Wang Yongzhi, the Imperial Carriage Driver, suddenly collapsed into unconsciousness, with deviation of the mouth and eyes (facial paralysis), phlegm-qi surging upward causing sounds in the throat, and all six pulses deep and hidden. This was due to deficiency of True Qi allowing Wind pathogen to invade. He was treated with San Sheng Yin (Three Lives Decoction) one liang, added with Ren Shen (Ginseng Root) one liang, decocted and taken orally, after which he immediately regained consciousness. If symptoms such as urinary incontinence, hand relaxation (open palm unable to grasp), open mouth (inability to close lips), and snoring sleep occur, it is considered incurable; however, there are cases where using the aforementioned medicine resulted in survival. The aforementioned drink is a medicine that unblocks meridians and treats Cold Phlegm, possessing the power of breaking through defenses and defeating enemies. Each dose must be accompanied by approximately one liang of Ren Shen to drive out the pathogen and supplement True Qi; otherwise, it is not only ineffective but sufficient to cause defeat [worsening of condition]! Observing the ancients' use of Fu Zi (Aconite Lateral Root) and Shen Fu Tang (Ginseng and Aconite Decoction), their meaning can be understood.

Jiang Dayong, Prefectural Judge, had a robust physique, fullness in the middle jiao (epigastric region), profuse expectoration, dizziness upon exertion, and had previously taken medicines for clearing Phlegm and regulating Qi. I said: Fullness in the middle jiao indicates Spleen Qi deficiency; profuse Phlegm indicates Spleen Qi's inability to transform and transport; dizziness indicates Spleen Qi's inability to ascend; numbness in fingers indicates Spleen Qi's inability to circulate throughout the body. Thus, Bu Zhong Yi Qi Tang (Decoction to Supplement the Middle and Augment the Qi) was used with Fu Ling (Poria) and Ban Xia (Pinellia Tuber) to tonify Spleen Earth, and Ba Wei Di Huang Wan (Eight-Ingredient Pill with Rehmannia) was used to tonify the Mother of Earth (Kidney), resulting in recovery. Later, influenced by *Qian Kun Sheng Yi Fang* stating that anyone with numb and soft fingers will suffer from stroke within three years, and suggesting the preventive use of Sou Feng Wan (Wind-Searching Pill) and Tian Ma Er Wan (Two Pills with Gastrodia), he took them morning and night. This led to fecal incontinence, loss of appetite, and death. I believe the principle of prevention should involve nourishing Qi and Blood, moderating diet, restraining the Seven Emotions, and avoiding sexual activity. Taking the aforementioned pills for prevention merely invites Wind and induces stroke.

A man suffered sudden collapse, deviation of the mouth and eyes, aphasia, and limb spasms upon exposure to Wind-Cold, with a floating and tight pulse. This indicated deficiency of the Hand and Foot Yangming Meridians, invaded by Wind-Cold. Qin Jiao Sheng Ma Tang (Gentian and Cimicifuga Decoction) was used, leading to slight improvement, followed by Bu Zhong Yi Qi Tang added with Shan Zhi (Gardenia Fruit) for complete recovery. If tongue stiffness with inability to speak and leg flaccidity with inability to walk occur, it belongs to Kidney Qi weakness, named Fei Syndrome (Flaccidity Syndrome), and should be treated with Di Huang Yin Zi (Rehmannia Infusion). However, these conditions all arise from improper regimen, insufficient Kidney Water, and violent Heart Fire, with Phlegm stagnating in the chest. Mild cases recover spontaneously; severe cases may result in death.

A man, obese and fond of drinking alcohol, presented with a stiff tongue base, unclear speech, deviation of the mouth and eyes, surging Phlegm-qi, and limb dysfunction. I diagnosed this as Spleen Deficiency with Damp-Heat, treating him with Liu Jun Zi Tang (Six Gentlemen Decoction) added with Wei Ge Gen (Baked Kudzu Root), Shan Zhi, and Shen Qu (Medicated Leaven), resulting in recovery.

