皇甫谧云∶凡治寒食药者，虽治得瘥，终不可以治者为恩也。非得治人后忘得效也。昔
文挚治齐王病，先使王怒而后治病已。王不思其愈而思其怒，文挚以是虽愈王病而终为王所
杀。今救寒食药者，要当逆常理，反正性，犯怒以治之，自非达者。已瘥之后，心念犯怒之
怨，必忘得治之思。犹齐王之杀文挚也。后与太子尚不能救，而况凡人哉。然死生大事也，
知可生而不救之，非仁者。唯仁者心不已，必冒怒而治之为亲戚之，故不但其一人而已。凡
此诸救，皆吾所亲更也。已试之验，不借问于他人也，大要违人理，反常性。
六反∶
重衣更寒，一反。（《外台方》云∶凡人寒，重衣即暖。服石人宜薄衣，若重衣更寒。《经
》云∶热极生寒。故云一反。）
饥则生臭，二反。（平人饱则食不消化，生食气。服石人忍饥失食节，即有生臭气，与
常人不同，故云二反。）
极则自劳，三反。（平人有所疲极即须消息恬养。服石人久坐卧疲极，唯须自劳，适散
石气即得宣散，故云三反。）
温则泄利，四反。（平人因冷乃利，得暖便愈。服石人温则泄利，冷则瘥，故云四反。）
饮食欲寒，五反。（平人食温暖则五内调和。服石人饮食欲寒乃得安稳，故云五反。）
痈疮水洗，六反。
七急∶
当洗勿失时，一急。
当食勿忍饥，二急。
酒清淳令温，三急。
衣温便脱，四急。
食必极冷，五急。
卧必底薄，六急。
食不厌多，七急。
八不可∶
冬寒欲火，一不可。
饮食欲得热，二不可。
常疾目疑，三不可。（凡服石人常须消息节度，觉少不安，将息依法治，不可生狐疑。）
畏避风温，四不可。（若觉头风热闷，愦愦心烦，则宜常当风梳头，以水洗手面即好，
不比寻常风湿。）
极不能行，五不可。（若久坐卧，有所疲极，必须行役自劳。）
饮食畏多，六不可。
居贪浓席，七不可。
所欲从意，八不可。
三无疑∶
务违常理，一无疑。
委心弃本，二无疑。
寝处必寒，三无疑。
若能顺六反，从七急，审八不可，定三无疑，虽不能终蠲此疾没齿无患者，庶可以释朝
夕之暴卒矣。
Huangfu Mi said: Regarding the treatment of patients suffering from "Han Shi Yao" (a type of mineral-based medication with hot and dry properties) toxicity, even if the cure is achieved, one should not ultimately claim credit for it. It is not that after curing a person, one forgets the efficacy. In the past, Wen Zhi treated the King of Qi's illness by first making the King angry, and then curing the disease. The King did not appreciate his recovery but harbored resentment for being angered; thus, although Wen Zhi cured the King of Qi's illness, he was ultimately killed by him. Now, when rescuing those who have suffered from Han Shi Yao toxicity, the key lies in going against common sense and reversing normal nature, using anger induction to treat them. Unless one is a wise person, after recovery, they will only think of the resentment caused by the induced anger and inevitably forget the gratitude for being cured. This is akin to the King of Qi killing Wen Zhi. Later, even the Crown Prince could not save him, let alone ordinary people. However, life and death are major events. Knowing that one can be saved but choosing not to rescue is not benevolent. Only those with endless benevolence will dare to risk angering the patient to provide treatment, not just for one individual, but for relatives and clansmen. All these rescue methods have been personally tested by me. Their efficacy has been verified, so there is no need to ask others. The general principle is to violate human norms and reverse normal habits.
Six Reversals (Six practices contrary to convention):
1. Wearing heavy clothes leads to feeling colder. (The *Waitai Miyao* states: Ordinary people feel cold and become warm by wearing heavy clothes. Those taking stone drugs should wear thin clothes; if they wear heavy clothes, they feel colder. The *Neijing* says: Extreme heat generates cold. Hence, this is called the first reversal.)
2. Hunger generates foul odor. (Ordinary people, when full, may suffer from indigestion and produce food-related gas. Those taking stone drugs endure hunger and lose regular eating rhythms, generating a putrid odor, which differs from ordinary people. Hence, this is called the second reversal.)
3. Self-labor at the point of extreme fatigue. (Ordinary people require rest and nourishment when extremely fatigued. Those taking stone drugs, when fatigued from long sitting or lying, must engage in self-labor to disperse the mineral qi, allowing it to spread. Hence, this is called the third reversal.)
4. Warmth causes diarrhea. (Ordinary people suffer diarrhea due to cold and recover with warmth. Those taking stone drugs experience diarrhea when warm and recover when cold. Hence, this is called the fourth reversal.)
5. Desire for cold food and drink. (Ordinary people achieve harmony of the five zang organs by consuming warm food. Those taking stone drugs feel secure only when consuming cold food and drink. Hence, this is called the fifth reversal.)
6. Washing carbuncles and sores with water.
Seven Urgencies (Seven urgent precautions):
1. Bathing must not be delayed when necessary.
2. Eating must not be endured as hunger when needed.
3. Wine should be clear, pure, and warmed.
4. Remove clothing once it becomes warm.
5. Food must be extremely cold.
6. Bedding must be low and thin.
7. Do not dislike eating large amounts.
Eight Don'ts (Eight things not to do):
1. Desiring fire for warmth in winter cold.
2. Desiring hot food and drink.
3. Constant visual ambiguity and doubt. (Those taking stone drugs must constantly monitor their condition. If feeling slightly unwell, follow proper recuperation methods; do not harbor doubts.)
4. Fearing and avoiding wind and warmth. (If one feels head wind-heat oppression and mental restlessness, one should comb hair facing the wind and wash face/hands with water. This is different from ordinary wind-dampness.)
5. Inability to walk due to extreme fatigue. (If fatigued from long sitting/lying, one must walk and labor.)
6. Fear of eating too much.
7. Coveting thick, soft mats for living quarters.
8. Letting desires follow one's whims.
Three Certainties (Three principles without doubt):
1. Must deliberately violate common sense.
2. Entrust oneself completely, abandoning conventional foundations.
3. Resting and dwelling must be in cold environments.
If one can follow the Six Reversals, adhere to the Seven Urgencies, examine the Eight Don'ts, and establish the Three Certainties, even if one cannot completely eradicate the disease until old age without illness, one might avoid sudden death in the morning or evening.
