Taiyang Zhongyue (Heatstroke affecting the Taiyang channel) presents with fever, aversion to cold, heaviness of the body, and pain. The pulse is wiry, thin, and slow. After urination, there is a sensation of chilliness and piloerection. The hands and feet are cold. Upon slight exertion, the body becomes hot; the mouth opens, and the anterior teeth are dry. If sweating methods are applied, aversion to cold will worsen; if warm needle therapy is used, fever will intensify; if purgation is frequently employed, strangury (dysuria) will become severe.
Zhongyue refers to heatstroke. Summer-heat is one of the Six Evils. When it affects the Taiyang channel, it manifests as alternating chills and fever. However, summer-heat is a Yang pathogen, yet this syndrome presents with body heaviness and pain, and the pulse is wiry, thin, and slow. Although named Zhongyue, it actually involves dampness. The chilliness and piloerection after urination occur because Taiyang governs the exterior and internally connects with the Bladder; urination temporarily depletes Qi. Cold hands and feet result from Yang Qi gathering internally and failing to reach the extremities; thus, slight exertion causes Qi to escape and the body to heat up. Opening the mouth and dry anterior teeth indicate excessive heat within and dissipating Qi on the outside. Generally, although summer-heat is a Yang pathogen, its Qi often combines with Dampness, reflecting the principle of Yang seeking Yin. Summer-heat enters via Dampness, and summer-heat resides within Dampness, reflecting the image of Yin enveloping Yang. Treatment should follow the method for resolving Wind-Damp: use Acrid substances to disperse Dampness and Cold substances to clear Summer-heat. Sweating merely damages the exterior; warm needles exacerbate heat; purgation causes heat to sink inward, leading to various complications. None of these are correct treatments for Summer-heat-Dampness.
Taiyang Zhongre (Summer-heat Heat in Taiyang) is known as He disease (Zhu Xia). It presents with sweating, aversion to cold, body heat, and thirst.
Zhongre is also heatstroke. "He" refers to the Qi of summer-heat. Aversion to cold occurs because heat entering relaxes the skin and opens the Cou-li (pores); when open, one feels chilly (Sasara), which differs from the aversion to cold in Cold Damage. Sweating, fever, and thirst indicate blazing heat in both the interior and exterior, with Stomach Yin nearing exhaustion, seeking relief from water. This is the syndrome of heatstroke without Dampness.
Taiyang Zhongshi (Dampness in Taiyang) presents with body heat, painful heaviness, and a faint pulse. This is caused by injury from cold water in summer, where water Qi circulates in the skin.
When Summer-heat invades the person, those with Yin deficiency and excess Fire harbor Summer-heat within Fire, manifesting as sweating, vexation, and thirst. Those with Yang deficiency and excess Dampness harbor Summer-heat within Dampness, manifesting as body heat and painful heaviness. Therefore, Summer-heat diseases often involve Dampness, and treating Dampness is equivalent to treating Summer-heat. Thus, *Jin Gui Yao Lue* uses a single herb formula of Geng Ti (Cucumis Trichosanthis Fruit) to remove water from the body, face, and limbs. Once the water is removed, Summer-heat has no basis and resolves spontaneously. This is the syndrome of heatstroke complicated by Dampness.
