After consuming *Fuzi* (Aconite Lateralis Radix Praeparata), if the body and eyes turn red, it is due to the toxicity of Aconite. Immediately use a large bowl of juice from crushed raw radish (*Raphani Semen*, though context implies root juice, text says "luobo", usually Radix Raphani or similar, here interpreted as Radish Juice), add five qian of *Huanglian* (Coptidis Rhizoma), five qian of *Gancao* (Glycyrrhizae Radix et Rhizoma), and two qian of *Xijiao* (Rhino Ceratops Horn). Decoct until eight-tenths remains, then drink; the toxicity will be resolved. If treatment is delayed, blood will inevitably flow from the seven orifices, and death is certain. If fresh radish juice is unavailable, radish seeds may be used. Alternatively, soak raw soybeans (*Sojae Semen Album*) thoroughly, crush them, extract one cup of juice, and drink it; this also works. Or drink clarified muddy water; this also works.

After consuming *Dahuang* (Rhei Radix et Rhizoma), if diarrhea persists, use two *Wumei* (Mume Fructus), a pinch of stir-fried *Jingmi* (Oryza Sativa Var. Glutinosa), two qian of *Ganjiang* (Zingiberis Rhizoma), one qian of earth-stir-fried *Baizhu* (Atractylodis Macrocephalae Rhizoma), five fen of *Renshen* (Ginseng Radix), half a qian of peeled *Fuzi* (Aconiti Lateralis Radix Praeparata), seven fen of *Gancao* (Glycyrrhizae Radix et Rhizoma), two fen of *Shengma* (Cimicifugae Rhizoma), and seven roots of *Dengxin* (Junci Medulla). Decoct until cooked, add one spoonful of wall soil (*Bitu*), mix well, and take orally; the diarrhea will stop.

After consuming *Mahuang* (Ephedrae Herba), if sweating continues uncontrollably, spread the patient's hair into a basin of water, leaving the feet exposed outside. Then, take half a sheng of stir-fried glutinous rice (*Oryza Sativa Var. Glutinosa*), one liang of *Longgu* (Fossilia Ossis Mastodi et Humeri), one liang of *Muli* (Concha Ostreae), and one liang of *Bifengfeng* (Saposhnikoviae Radix - note: text says "Ben Fangfeng", likely referring to Saposhnikoviae Radix or similar aromatic wind-dispelling herb, standard is Fangfeng). Grind into fine powder and dust over the entire body.

*Qin* (Scutellariae Radix), *Lian* (Coptidis Rhizoma), *Zhi Mu* (Anemarrhenae Rhizoma), and *Bai Pi* (Phellodendri Cortex) are used for diseases of the head, face, and skin of the hands. Slightly stir-fry with wine to borrow the wine's power to ascend the medicinal action. For diseases below the throat but above the chest, slightly soak in wine. For diseases below the navel, use raw. Cooked herbs ascend; raw herbs descend. For all upper-jiao medicines, must soak in wine and dry in the sun. *Huang Bo* (Phellodendri Cortex) and *Zhi Mu* (Anemarrhenae Rhizoma) are originally medicines for the lower part. For people with chronic weakness, they must be soaked in wine and dried in the sun to prevent cold nature from damaging the stomach. *Da Huang* (Rhei Radix et Rhizoma) is stir-fried with wine; *Sheng Di Huang* (Rehmanniae Radix) and *Shu Di Huang* (Rehmanniae Radix Preparata) are washed with wine; all follow this principle.

When using *Fuzi* (Aconiti Lateralis Radix Praeparata), remove the skin and umbilicus. First, put half a bowl of salt water and half a bowl of ginger juice into a clay pot, boil six or seven times. Then add five qian of *Huanglian* (Coptidis Rhizoma), five qian of *Gancao* (Glycyrrhizae Radix et Rhizoma), and *Tongbian* (Child's Urine). Boil six or seven times, let stand for a long time, then remove. Store in a porcelain vessel, place on the ground overnight to eliminate earth qi, dry in the sun, and set aside for use. When using *Mahuang* (Ephedrae Herba), remove the nodes. Soak briefly in boiling vinegar and dry in the sun to prevent excessive sweating. In winter, or for patients with exterior excess syndrome, use raw *Mahuang*. When using *Wuyu* (Evodiae Fructus)... [Text cuts off]

