60. In the autumn, the climate is dry, and mild dryness can lead to dry symptoms, while severe dryness may cause a sensation of coldness. Dryness can transform into dampness or further convert into heat. This article discusses the main characteristics of dryness and introduces its mother-son relationship and counteraction, providing a better understanding of the nature of dryness. Severe dryness can lead to a sense of coldness because coldness is related to water, and water is the offspring of metal. When transforming dryness into dampness, the role of earth should be considered, as damp earth is the mother of dampness. As for treatment, the article mentions the phrase, "Yangming and Jueyin, not from the exterior but from the interior," indicating that when treating dryness, the focus should be on the interior rather than solely on the exterior. The article also notes that when treating diseases of the Yangming meridian, special attention should be given to dryness; however, in this article, the specific treatment methods for dry metal-based qi are not discussed in detail but are included in the discussion of cold-damp symptoms. According to the medical cases of Ye Shi, dryness symptoms are more common during the season of late summer when there is internal dryness and external coolness. Similar situations are also mentioned in Zhang Zhongjing's "Essentials from the Golden Cabinet," especially in diseases such as abdominal pain and malarial disorders.
