伤寒，是寒气侵袭皮肤，与血气相搏结，导致腠理（皮肤纹理及汗孔）闭塞致密，气机不能宣泄，郁积而生热，因此出现头痛、身体疼痛以及高热。如果大小便不通，是因为寒邪搏结于气分而生热，热邪流入大小肠，导致肠道涩滞结聚而排便困难。凡是大小便不通，体内的热邪就无法平息，可能出现干呕，或胡言乱语。如果气机上逆，则会导致心腹胀满。
伤寒，是寒气侵袭皮肤，与血气相搏结，导致腠理闭塞致密，气机不能宣泄，郁积而生热，因此出现头痛、身体疼痛以及高热。如果出现腹部胀满，是因为热邪进入腹部，传变至脏腑，脏气结聚，所以导致腹部胀满。如果兼夹毒邪，则会出现腹部胀满、心烦等症状。
伤寒，是寒气侵袭皮肤，与血气相搏结，导致腠理闭塞致密，气机不能宣泄，郁积而生热，因此出现头痛、身体疼痛以及高热。如果出现咽喉疼痛，是因为心胸部位热盛，气机上冲至咽喉，所以导致疼痛。如果兼夹毒邪，则咽喉疼痛并伴有结肿，导致水浆难以下咽，如果毒邪再入于心，出现烦闷症状的，预后不良，可能导致死亡。
伤寒，是寒气侵袭皮肤，与血气相搏结，导致腠理闭塞致密，气机不能宣泄，郁积而生热，因此出现头痛、身体疼痛以及高热。咳嗽的症状，是因为邪气在肺。肺外合皮毛且主司气，伤寒邪气先侵袭皮肤，随气机进入肺脏，所以导致咳嗽。病情严重的，咳出脓血。
伤寒，是寒气侵袭皮肤，与血气相搏结，导致腠理闭塞致密，气机不能宣泄，郁积而生热，因此出现头痛、高热以及身体疼痛。病愈之后仍然咳嗽，是因为邪气仍然停留在肺中未完全清除。寒邪伤人，先侵袭皮毛。皮毛是肺的外候，肺主气，寒邪搏结肺气，进而传入五脏六腑，导致表里俱热。热退之后，肺脏尚未调和，邪气未尽，邪气随气机进入肺脏，与肺气相搏结，所以伤寒后仍然患有咳嗽。
Shaoyang disease (Cold Damage) refers to cold pathogenic factors invading the skin and contending with blood and qi, causing the couli (skin pores and tissue spaces) to become closed and dense. This prevents the venting and discharge of qi, leading to accumulation and generation of heat. Consequently, symptoms such as headache, body pain, and high fever occur. If there is obstruction of both urination and defecation, it is because cold contends with qi generating heat, which then flows into the large and small intestines, causing dryness, stagnation, and blockage. Whenever urination and defecation are obstructed, internal heat does not subside; this may manifest as dry retching or incoherent speech. If qi rebels and moves upward, it results in distension and fullness of the heart and abdomen.

This prevents the venting and discharge of qi, leading to accumulation and generation of heat. Consequently, symptoms such as headache, body pain, and high fever occur. If abdominal distension is present, it is because heat has entered the abdomen and transmitted to the zang organs. The qi of the zang organs becomes knotted and aggregated, thus causing abdominal distension. If accompanied by toxic pathogens, symptoms include abdominal distension and vexation.

This prevents the venting and discharge of qi, leading to accumulation and generation of heat. Consequently, symptoms such as headache, body pain, and high fever occur. If sore throat is present, it is because heat is excessive in the chest and heart, causing qi to rush upward to the throat, thus inducing pain. If accompanied by toxic pathogens, the throat becomes painful with swelling and knotting, preventing the intake of water and food. If the toxin re-enters the heart and causes severe vexation, the prognosis is fatal.

This prevents the venting and discharge of qi, leading to accumulation and generation of heat. Consequently, symptoms such as headache, body pain, and high fever occur. Cough indicates that the pathogenic factor is in the Lung. The Lung governs the skin and hair and controls qi. The Shaoyang pathogen first invades the skin and follows the qi into the Lung, thus causing cough. In severe cases, pus and blood may be expectorated.
Shaoyang disease (Cold Damage) refers to cold pathogenic factors invading the skin and contending with blood and qi, causing the couli to become closed and dense. This prevents the venting and discharge of qi, leading to accumulation and generation of heat. Consequently, symptoms such as headache, high fever, and body pain occur. Cough persisting after recovery indicates that the pathogenic factor remains lodged in the Lung and has not been fully cleared. Cold pathogens injure the body by first invading the skin and hair. The skin and hair are the external manifestations of the Lung, which controls qi. Cold contends with Lung qi and enters the five zang and six fu organs, resulting in heat in both the exterior and interior. After the heat subsides, the Lung has not yet harmonized, and the pathogen remains. The pathogen follows the qi into the Lung and contends with Lung qi, thus causing persistent cough after Shaoyang disease.