My teacher, Gao Ruzhai, Vice Commissioner, returned from Datong and told me, "I have contracted Wind disease." He described his legs as flaccid and weak when at rest, and painful like needle pricks upon exertion, with a surging, rapid, and forceful pulse. I informed him: This is Liver and Kidney Yin Deficiency with Hyperactive Fire, causing flaccidity and weakness, which is the form of the true disease; pain like cone piercing is the image of Evil Fire. He recovered using medicines to enrich Water and tonify the Kidney. Mr. Gao said, "Previously residing in the official residence, everyone believed it was Wind disease. I regretted the lack of medical treatment then; if I had taken Wind-dispelling agents, would it have been so? It was my fortune." I privately note that previous cases were often mistaken for Wind diseases, and thorough use of dispersing agents frequently accelerated critical decline.

Liu Mengchun, County Magistrate, had chronic Phlegm, numbness in both arms, and tearing eyes. After taking Wind-dispelling and Phlegm-resolving medicines, the Phlegm increased, arms became painful and immobile, and fingers contracted. I said: Numbness belongs to Excess Qi; because previous medicines injured the Liver, Fire Excess caused tendon contraction. Moreover, Wind arises from Fire; one should tonify Spleen and Lung, nourish Kidney Water, so that Wind subsides, Heat retreats, and Phlegm clears. He was treated with Liu Wei Di Huang Wan (Six-Ingredient Pill with Rehmannia) and Bu Zhong Yi Qi Tang, recovering in less than three months.

A scholar, accustomed to hard work, feared Wind and Cold, had nasal congestion with clear discharge, and sneezing in cold weather. I said: This is Spleen and Lung Qi deficiency failing to secure the Cou Li (interstices). He did not believe this, took Wind-dispelling medicines, and developed limb numbness and fatigue with spontaneous salivation, resembling stroke. I said: This is due to Wind agents depleting Yuan Qi, allowing Yin Fire to attack the Earth position. He was treated with Bu Zhong Yi Qi Tang added with Mai Men Dong (Ophiopogon Tuber) and Wu Wei Zi (Schisandra Berry) and recovered.

My maternal grandfather, over sixty years old, fond of drinking, suffered arm pain. Strictly taking Wind-dispelling and flaccidity-treating medicines worsened his condition with numbness, fever, body softness, surging Phlegm, knee and leg spasms, trismus with dysarthria, heavy dizziness, drooling, itching sensation like insects crawling on the skin with white scales upon scratching. Only then did he believe me. He asked why. I said: Arm numbness and body softness indicate Spleen failure; spontaneous salivation indicates Spleen's inability to control; mouth deviation and dysarthria indicate Spleen Qi injury; heavy dizziness indicates Spleen Qi's inability to ascend; itching with white scales indicates Spleen Qi's inability to nourish. He was treated with Bu Zhong Yi Qi Tang added with Shen Qu, Ban Xia, and Fu Ling for over thirty doses, all symptoms receded, and further treated with Shen Zhu Jian Gao (Ginseng and Atractylodes Paste) for recovery.

Liu Yungong, Scholar, robust in build, careless with alcohol and sex, fainted from dizziness due to labor and anger, with surging Phlegm-saliva, limb numbness, dry mouth with desire to drink, and surging, rapid, yet empty pulses. I diagnosed Kidney Meridian deficiency, unable to receive Qi back to its source causing dizziness; unable to control water returning to source causing Phlegm; Yang Qi deficiency heat causing numbness; deficient Fire flaming upward causing thirst. He was treated with Bu Zhong Yi Qi Tang combined with Liu Wei Di Huang Wan ingredients and recovered. Subsequently, whenever he labored or engaged in intercourse, the illness recurred, resolving promptly with the previous medicines.

