If elderly people suffer from "air-conditioning disease," due to their decreased resistance, they are particularly prone to "fear of cold-damage disease." Although fever may appear, the pulse is not floating but sinking. Floating represents yang, while sinking represents yin. When a yang condition manifests with a yin pulse, it is considered adverse, and this condition is fraught with danger, often leading to rapid death. This condition is often accompanied by symptoms such as phlegm rales, panting, cold and non-warm fingers, listlessness, and a tendency to tilt the head and want to sleep. These symptoms and signs are called "shaoyin cold-damage disease." It is crucial to act decisively and urgently apply the method of warming the meridians and tonifying yang:
Aconite Lateral Root 12g, Prepared Liquorice Root 10g, Ephedra 3g
, to be decocted and taken immediately. This formula is called Ephedra, Aconite, and Liquorice Decoction, which disperses the cold of Taiyang (EX-HN5) externally and warms the yang of shaoyin internally. Aconite Lateral Root is powerful and robust, aiding the righteous and correcting the evil, treating both the exterior and interior. It moderates the swiftness of Ephedra and enhances the tonifying effect of Liquorice Root. After taking it, the condition can often turn from critical to stable.

If symptoms such as palpitation, dizziness, panting, cold back, difficulty in urination, body swelling, heavy legs, a sinking and wiry pulse, a swollen tongue with a slippery coating appear, this indicates cold damage to shaoyin, heart and kidney yang deficiency, and the inability to warm yang qi to promote diuresis. In this case, the combination of Ling Gui Zhu Gan Tang and True Warrior Decoction (Aconite Lateral Root, Cinnamon Twig, Peony Root, Poria, Fresh Ginger Rhizome, White Atractylodes Rhizome, Prepared Liquorice Root) can be used to warm and tonify the heart and kidney yang qi, transforming the yin pathogen of water-cold.
