When pathogenic factors invade the Lung, symptoms include pain in the skin, aversion to cold with fever, panting and upward rushing of Qi, sweating, and coughing that radiates to the shoulders and back. (Skin pain accompanied by aversion to cold and fever occurs because the skin and hair are the external correspondence of the Lung. Panting and sweating occur because the Lung governs Qi, leading to the loosening of the interstices (*Cou Li*). As the canopy of the five zang and six fu organs, the Lung resides above the diaphragm; thus, coughing affects the shoulders and back.) Treatment should involve needling between the Yunmen and Zhongfu points on the chest. (Zhongfu is located lateral to Yunmen and belongs to the Hand Taiyin Lung Meridian. However, deep needling of Yunmen is contraindicated as it may cause rebellious Qi.) Also, needle the areas beside the third and fifth thoracic vertebrae on the back. Press these areas quickly with the hand, and only needle where the patient feels a sense of comfort and relief. (The area beside the third vertebra corresponds to Feishu [BL13], and beside the fifth to Xinshu [BL12]; both belong to the Foot Taiyang Bladder Meridian. Where pressing brings relief, the true effective point is identified for needling.) Additionally, use Quepen (ST12) to disperse the pathogenic factors. (Quepen belongs to the Foot Yangming Stomach Meridian. The meridian pathway of the Hand Taiyin Lung emerges here; thus, this point is used to scatter Lung pathogens. Deep needling is contraindicated to avoid causing rebellious Qi.)

When pathogenic factors invade the Liver, symptoms include pain in the hypochondriac region, internal cold, retention of evil blood, frequent pulling sensations in the joints during movement, and occasional swelling of the feet. (Hypochondriac pain indicates pathology of the Liver Meridian. Internal cold results from Liver Wood overacting on the Spleen and Stomach. Retention of evil blood is due to the Liver's governance of blood. Pulling sensations in the joints occur because the Liver governs the sinews, which are occupied by pathogens. The Liver Meridian ascends from the medial aspect of the big toe to connect with the ankle, hence occasional foot swelling.) Treatment should involve needling Xingjian (LR2) to guide Qi from the hypochondrium. (Xingjian is the Ying-Spring point of the Foot Jueyin Liver Meridian, capable of guiding out Liver pathogens and stopping hypochondriac pain.) Tonify Zusanli (ST36) to warm the middle jiao. (Zusanli is a point on the Foot Yangming Stomach Meridian; tonification warms the stomach, alleviating internal cold.) Select visible collateral vessels to dissipate evil blood. (Needling visible collaterals of the Liver Meridian dissipates retained evil blood.) Needle the blue veins behind the ear to relieve joint pulling. (The Foot Shaoyang Gallbladder Meridian circulates around the ears. The Foot Jueyin Liver Meridian governs all sinews and forms an interior-exterior relationship with the Shaoyang; thus, needling the blue veins behind the ear relieves joint pulling.)

When pathogenic factors invade the Spleen and Stomach, symptoms include muscle pain. If Yang is in excess and Yin is deficient, there is heat in the middle jiao and excessive hunger. If Yang is deficient and Yin is in excess, there is cold in the middle jiao, borborygmus, and abdominal pain. If both Yin and Yang are in excess, or both are deficient, symptoms of both cold and heat may appear. (Muscle pain arises because the Spleen governs the muscles. Excess Yang leads to Yin deficiency; Yang pathogens enter the Fu organs, affecting the Yangming channel, causing heat in the middle jiao and hunger. Deficient Yang leads to Yin excess; Yin pathogens enter the Zang organs, affecting the Taiyin channel, causing cold, borborygmus, and pain. If Spleen/Stomach pathogenic qi is strong, it is excess of both Yin and Yang; if healthy qi is weak, it is deficiency of both. Thus, cold and heat symptoms follow accordingly.) All such conditions should be regulated via Zusanli (ST36). (As the He-Sea point of the Foot Yangming, it treats both Spleen and Stomach disorders.)

When pathogenic factors invade the Kidney, symptoms include bone pain and Yin Bi (obstruction). Yin Bi is characterized by tenderness that cannot be pinpointed by pressure, abdominal distension, lower back pain, difficulty defecating, pain in the shoulders, back, neck, and nape, and occasional dizziness. (The Kidney belongs to the Shaoyin channel and governs bones, hence bone pain and Yin Bi. For further details on Yin Bi, see *Su Wen: Zhi Zhen Yao Da Lun*, referenced in the Wind-Water-Qi category, Chapter 25.) Treatment should involve needling Yongquan (KI1) and Kunlun (BL60), draining any visible blood stasis. (Yongquan is the Jing-Well point of the Foot Shaoyin Kidney Meridian; Kunlun is the Jing-River point of the Foot Taiyang Bladder Meridian. According to the *Jing Mai* chapter, pain in the waist, spine, shoulders, back, neck, and nape relates to the Foot Taiyang channel, hence needling Kunlun. Other symptoms relate to the Shaoyin channel, hence needling Yongquan. These two meridians are exterior-interior pairs; any visible blood collaterals should be drained.)

When pathogenic factors invade the Heart, symptoms include heart pain, propensity for weeping/sadness, occasional dizziness and fainting. Treatment depends on excess or deficiency, regulating the Shu-Stream points. (Pathogens invading the Heart actually affect the Pericardium. Whether applying tonification or sedation, one should select the Shu-Stream points of the Hand Jueyin Pericardium Meridian.)