Gu Feizhai, Constitutional Secretary, had irregular diet and lifestyle, presenting with left-side hemiplegia, sweating, coma, and surging Phlegm-saliva. Wang Zhuxi used large tonifying agents containing Ren Shen; sweating stopped, mental clarity gradually returned, and walking ability improved. Later, violating taboos, his left leg swelled massively from knee to foot, heavy and stone-like, unbearable pain, with excessive Phlegm. Liver, Spleen, and Kidney pulses were surging, rapid, and large, but soft and choppy upon heavy pressure. In the morning, I used Bu Zhong Yi Qi Tang added with Huang Bo (Phellodendron Bark), Zhi Mu (Anemarrhena Rhizome), Mai Men Dong, and Wu Wei Zi, decocted and taken with Di Huang Wan; in the evening, Di Huang Wan ingredients added with Huang Bo and Zhi Mu. After several doses, all symptoms receded. However, due to relaxing restrictions, complete cure was not achieved.

Chen Shi Yong, Student, accustomed to hard work, suffered mouth deviation and profuse Phlegm due to labor and anger, with slippery, rapid, and empty pulses. This was Labor injuring Middle Qi and Anger stirring Liver Fire. He was treated with Bu Zhong Yi Qi Tang added with Shan Zhi, Fu Ling, Ban Xia, and Jie Geng (Platycodon Root), recovering after several doses.

Yang Yongxing, Gentleman of the Imperial Guard, plump in body, suffered soft and painful bones and tendons, profuse Phlegm, thirst, and preference for cold drinks. Others used Yu Feng Tang (Wind-Healing Decoction) and Tian Ma Wan (Gastrodia Pill), worsening Phlegm-Heat. After taking Niu Huang Qing Xin Wan (Calculus Bovis Clearing Heart Pill), limb numbness increased. I diagnosed dual deficiency of Spleen and Kidney, treating him with Bu Zhong Yi Qi Tang and Jia Jian Ba Wei Wan (Modified Eight-Ingredient Pill with Rehmannia), recovering after more than three months. He subsequently fathered seven sons and lived past seventy. *Wai Ke Jing Yao* states: Anyone who takes Jia Jian Ba Wei Wan long-term will become fat, healthy, and fertile.

My late mother, aged seventy-five, suffered whole-body pain, especially in bones and tendons, inability to extend or flex, dry mouth, red eyes, dizziness, Phlegm obstruction, chest discomfort, short dark urine, worse at night, and whole-body itching like insects crawling. She was treated with Liu Wei Di Huang Wan ingredients added with Shan Zhi and Chai Hu (Bupleurum Root), and all symptoms resolved.

A man, after healing from syphilitic sores, suffered whole-body pain. After taking Yu Feng Dan (Wind-Healing Pill), he developed hemiplegia, surging Phlegm-saliva, and severe night pain. I treated this as Wind invading and contaminating Qi, curing him with Di Huang Wan (Rehmannia Pill).

An elderly man, with impaired movement of both arms and dysarthria. After taking Wind-dispelling medicines, he developed tendon contraction and bone pain. This was Wind medicines damaging Liver Blood, exacerbating the disease. I used Ba Zhen Tang (Eight-Treasure Decoction) to tonify Qi and Blood, Di Huang Wan to tonify Kidney Water, assisted by Yu Feng Dan, resulting in recovery.

A woman, vomiting Phlegm due to anger, with chest fullness and pain, did not respond to Si Wu Tang (Four Substance Decoction), Er Chen Tang (Two Aged Decoction), Huang Qin (Scutellaria Root), Lian Zi (Lotus Plumule), Zhi Qiao (Aurantium Fructus). Adding Wind-dispelling agents led to hemiplegia, gradual tendon contraction, limb flaccidity, worsening in the afternoon, internal heat, dry mouth, and fatigue. I diagnosed Depression and Anger injuring Spleen and Liver, with subsequent Qi and Blood damage. She was regulated with Xiao Yao San (Free and Easy Wanderer Powder), Bu Zhong Yi Qi Tang, and Liu Wei Di Huang Wan. Fortunately, she was diligent in her treatment, and after over a year, she fully recovered with healthy physique.

