太陽之爲病，脉浮，頭項強痛而惡寒。
太阳之为病，脉浮，头项强痛而恶寒。
tài yáng zhī wéi bìng mài fú tóu xiàng qiáng tòng ér wù hán
When the taiyang falls ill, the pulse is floating, the head and nape are stiff and painful, and there is aversion to cold.
**「惡寒」五篇共25見**（經文，不含成注），本文引第5篇第01段、第5篇第08段、第1篇第30段。
病有發熱惡寒者，發於陽也；無熱惡寒者，發於陰也。發於陽者七日愈，發於陰者六日愈，以陽數七、陰數六故也。
病有发热恶寒者，发于阳也；无热恶寒者，发于阴也。发于阳者七日愈，发于阴者六日愈，以阳数七、阴数六故也。

Illness with fever and aversion to cold arises from yang; illness with aversion to cold but no fever arises from yin. Yang cases heal in seven days, yin cases in six, because the yang number is seven and the yin number six.
惡寒一證，在表為衛氣與邪爭，在裏為陽氣之虚；同名而異治，全在脉與有熱無熱上分。
師曰：病人脉微而濇者，此爲醫所病也。大發其汗，又數大下之，其人亡血。病當惡寒，後乃發熱，無休止時。夏月盛熱，欲著複衣，冬月盛寒，欲裸其身。所以然者，陽微則惡寒，陰弱則發熱。此醫發其汗，令陽氣微，又大下之，令陰氣弱。五月之時，陽氣在表，胃中虚冷，以陽氣内微，不能勝冷，故欲著複衣。十一月之時，陽氣在裏，胃中煩熱，以陰氣内弱，不能勝熱，故欲祼其身。又陰脉遲濇，故知血亡也。
师曰：病人脉微而涩者，此为医所病也。大发其汗，又数大下之，其人亡血。病当恶寒，后乃发热，无休止时。夏月盛热，欲著复衣，冬月盛寒，欲裸其身。所以然者，阳微则恶寒，阴弱则发热。此医发其汗，令阳气微，又大下之，令阴气弱。五月之时，阳气在表，胃中虚冷，以阳气内微，不能胜冷，故欲著复衣。十一月之时，阳气在里，胃中烦热，以阴气内弱，不能胜热，故欲祼其身。又阴脉迟涩，故知血亡也。

The master said: “When a patient’s pulse is faint and astringent, he has been harmed by the physician. Sweating him greatly and purging him repeatedly, the man loses blood. The illness should bring aversion to cold and afterwards fever, without cease.” In summer’s great heat he wants thick garments; in winter’s great cold he wants to go bare. The reason is that faint yang means aversion to cold and weak yin means fever. The physician sweated him and made the yang qi faint, then purged him greatly and made the yin qi weak. In the fifth month the yang qi is in the exterior and the stomach is cold within; because the yang qi is faint inside it cannot master the cold, so he wants thick garments. In the eleventh month the yang qi is in the interior and the stomach is hot and restless; because the yin qi is weak inside it cannot master the heat, so he wants to go bare. Moreover the yin pulse is slow and astringent, so one knows the blood is lost.