Medicines have different densities of aroma and taste, varying weights, mixed cold and hot properties, and intermingled yin and yang attributes. Some have the same aroma but different tastes, or the same taste but different aromas. Clear yang emanates from the couli (interstices) and fills the four limbs; this is the clearest of the clear. Turbid yin travels to the five zang organs and returns to the six fu organs; this is the turbiddest of the turbid. The clearest of the clear nourishes the spirit; the turbiddest of the turbid strengthens the bone marrow. Qi belongs to Yang; dense qi is Pure Yang, thin qi is Yin within Yang. Thin qi causes dispersal and emission; dense qi causes fever. Taste belongs to Yin; dense taste is Pure Yin, thin taste is Yang within Yin. Thin taste promotes circulation; dense taste causes purgation. Pungent, sweet, and bland flavors disperse and are Yang; sour and bitter flavors induce vomiting and purgation and are Yin. Bland flavor permeates and drains and is Yang; sour and bitter flavors induce vomiting and purgation and are Yin. Pungent, sweet, and bland hot medicines are Yang within Yin; sour, bitter, and salty cold medicines are Yin within Yang. For example, *Fuling* (Poria) is bland and belongs to Heaven's Yang. Yang should ascend, so why does it promote urination and drain downward? The *Neijing* states that thin qi is Yin within Yang, thus it promotes urination and drains downward. However, draining downward still adheres to the nature of Yin, so it enters the Taiyin channel. *Mahuang* (Ephedrae Herba) is sweet and belongs to Earth's Yin. Yin should descend, so why does it induce sweating and ascend? The *Neijing* states that thin taste is Yang within Yin, thus it induces sweating and ascends. However, ascending still adheres to the nature of Yang, so it enters the Taiyang channel. *Fuzi* (Aconiti Lateralis Radix Praeparata) has both dense aroma and taste, its nature is hot, and it is Yang within Yang, hence the classics say it causes fever. *Da Huang* (Rhei Radix et Rhizoma) has both dense aroma and taste, its nature is cold, and it is Yin within Yin, hence the classics say it causes purgation. *Dan Zhu* (Bambusa Textilis Caulis) is Yang within Yin, so it benefits urination. *Ku Cha* (Camellia Sinensis Folium) is Yin within Yang, so it clears the head and eyes.

Medicines possess the qi of Cold, Heat, Warm, Cool, and Neutral; the flavors of Pungent, Sweet, Bland, Bitter, Sour, and Salty; the properties of Ascending, Descending, Floating, and Sinking; and the functions of Diffusing, Unblocking, Tonifying, and Draining. The *Neijing* says, tonification and drainage depend on the taste, and qi changes with the seasons. Therefore, ascending and dispersing is used to scatter pathogenic factors trapped in the exterior. Sweet flavors are used to moderate, alleviating extreme heat or cold. Bland flavors are used to percolate, draining internal dampness and benefiting urination. Bitter flavors are used to purge, clearing upward-flaring fire. Sour flavors are used to astringe, consolidating scattered essence. Salty flavors are used to soften, resolving dryness and congealed fire. In spring, when qi is warm, cool medicines are appropriate. In summer, when qi is hot, cold medicines are appropriate. In autumn, when qi is cool, warm medicines are appropriate. In winter, when qi is cold, hot medicines are appropriate. This is the standard practice for the four seasons. However, if the disease contradicts the season, these rules do not strictly apply. For instance, although dispersing is contraindicated in summer, if there is an extremely severe exterior excess syndrome, what harm is there in using one liang of *Mahuang* (Ephedrae Herba)? Other cases can be deduced by analogy. If the disease is in the upper part, ascending medicines should be used. If the disease is in the lower part, descending medicines should be used. If the disease is in the exterior, floating medicines should be used. If the disease is in the interior, sinking medicines should be used. Hence, the classics say, "Follow the ascending, descending, floating, and sinking," meaning to conform to the natural properties of the medicinal flavors' movement. Cold
