（论一首）
论曰∶舌者心主，小肠之候也。善用机衡能调五味也。凡有所啖，若多咸则舌脉凝而变
色，多食苦则舌皮槁而外毛焦枯，多食辛则舌筋急而爪枯干，多食酸则舌肉肥而唇揭，多食
甘则舌根痛而外发落。又曰∶心欲苦，肺欲辛，肝欲酸，脾欲甘，肾欲咸，此五味内合五脏
之气也。若脏热则舌生疮引唇揭赤。若腑寒则舌本缩，口噤唇青，寒宜补之，热宜泻之，不
寒不热根据脏腑调之。

（论述一篇）
论述说：舌是心的外候，也是小肠状况的反映。善于运用权衡调节五味对人体健康至关重要。凡是饮食，如果过咸，则舌部脉络凝滞而变色；过食苦味，则舌体干枯而体表毛发焦枯；过食辛味，则舌筋拘急而指甲枯干；过食酸味，则舌体肌肉肥厚而嘴唇翻揭；过食甘味，则舌根疼痛而头发脱落。又说：心喜苦味，肺喜辛味，肝喜酸味，脾喜甘味，肾喜咸味，这是五味在内与五脏之气相合的道理。如果脏腑有热，则舌上生疮并牵引嘴唇翻揭发红。如果腑脏有寒，则舌体收缩，口噤唇青，寒证适宜用补法，热证适宜用泻法，不寒不热则根据脏腑情况进行调理。
(Two sections on pulse diagnosis, three prescriptions, two moxibustion methods)
Excess Heat of the Small Intestine
If the pulse at the Cun Kou position on the left hand, anterior to the Ren Ying point, presents as an excess Yang pulse, it indicates a disease of the Hand-Taiyang (Small Intestine) meridian. The patient suffers from fever, with sweat appearing intermittently or absent. There is mental restlessness and fullness, heaviness of the body, and sores in the mouth. This is termed Excess Heat of the Small Intestine.
Prescription for treating heat distension of the Small Intestine and oral ulcers:
Chai Hu (Bupleuri Radix), Ze Xie (Alismatis Rhizoma), Ju Pi (Citri Reticulatae Pericarpium, alternatively Jie Geng / Platycodonis Radix), Huang Qin (Scutellariae Radix), Zhi Shi (Aurantii Fructus Immaturus), Xuan Fu Hua (Inulae Flos), Sheng Ma (Cimicifugae Rhizoma), Mang Xiao (Natrii Sulfas) [each 2 liang], Sheng Di Huang (Rehmanniae Radix Praeparata) [1 sheng, sliced].
The above nine ingredients are cut into small pieces, decocted in one dou of water until three sheng remain, filtered to remove dregs, then Natrii Sulfas is added. Divide into two doses.
Prescription for treating heat accumulation and obstruction causing fullness in the Small Intestine:
Da Huang (Rhei Radix et Rhizoma), Shao Yao (Paeoniae Radix), Ting Li (Semen Lepidii seu Descurainiae) [each 2 liang], Da Ji (Euphorbiae Pekinensis Radix), Pu Xiao (Natrii Sulfas) [each 3 liang], Ba Dou (Crotonis Fructus) [7 seeds], Xing Ren (Armeniacae Semen Amarum) [50 seeds].

For excess heat and fullness of the Small Intestine, moxa moxibustion can be applied to Yin Du (ST15). The number of moxa cones should correspond to the patient's age. The point is located one cun lateral to both sides of Zhong Wan (CV12). For dysentery with pus and blood due to Small Intestine heat, moxa moxibustion can be applied to Hun She (EX-LE4) for one hundred cones; reduce for children. The point is located one cun lateral to both sides of the umbilicus.
Additionally, moxa moxibustion can be applied to Xiao Chang Shu (BL27) for seven cones.
Deficiency Cold of the Small Intestine
If the pulse at the Cun Kou position on the left hand, anterior to the Ren Ying point, presents as a deficient Yang pulse, it indicates a disease of the Hand-Taiyang (Small Intestine) meridian. The patient suffers from unilateral headache at the side of the head, and pain in the ears and cheeks. This is termed Deficiency Cold of the Small Intestine.

(One treatise)
Treatise states: The tongue is the external manifestation of the Heart and reflects the condition of the Small Intestine. It is essential to skillfully balance the Five Flavors. Regarding diet, excessive salt causes the tongue vessels to stagnate and change color; excessive bitter flavor causes the tongue tissue to wither and external hair to become dry and brittle; excessive pungent flavor causes tongue tendons to contract and nails to become dry; excessive sour flavor causes tongue flesh to become hypertrophic and lips to peel; excessive sweet flavor causes pain at the root of the tongue and hair loss. Furthermore, it is said: The Heart desires bitter, the Lung desires pungent, the Liver desires sour, the Spleen desires sweet, and the Kidney desires salty. These five flavors internally harmonize with the Qi of the Five Zang organs. If the Zang organs have heat, sores appear on the tongue, leading to redness and peeling of the lips. If the Fu organs have cold, the tongue base retracts, the mouth becomes locked, and lips turn cyan. Cold conditions are suitable for tonification, heat conditions are suitable for purgation, and if neither cold nor heat predominates, regulation should be based on the Zang and Fu organs.
