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。
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.
