometimes abdominal distension and enlargement, with normal or loose stools. The pulse is deep and slow. For the above-mentioned syndromes of dampness, first use Shuangjie San (Double-Resolving Powder) to induce mild sweating, followed by Wuling San (Five-Ingredient Poria Pill) or Danshen San (Light-Purging Powder), or Guiling Ganlu Yin (Cassia Twig and Atractodes Sweet Dew Decoction). If Guiling Ganlu Yin fails to cure, switching to Huanglian Jiedu Tang (Coptis Decoction for Detoxification) will result in recovery. Question: Why? Answer: If the medicinal properties possess the sweet flavor that generates Earth, it belongs to the Earth element. Therefore, using Fire-natured drugs to dry Dampness and strengthen Spleen Earth leads to recovery.
Syndrome of simultaneous invasion by wind and cold: Headache, stiffness of the neck, limb pain, and warm hands and feet indicate Wind-stroke (Zhongfeng); conversely, absence of sweat, aversion to cold, and a floating-tight pulse indicate Cold damage (Shanghan). Alternatively, headache and neck pain, stiffness of the waist and spine, bodily rigidity and urgency, slight coldness at the fingertips, and absence of spontaneous sweating indicate Cold damage; conversely, irritability and a slow pulse indicate Wind injury. Wind injures Wei Qi (Defensive Qi), while Cold injures Ying Blood (Nutritive Blood). When both Ying and Wei are injured, resulting in severe heat in both exterior and interior, Dachinglong Tang (Major Blue Dragon Decoction) is generally appropriate, or Shuangjie San (Double-Resolving Powder) is most excellent.
If the pulse is deep from the onset with internal pathology but external harmony, it is an Internal Injury (Neishang); if the pulse is floating with external pathology but internal harmony, it is an External Injury (Waishang). Pathology located in the body and four limbs is termed Exterior Disease (Biao Bing); pathology within the chest and abdomen is termed Interior Disease (Li Bing). For internal injuries, Tongshensan (Godly Spirit Powder) is used; for external injuries, Shuangjie San (Double-Resolving Powder) is used; for all types of internal and external injuries, Tongsheng San (Universal Protection Powder) is used. However, Shuangjie San (Double-Resolving Powder) is preferable due to its balanced nature; these three methods are highly effective.
Injuries caused by wind, cold, summerheat, dampness, hunger, fullness, overwork, rest, worry, thought, anger, fear, and sorrow; various pathogens from the four seasons affecting the interior and exterior. Whenever there is fever, headache, rigidity, fatigue, and painful stiffness, regardless of spontaneous sweating or lack thereof, aversion to cold with fever, thirst or lack of thirst, and whether the condition is mild or severe; for cold damage, epidemics, Lianggan syndrome (simultaneous involvement of two meridians), miscellaneous wind diseases, and exacerbations of old diseases, Shuangjie San (Double-Resolving Powder) is suitable for both interior and exterior within three days. If the pathogenic influence is strong and difficult to resolve initially, regular consumption of Shuangjie San over two to three days can gradually alleviate symptoms without causing harm. In cases of extreme interior heat, abdominal fullness and solid pain, irritability, thirst, and delirium requiring purgation, Sanyi Chengqi Tang (Three-One Descending Qi Decoction) is optimal. If not cured after purgation, if purgative indications are incomplete, if rebellious Qi occurs before or after profuse sweating, if residual heat persists after sweating, if residual heat recurs due to exertion, if infected by others' pathogenic qi, transmitted via sweat toxins, or affected by miasma, sheep qi, cattle qi, all foul toxins, as well as lacquer toxicity, alcohol toxicity, food toxicity, drug toxicity, trauma from falls or blows, chronic dizziness and headaches, stroke with hemiplegia, tetanus, "washing head wind," wind epilepsy, postpartum disorders in women, infantile convulsions with accumulated heat, sores, ulcers, rashes, and smallpox, regardless of the number of days, administering Shuangjie San (Double-Resolving Powder) promotes the free flow of Qi and Blood throughout the body and interior-exterior, leading to complete recovery. However, Shuangjie San is a potent remedy; it should be avoided in pregnant women, postpartum women, those with excessive menstrual bleeding, and those with diarrhea. It is most suitable for the elderly, who will benefit from its transformative power.
