Fever, sweating, aversion to wind, and a moderate pulse are named Wind Strike (Zhong Feng). Aversion to cold, body pain, vomiting or regurgitation, and tight pulses at both the Cun (inch) and Chi (cubit) positions are named Cold Damage (Shang Han). This is the outline of the pulse and symptoms for Wind and Cold pathogens. When discussed separately according to the Six Meridians (Liu Jing), each has specific syndromes and distinct pulses. When the Taiyang meridian (Bladder and Small Intestine) is affected, the pulses at both Cun and Chi positions are floating. When the Yangming meridian (Stomach and Large Intestine) is affected, the pulses are long. When the Shaoyang meridian (Gallbladder and Sanjiao) is affected, the pulses are wiry. When the Taiyin meridian (Spleen and Lung) is affected, the pulses are fine. When the Shaoyin meridian (Heart and Kidney) is affected, the pulses are weak. When the Jueyin meridian (Liver and Pericardium) is affected, the pulses are faint and moderate; hence it is said that the pulses differ. In Taiyang disease, absence of sweat is named Cold Damage, while spontaneous sweating is named Wind Strike. In Yangming disease, the ability to eat indicates Wind Strike, while inability to eat indicates Cold Damage. In Shaoyang disease, deafness, red eyes, chest fullness, and irritability indicate Wind Strike; whereas headache, fever, and wiry-thin pulses indicate Cold Damage. In Taiyin Wind Strike, the hands and feet are naturally warm; in Taiyin Cold Damage, there is spontaneous diarrhea without thirst. In Shaoyin Wind Strike, there is diarrhea with thirst; in Shaoyin Cold Damage, there is a desire to vomit and sleepiness. In Jueyin Wind Strike, there is tongue curling and testicular retraction; in Jueyin Cold Damage, there is hunger but no desire to eat. Therefore, it is said that the syndromes in the Three Yang meridians are specific, with floating pulses; the pulses in the Three Yin meridians are sunken, while moderate, tight, slow, and fine characteristics are common. If the pulse is floating but not moderate or tight, instead being slippery and rapid; or if it is sunken but not fine or slow, instead being soggy and urgent, these are the pulses of Wind-Warmth (Feng Wen) and Damp-Warmth (Shi Wen). By carefully examining the symptoms, errors can be avoided. As for Yang syndromes presenting Yin pulses, or Yin syndromes presenting Yang pulses, where the decision to follow the syndrome or the pulse is difficult, this belongs to Epidemic Diseases (Yi Zheng), which require different treatments from Cold and Warm diseases. Cold is originally a Yin pathogen; why is there Wind Strike within Cold Damage syndromes? Warmth is originally a Yang pathogen; why is there Damp-Warmth within Warmth syndromes? One must understand that Yin contains Yang, and Yang contains Yin. In Cold syndromes, Cold Damage is the primary aspect, and Wind Strike is the secondary aspect. In Warmth syndromes, Wind-Warmth is primary, and Damp-Warmth is secondary. Damp-Warmth corresponds to Cold Damage, and Wind-Warmth corresponds to Wind Strike. Epidemic diseases involve both Cold and Warmth; Warm-Epidemics are their normal state, while Cold-Epidemics are their variations. To know the normal and the variable, to understand correspondence, and to distinguish between primary and secondary aspects, one can discuss the principle of the mutual root of Yin and Yang! Those confined to partial views either recklessly use Cold-Cooling herbs or indiscriminately use Warm-Nourishing methods. Have they ever considered that syndromes of extreme Cold or extreme Heat are not common?