A woman with weak Spleen and Stomach and poor appetite suddenly presented with surging Phlegm, panting, head shaking, eye blinking, hand waving, and leg kicking, making pulse diagnosis difficult. Her complexion showed yellow with green tinges, indicating Liver Wood overacting on Spleen Earth. She was revived with Liu Jun Zi Tang added with Chai Hu and Sheng Ma (Cimicifuga Rhizome), and later regulated with Bu Zhong Yi Qi Tang added with Ban Xia for recovery.

A woman with emotional depression suffered tendon contraction and bone pain, with a sensation of a lump in the throat. After taking Wu Yao Shun Qi San (Tsaoko Regulating Qi Powder), she developed mouth deviation, inability to raise arms, increased Phlegm-saliva, internal heat, afternoon fever, poor appetite, and fatigue. I diagnosed Depressive Fire injuring Spleen, Blood Dryness generating Wind. She was treated with Jia Gui Pi Tang (Modified Restore the Spleen Decoction) for over twenty doses, gradually strengthening her physique and increasing appetite. Then, Jia Xiao Yao San (Modified Free and Easy Wanderer Powder) for ten doses reduced Phlegm-Heat and throat lump sensation. Further, Sheng Yang Yi Wei Tang (Raise Yang and Benefit Stomach Decoction) for several doses improved all symptoms, except arm extension, which was due to Liver Blood deficiency, cured with Di Huang Wan.

A postpartum woman suffered tendon contraction, arm weakness, and muscle twitching, indicating dual deficiency of Qi and Blood with Heat. She recovered with Shi Quan Da Bu Tang (Complete Great Tonifying Decoction). Later, relapse occurred due to anger, cured with Jia Xiao Yao San.

A postpartum woman suffered hand numbness. After taking Yu Feng Dan and Tian Ma Wan, whole-body numbness, mental fatigue, afternoon fever, thirst, spontaneous sweating, and night sweats appeared, indicating dual deficiency of Qi and Blood. She was treated with Shi Quan Da Bu Tang added with Pao Jiang (Prepared Ginger) for several doses, all symptoms receded. Removing Pao Jiang and continuing for several doses led to recovery. Internal heat was later cured with Jia Xiao Yao San.

A man fond of drinking presented with a stiff tongue base and unclear speech. I said: This is Spleen Deficiency with Damp-Heat, to be treated with Bu Zhong Yi Qi Tang added with Shen Qu, Mai Ya (Barley Sprout), Gan Ge (Kudzu Root), and Ze Xie (Alisma Rhizome).

A woman prone to anger presented with a stiff tongue base and arm numbness. I said: The tongue base belongs to Earth, constrained by Wood. It should be treated with Liu Jun Zi Tang added with Chai Hu and Shao Yao (Peony Root).

A man presented with tension under the tongue, insensitivity in the thumb and index finger, occasional constipation, or red skin halos. I said: The Large Intestine meridian scatters under the tongue. This is Large Intestine Blood Deficiency with Wind-Heat, to be treated with Xiao Yao San added with Huai Jiao (Stylocarpus Fruit) and Qin Jiao (Gentiana Macrophylla Root).

A man presented with foot flaccidity and afternoon fever. I said: This is deficiency of the Three Yin Meridians of the Foot, to be supplemented with Liu Wei Di Huang Wan and Zi Shen Er Wan (Two Pills for Nourishing the Kidney).

A woman presented with weak legs and feet, fatigue upon exertion. I said: The four limbs belong to Earth; this belongs to Spleen Deficiency, to be primarily treated with Bu Zhong Yi Qi Tang and Hai Shao Dan (Preserve Youth Pill).
None followed my advice, insisting on taking Sou Feng Wan, Tian Ma Er Wan, and Yu Feng Dan, resulting in death.
