Zhang Zhongjing's prescriptions all adhere to the ancient method of weighing with units of zhu (2.5 grams) and liang (37.5 grams), which differs from modern practice. (The prescriptions attached from *Qianjin Fang* and *Waitai Miyao*, etc., are also like this.) The term "ju" (chewing/crushing) refers to today's method of chopping herbs into pieces the size of hemp seeds or beans. When it says "one sheng" (a unit of volume), it refers to a large white cup today. When it mentions "zhu", six zhu constitute one fen (which is equivalent to two qian and half). Twenty-four zhu constitute one liang. When it says "three liang", it means one liang today. When it says "two liang", it means six qian and half today. For prescriptions with larger dosages, taking only one-third of the original amount is sufficient.
(And accompanying diagrams; this is the original text by Zhang Zhongjing.)
*Zisheng Jing* states: In treating Shanghan (Cold Damage), moxibustion is applicable only for Yin syndromes, while acupuncture should be used for all others. Yin syndrome refers to Zhonghan (Strike of Cold). The remaining types of Shanghan all belong to the category of heat diseases. Heat diseases are suitable for needling; needling involves using needles to drain heat. The use of burning needles mentioned in the previous chapter actually aids heat, thereby leading to adverse conditions. Needles heated by fire are essentially similar to moxibustion. Generally speaking, moxibustion tonifies more and drains less; acupuncture drains more and tonifies less. Understanding the principles of acupuncture and moxibustion allows one to treat diseases with reasonable success.
In Taiyang disease, if after the initial administration of Guizhi Tang (Cinnamon Twig Decoction), the patient experiences contrary irritability and the condition does not resolve, first needle Fengchi (GB20) and Fengfu (GV16), then administer Guizhi Tang, and the disease will heal. (This clause regarding Taiyang disease should be Wind Strike syndrome, characterized by fever, sweating, aversion to wind, and a slow pulse, which constitutes the indication for Guizhi Tang. Cheng Wuji's commentary notes: Irritability indicates heat. After the initial dose of Guizhi Tang, sweating should occur, leading to a cool and harmonious body. If contrary irritability persists unresolved, it indicates that the wind pathogen is severe and has not yet dispersed. First needle Fengchi and Fengfu to unblock the Taiyang meridians and vent the wind qi, then administer Guizhi Tang to disperse the pathogen, resulting in healing.)
[Diagram of Fengchi and Fengfu Acupoints]
Fengchi (GB20) consists of two points. *Tujing* states they are located behind the temporal region, in the depression at the hairline. (*Huoren Shu* states they are at the back of the neck, which should be interpreted as the lateral posterior neck. This is because the Temporal acupoint is originally located in the depression below the Yuzhen bone; these two points are further posterior/inferior to the Temporal point. Here, "posterior" implies inferior.) They are the intersection of the Foot-Shaoyang Gallbladder Meridian and the Yang-Linking Vessel. It is appropriate to insert the needle 3 cun; for individuals with thick muscles, insertion may be up to 5 cun. Retain the needle for seven breaths. Moxibustion is contraindicated.
Wang Hu notes: *Tujing* originally stated an insertion depth of 7 cun, but now we only insert 3 cun, following the说法 of *Jiayi Jing*. "Retain for seven breaths" means retaining the needle in the acupoint for the duration of seven exhalations to vent wind-heat pathogens.
Fengfu (GV16) is a single point. *Tujing* states it is also known as Sheben, located one cun above the nape hairline, within the depression inside the major tendons. (*Huoren Shu* states: At the back of the neck, one cun into the hairline. Upon speaking loudly, the muscle immediately rises; upon ceasing speech, it immediately flattens.) It is the intersection of the Du Vessel and the Yang-Linking Vessel. It is suitable for needling, with an insertion depth of only 3 cun. For individuals with thin muscles, insert 2 cun. Withdraw the needle while the patient exhales. Moxibustion is strictly contraindicated, as it can cause aphonia (loss of voice).
A question arises: Fengchi and Fengfu belong to the pathways of the Foot-Shaoyang Meridian and the Du Vessel, having no direct relation to the Taiyang Meridian. Why did Zhang Zhongjing needle them? I answer: Fengchi is located on the third row of acupoints when the head is in a prone position; Fengfu is on the central row. The second row of acupoints is precisely where the Taiyang Meridian travels. Thus, Fengchi and Fengfu actually run alongside the Taiyang Meridian. Moreover, both points are intersections with the Yang-Linking Vessel. The Yang-Linking Vessel is the general gathering of all Yang meridians. Once the qi of all Yang meridians is vented, why worry about the wind-heat of the Taiyang meridian not being expelled?
The above is one case of Taiyang disease suitable for acupuncture. (Extracted from Volume 2, Taiyang Treatment Methods, of the original treatise and included here.)
In Shanghan, if abdominal fullness and delirium occur, and the Cun Kou (radial) pulse is floating and tight, this is Liver Wood overacting on Spleen Earth, named Zong (Vertical/Unrestrained) needling of Qimen (LR14). (Shanghan presenting with abdominal fullness and delirium occurs because the patient initially had Taiyang Shanghan, and subsequent symptoms include abdominal fullness and delirium. Abdominal fullness indicates pathogen transmission to the Spleen; delirium indicates transmission to the Stomach. If the Cun Kou pulse presents as floating and tight, this is not the Taiyang pathogen transmitting inward. Diagnostic methods state that a floating and tight pulse corresponds to a Xian (wiry) pulse. A wiry pulse anterior to both Guan positions indicates that the abdominal fullness and delirium are caused by excessive wind-heat from the Liver Meridian overacting on the Spleen. When Spleen disease presents with a Liver pulse, it is Wood overacting on Earth, termed "Zong". Zong means straight/direct, indicating that since Wood naturally controls Earth, its overaction is particularly direct. Qimen is the Front-Mu point of the Liver. Cheng Wuji's commentary states: Needling it drains the excess qi of the Liver Meridian.)
A question arises: In Taiyang Shanghan, the pulse is typically floating and tight. In this case, the Cun Kou pulse is floating and tight, yet Zhang Zhongjing exclusively attributes it to Liver overacting on Spleen, and Cheng Wuji adds that it is due to excess Qi in the Liver Meridian. How should physicians distinguish this? I answer: In Taiyang Shanghan, the Chi and Cun positions both present floating and tight pulses, because the Chi position governs the Bladder, which is the Taiyang Cold-Water meridian; floating and tight indicates exceptional abundance of wind-cold qi. Here, only the Cun position is mentioned, not the Chi, indicating that the Bladder meridian qi is not excessive. Furthermore, according to Zhang Zhongjing's pulse methodology, mentioning "Chi and Cun" includes the "Guan". The Left Guan governs the Liver, and the Right Guan governs the Spleen. If the Cun Kou pulse is floating and tight, the pulses anterior to both Guan positions become wiry. Is this not a diagnosis of Liver overacting on Spleen? At this time, if one were to use herbs to purge the Spleen, the Earth would suffer from Wood encroachment and could not withstand the attack. It is appropriate to drain the Liver to remove wind-heat. This discussion of acupuncture is far more rapid and effective than discussing herbal medicine.
