温病一日，太阳受病。太阳主表，表谓皮肤也。病在皮肤之间，故头项腰脊痛。
温病二日，阳明受病。病在于肌肉，故肉热鼻干，不得眠，故可摩膏火炙，发汗而愈。
温病三日，少阳受病，故胸胁热而耳聋。三阳始传病讫，未入于脏，故可发汗而愈。
温病四日，太阴受病。太阴者，三阴之首也。三阳受病讫，传入于阴，故毒瓦斯入胸膈之
内，其病咽干腹满，故可吐而愈。
温病五日，少阴受病。毒瓦斯入腹，其病口热舌干而引饮，故可下而愈。
温病六日，厥阴受病。毒瓦斯入肠胃，其病烦满而阴缩，故可下而愈。
温病七日，病法当愈，此是三阴三阳传病竟故也。今七日病不除者，欲为再经病也。再
经病者，是经络重受病也。
温病八日以上病不解者，或者诸经络重受于病，或经发汗、吐、下之后，毒瓦斯未尽，所
以病证不罢也。
温病九日以上病不除者，或初一经受病即不能相传，或已传三阳讫而不能传于三阴，所
以停滞累日，病证不罢，皆由毒瓦斯未尽，表里受邪，经络损伤，腑脏俱病也。
夫人冬月触冒寒毒者，至春始发病，病初在表，或已发汗、吐、下而表证未罢，毒瓦斯不
散，故发斑疮。又冬月天时温暖，人感乖戾之气，未即发病，至春又被积寒所折，毒瓦斯不得
发泄，至夏遇热，温毒始发出于肌肤，斑烂隐轸如锦文也。
On the first day of warm disease, the Taiyang (Greater Yang) channel is affected. The Taiyang channel governs the exterior, and the exterior refers to the skin. Since the pathogen is between the skin, pain in the head, neck, waist, and spine occurs.
On the second day, the Yangming (Bright Yang) channel is affected. The pathogen resides in the muscles, resulting in feverish sensation in the flesh, dryness of the nose, and insomnia. At this stage, massage with ointments or moxibustion can be applied to induce sweating and achieve recovery.
On the third day, the Shaoyang (Lesser Yang) channel is affected, leading to heat in the chest and hypochondrium and deafness. The transmission of pathogenic factors through the three Yang channels is now complete, but the pathogen has not yet entered the Zang organs; therefore, sweating therapy can be used to achieve recovery.
On the fourth day, the Taiyin (Greater Yin) channel is affected. The Taiyin channel is the head of the three Yin channels. After the three Yang channels have been affected, the pathogen transmits into the Yin channels. Consequently, toxic qi enters the interior of the chest and diaphragm, causing dryness of the throat and abdominal fullness. In this case, emesis therapy can be used to achieve recovery.
On the fifth day, the Shaoyin (Lesser Yin) channel is affected. Toxic qi enters the abdomen, manifesting as heat in the mouth, dryness of the tongue, and a desire to drink. Purgative therapy can be employed to achieve recovery.
On the sixth day, the Jueyin (Terminal Yin) channel is affected. Toxic qi enters the intestines and stomach, presenting with irritability, fullness, and retraction of the genitals. Purgative therapy can be used to achieve recovery.
By the seventh day, the disease should theoretically resolve, as the transmission of pathogenic factors through the three Yin and three Yang channels is complete. If the disease persists beyond seven days, it indicates a "re-entry into the meridians" (Zai Jing Bing). This refers to the meridians being affected again.
If the disease persists for eight days or more without resolution, it may be due to repeated infection of various meridians, or because toxic qi remains after sweating, emesis, or purgation therapies, thus preventing the cessation of symptoms.
If the disease persists for nine days or more without resolution, it may be because the initial pathogen in one channel failed to transmit further, or because transmission through the three Yang channels was completed but failed to enter the three Yin channels. This leads to stagnation over several days and persistent symptoms. All these scenarios result from incomplete elimination of toxic qi, invasion of both the exterior and interior, damage to the meridians, and simultaneous involvement of the Fu and Zang organs.
Generally, if an individual encounters cold toxicity in winter, the disease may manifest in spring. Initially located at the exterior, if sweating, emesis, or purgation therapies are applied but the exterior syndrome persists, the toxic qi fails to disperse, leading to the eruption of macules and sores. Alternatively, if the weather is unusually warm in winter and the person contracts erratic Qi, the disease may not manifest immediately. In spring, accumulated cold may suppress the body, preventing the venting of toxic qi. When summer heat arrives, warm toxicity erupts from the skin and muscles, presenting as mottled lesions and hidden rashes resembling brocade patterns.
