If both the Cun (inch) and Chi (cubit) pulses are floating, it indicates that the Taiyang (Greater Yang) channel is affected. Symptoms typically manifest within one to two days because this channel connects upward to the Fengfu (GV16) acupoint, resulting in headache, stiffness of the neck and occiput, and rigidity of the lower back and spine. (This refers to the Taiyang Bladder Channel, which belongs to Water; *Zhu Bing Yuan Hou Lun* claims it is the Small Intestine Channel, which is incorrect.)

In Taiyang disease, if there is fever, sweating, aversion to wind, and a slow pulse, it is named Wind Strike (Zhongfeng). In Taiyang disease, whether fever has already appeared or not, there must be aversion to cold, body pain, and a tight pulse at all three positions (Yin and Yang), which is named Cold Damage (Shanghan).

On the first day of Cold Damage, when the pathogen is in the Taiyang channel, if the pulse remains calm (unchanged), it indicates no transmission; however, if the patient desires to vomit, feels irritable, and the pulse is rapid and urgent, it indicates transmission.

On the second or third day of Cold Damage, if symptoms of Yangming (Yang Brightness) or Shaoyang (Lesser Yang) diseases do not appear, it indicates no transmission. Fever accompanied by aversion to cold indicates the pathogen originating from the Yang channels; absence of fever but presence of aversion to cold indicates the pathogen originating from the Yin channels. Those originating from Yang channels recover in seven days; those originating from Yin channels recover in six days, due to the numerical attributes of Yang being seven and Yin being six. (For pathogens originating from Yang channels, diaphoretic agents are used according to the syndrome to attack the exterior; for those originating from Yin channels, Si Ni Tang (Four Counterflow Decoction) type formulas are used to warm the interior.)

In Taiyang disease, if headache persists for more than seven days and resolves spontaneously, it is because the cycle of the channel has completed. If there is a concern about transmission to the next channel (Yangming), needling the Foot-Yangming Stomach Channel can prevent transmission. (This supplements the Earth of Yangming, specifically the Zusanli (ST36) acupoint.)

If caused by Wind pathogen, and after using exterior-releasing methods the condition is not fully resolved, recovery takes twelve days. (*Fangyan* states: In southern Chu, recovery from illness is called "chai" or "liao".)

In Taiyang disease, if Gui Zhi Tang (Cinnamon Twig Decoction) is administered initially but results in increased irritability without relief, one should first needle Fengchi (GB20) and Fengfu (GV16), then administer Gui Zhi Tang again for cure.

In Taiyang disease, with spontaneous sweating and difficulty bending/extending the limbs, if accompanied by difficult urination, Yang Dan Tang (Morning Sun Decoction) with one processed Fuzi (Aconiti Lateralis Radix Preparata) added is appropriate. The Fuzi should be processed, skin and tip removed, cut into eight pieces, and decocted together. (Yang Dan Tang is an alternative name for Gui Zhi Tang.) If urination is frequent, this formula must be avoided; instead, Shao Yao Gan Cao Tang (Peony and Licorice Decoction) is suitable. If Guizhi Fuzi Tang (Cinnamon Twig and Aconite Decoction) is mistakenly used to attack the exterior, leading to dry throat, irritability, cold extremities, and vomiting, Gan Cao Gan Jiang Tang (Licorice and Dried Ginger Decoction) should be given to restore Yang Qi. Once cold extremities resolve and feet become warm, Shao Yao Gan Cao Tang should be given again to extend the legs. If stomach Qi is disharmonious and delirium occurs, a small amount of Tiao Wei Cheng Qi Tang (Regulate the Stomach and Direct Downward the Qi Decoction) should be given; slight loose stools will stop the delirium.

Shao Yao Gan Cao Tang (Peony and Licorice Decoction) primarily treats floating pulse with spontaneous sweating, frequent urination, and a large, floating pulse at the Cun position. Floating indicates Wind, Large indicates Deficiency. Wind generates slight heat, while Deficiency causes cramping in both calves. Frequent urination with continued sweating indicates depletion of Body Fluids; Gui Zhi Tang must not be used erroneously. One should tonify deficiency and clear heat, treating cases where symptoms persist after erroneous medication. (Note on dosage: Ancient three liang equals modern one liang; ancient three sheng equals modern one sheng. To adapt ancient prescriptions to modern measures is difficult regarding fractional units. It is better to equate ancient and modern measures, halve the dose per administration, slightly increase the number of pieces, for practical convenience. Zhang Zhongjing stated that if symptoms persist after one dose, prepare half a dose again. This implies adding half to the original dose to ensure complete resolution. For those who cannot tolerate large doses, halving further is acceptable. *Zhou Hou Bei Ji Fang* mentions dividing one fen into two, or two zhu as one liang, using a cup instead of a sheng. Poor families may gather herbs temporarily. Coarse powder of five qian, decocted in two level cups of water to eight parts, is taken warm. With ginger and jujube, add three slices of ginger and three jujubes per dose, taken three times daily; up to six or seven doses if ineffective. Some conditions require full decoctions rather than powders due to severe pathology. Regarding Fuzi: one piece in a standard dose becomes one and a half pieces in a half-dose addition. Ancient texts did not split pieces to maintain potency. Large Fuzi over half a liang can serve as one and a half pieces; those over four qian can be standardized as one piece. Multiple slices are acceptable, as Zhang Zhongjing noted stronger individuals could take up to one whole piece.)

Shao Yao (Paeoniae Radix Alba) and Gan Cao (Glycyrrhizae Radix et Rhizoma) (each one and a half liang).
Finely chop, decoct in one and a half sheng of water until seven and a half he remain, strain, and take warm in two divided doses.

Gan Cao Gan Jiang Tang (Licorice and Dried Ginger Decoction)
Gan Cao (Glycyrrhizae Radix et Rhizoma) (two liang), Gan Jiang (Zingiberis Rhizoma) (one liang).
Decoct as described above.

Tiao Wei Cheng Qi Tang (Regulate the Stomach and Direct Downward the Qi Decoction)
Da Huang (Rhei Radix et Rhizoma) (one liang), Gan Cao (Glycyrrhizae Radix et Rhizoma) (half liang), Mang Xiao (Natrii Sulfas) (one large he).
Finely chop Da Huang and Gan Cao, decoct in one sheng of water until five he remain, strain, add Mang Xiao and dissolve, take warm in one cup. Stop when slight loose stools occur. If difficult to pass stool, administer another dose.

In Taiyang disease, if purgation is mistakenly used instead of diaphoresis, leading to unceasing diarrhea and a hurried pulse (Cu Mai), indicating the exterior pathogen remains, accompanied by wheezing and sweating, Ge Gen Huang Qin Huang Lian Tang (Kudzu, Scutellaria, and Coptis Decoction) is the primary treatment.

Huang Qin (Scutellariae Radix) (three qian), Huang Lian (Coptidis Rhizoma) (three liang), Gan Cao (Glycyrrhizae Radix et Rhizoma) (half liang), Gan Ge (Puerariae Radix) (two liang).
Finely chop, decoct in one and a half sheng of water until seven and a half he remain, strain, take warm in one cup, three times daily.
