Xu Renze believed that the manifestations of this disease present in several varieties. Some patients have pre-existing accumulations (chronic pathological products or masses within the body) and, due to improper diet during solar term transitions, may develop this illness. Others have phlegm-fluids (Tan Yin) accumulating internally for a long time without dispersing; when cold and heat pathogens attack each other, this disease also arises. Some reside in low-lying, damp areas and, during hot summer seasons, with internal chronic conditions and external exposure to foul miasmas (Hui Qi), also contract this disease. Still others, drinking cold substances during the intense heat of midsummer, cause cold and heat energies to intermingle; during the transition between autumn and summer, this disease may also occur. In summary, it ultimately stems from irregular diet and disharmony with cold and heat.
The treatment principle for this disease is based on emesis (inducing vomiting) and purgation (inducing diarrhea). However, individuals vary in robustness, and diseases differ in severity; one must adjust according to the specific situation at hand and cannot apply a uniform rule. There are cases where this disease heals through prayer and exorcism; this is merely a delusion of the mind, where fear or attachment causes illness, similar to mistaking an archer's bow shadow for a gu poison. If one firmly believes in this method without doubt, they may follow the path of exorcism and prayer. Nevertheless, medication must be utilized to save the patient. Recently, those treated with medicinal attacks have invariably recovered; whereas those treated only with exorcism often fail. This indicates that the disease lies internally, and futile efforts directed externally are useless.
At the onset, this disease resembles epidemic febrile diseases (Tian Xing) and presents with headache, soreness and pain in bones and muscles, cold extremities, dryness of the mouth, nose, throat, and tongue, thirst, piloerection (hair standing up), stiffness of the waist and spine with desire for retroflexion, and dark urine. The distinguishing feature is chills preceding fever, occurring at regular intervals, which must be carefully examined. The timing of attacks is precise. After seven days of illness, first administer the Bie Jia Wu Wei San (Turtle Shell Five-Ingredient Powder) to induce rapid vomiting.
[Bie Jia Wu Wei San / Turtle Shell Five-Ingredient Powder]
Bie Jia (Shell of Trionyx sinensis, 3 liang, raw); Chang Shan (Radix Dichroae, 2 liang); Gan Cao (Radix Glycyrrhizae, 2 liang, honey-fried); Song Luo (Usnea, 2 liang); Gui Xin (Cortex Cinnamomi, 1 liang).
Pulverize these herbs and sieve them into a powder. Take with decocted Wu Mei Tang (Mume Fruit Decoction). Initial dose: one Fang Cun Bi (a square-inch measure). Administer twice daily, gradually increasing the dose until vomiting occurs. Avoid eating Ren Xian (Amaranthus manihot), raw Cong (Allium fistulosum), raw vegetables, Hai Zao (Sargassum), and Song Cai (Brassica rapa var. pekinensis).
Re-evaluate the patient's condition. If physical strength is fully robust, administer twice daily, ensuring each dose induces vomiting. If self-perceived energy is not strong, ensure only one dose induces vomiting per administration, and do not take the evening dose. If the body is extremely weak like cotton, yet vomiting is necessary, administer once every three to five days. After five or six episodes of vomiting, simply regulate temperature appropriately, rest, and manage diet to gradually strengthen the constitution. If it is known that although the disease is mild and vomiting has occurred, the root cause remains uncleared, and purgation is required to drain the pathological trend, it is appropriate to compound and administer Dang Gui Liu Wei San (Angelica Sinensis Six-Ingredient Powder) to induce purgation.
[Dang Gui Liu Wei San / Angelica Sinensis Six-Ingredient Powder]
Dang Gui (Radix Angelicae Sinensis, 5 liang); Bai Zhu (Rhizoma Atractylodis Macrocephalae, 5 liang); Xi Xin (Herba Asari, 4 liang); Gui Xin (Cortex Cinnamomi, 3 liang); Da Huang (Radix et Rhizoma Rhei, 5 liang); Po Xiao (Natrii Sulfas, 4 liang).
Pulverize and sieve these herbs into a powder. Take in the morning on an empty stomach with wine. Initial dose: one Fang Cun Bi. Administer twice daily, gradually increasing the dose until purgation occurs. Assess the patient's strength to determine the extent of purgation, following the same principles as the emetic method above. Avoid Tao Li (Prunus persica), Que Rou (Pullet meat), raw Cong (Allium fistulosum), and raw vegetables.
Again, following the previous method, first use Bie Jia Wu Wei San to induce vomiting, then Dang Gui Liu Wei San to induce purgation. Although emesis and purgation have been performed, the source of the disease persists. If further emesis or purgation is considered, there is concern about weakening the patient further. Therefore, it is appropriate to compound and administer Gui Jian Yu Shi Wei Wan (Spiny Elm Ten-Ingredient Pill).
[Gui Jian Yu Shi Wei Wan / Spiny Elm Ten-Ingredient Pill]
Xi Xin (Herba Asari, 4 liang); Ju Pi (Pericarpium Citri Reticulatae, 4 liang); Gui Jian Yu (Ramulus Eucommiae Ulmoidis, select golden interior, 2 liang); Bai Zhu (Rhizoma Atractylodis Macrocephalae, 5 liang); Gui Xin (Cortex Cinnamomi, 4 liang); Di Gu Pi (Cortex Lycii, 4 liang); Shu Qi (Radix Dichroae, 2 liang); Gan Cao (Radix Glycyrrhizae, 3 liang, honey-fried); Dang Gui (Radix Angelicae Sinensis, 5 liang); Ding Xiang (Flos Caryophylli, 3 liang).
Pulverize and sieve these herbs, mix with honey, and form pills the size of wu zi (wu berry seeds). Take with decocted Wu Mei Yin (Mume Fruit Drink). Initial dose: 15 pills. Administer twice daily, gradually increasing to 30 pills. After taking the medicine for three to five days, if severe heat is felt, wait a long time after taking the medicine, then consume two or mouthfuls of porridge drink to suppress it. Avoid Hai Zao (Sargassum), Song Cai (Brassica rapa var. pekinensis), Tao Li (Prunus persica), Que Rou (Pullet meat), and raw Cong (Allium fistulosum).
Additionally, to treat this disease, Lu employed a formula from Shi Shen Shi, which is highly effective. This formula contains Ba Dou (Seminar Crotonis Tiglii), Zao Jiao (Fructus Gleditsiae Sinensis), and Li Lu (Radix Veratri NigrI). These three ingredients are formed into pills. Although the process may be arduous, a single dose can permanently eradicate the disease. (Wu Sheng's identical content appears in Volume I.)
